   Source: Best practices in business process redesign: an overview and qualitative evaluation of successful redesign heuristics.
2. Description: The application of integral technology involves embedding advanced tools or systems directly into the core of a business process to overcome existing limitations—be they logistical, communicative, informational, or physical. Technology can act as a catalyst for process innovation by automating routine activities, enabling real-time information access, and facilitating better coordination among stakeholders. Examples include the implementation of workflow management systems, document management platforms, and AI-powered decision-support tools. These technologies not only streamline operations but also enhance transparency and consistency in execution. For instance, a customer service process supported by a CRM system allows agents to access complete interaction histories, improving the quality and speed of support. However, the integration of technology must be approached holistically—considering training, change management, and ongoing maintenance to ensure adoption and sustainable benefits.
3. Key Takeaways:
   1. Overcoming Limitations: Technology eliminates or reduces physical and informational constraints in traditional processes.
   2. Process Automation: Repetitive and manual tasks can be automated, reducing operational time and error rates.
   3. Information Availability: Systems like Document Management provide open access to relevant data, improving service quality.
   4. Empowerment Through Tools: New technologies can fundamentally reshape roles and capabilities within a process.
   5. Implementation Requires Care: Adoption entails training, cost, and potential resistance, which must be managed proactively.
4. Performance Considerations: In general, new technology can offer a range of positive effects on process performance. For example, a Workflow Management System may reduce time spent on coordination tasks, while a Document Management System can enhance service quality by ensuring all participants have access to relevant case information. Furthermore, technology can introduce fundamentally new capabilities, altering how a business process is executed. However, these benefits come with significant costs, including procurement, development, implementation, user training, and ongoing maintenance. Moreover, the introduction of new tools may provoke resistance or anxiety among employees, which can negatively impact workflow quality if not addressed appropriately.

Appoint case managers

1. Definition: Assign a responsible individual for handling each case type Assign a person as a manager for a case who is responsible and accountable for all decisions taken during the process execution.  Best practices in business process redesign: an overview and qualitative evaluation of successful redesign heuristics.
2. Description: The Case Manager plays a crucial role within the business process, serving as a central point of coordination and oversight for a specific case. This role entails managing the case from initiation to resolution, ensuring that all necessary steps and actions are carried out effectively and efficiently. The Case Manager serves as the primary contact for the case, facilitating communication and collaboration among various stakeholders involved. They gather relevant information, analyze the case requirements, assign tasks to appropriate resources, and monitor the progress and quality of work items. While the Case Manager takes responsibility for the case, it is important to note that they may collaborate with and delegate tasks to other resources within the process, such as subject matter experts or specialized teams. This collaborative approach ensures that the case is handled comprehensively, leveraging the expertise of different individuals while maintaining centralized oversight and accountability under the guidance of the Case Manager. Example: An organisation assigns a new resource as a recruitment process manager responsible for decision-making related to process flow, resource allocation, data handling, and other relevant decisions. Implementation: Involves identifying the process to be managed, selecting a suitable resource as the case manager, providing the necessary authority and resources to carry out the responsibilities, and ensuring effective communication and collaboration among the resources involved.
3. Key Takeaways:
   1. Central Coordination : The Case Manager serves as the central point of coordination and oversight for a specific case within the business process.
   2. Communication Hub Acting as the primary contact, the Case Manager facilitates communication and collaboration among stakeholders involved in the case.
   3. Task Assignment : The Case Manager assigns tasks to appropriate resources, ensuring that work items are distributed efficiently.
   4. Progress Monitoring : They monitor the progress and quality of work items, ensuring timely and effective resolution of the case.
   5. Collaborative Approach: While the Case Manager takes responsibility, they may collaborate with and delegate tasks to other resources within the process, optimizing expertise and efficiency.
4. Performance considerations: The primary objective of this heuristic is to enhance the external quality of a business process. By appointing a case manager as a single point of contact, the process becomes more transparent from the client's perspective, resulting in improved client satisfaction. Additionally, having someone accountable for rectifying mistakes can positively impact the internal quality of the process. It is important to note that assigning a case manager carries financial implications due to the allocation of resources for this role.

Automate activities

1. Definition: Consider automating activities. A technique for automating routine and repetitive tasks to improve efficiency and accuracy. Best practices in business process redesign: An overview and qualitative evaluation of successful redesign heuristics.
2. Description: The "Activity Automation" pattern centers around using technology to automate repetitive and routine tasks within a process. By automating these activities, organizations can reduce errors, save time, and allocate resources more effectively. Activity Automation can be accomplished through various tools such as robotic process automation (RPA) or workflow management systems. The primary objective of Activity Automation is to eliminate manual effort and reduce the reliance on human intervention for tasks that are repetitive and rule-based. By leveraging automation technology, organizations can improve accuracy, enhance efficiency, and streamline their processes. Employees are freed from mundane and routine activities, allowing them to focus on more strategic and value-added tasks that require human expertise. 
   Implementing Activity Automation brings significant performance implications to a process. By automating routine tasks, organizations can reduce the risk of human errors, enhancing data accuracy and quality. Time and resource savings are achieved as tasks that were previously manually performed can now be executed efficiently and effectively through automation. This leads to improved overall process efficiency, allowing for faster completion of tasks and reduced cycle times. 
   Furthermore, Activity Automation enables employees to shift their focus from repetitive tasks to more strategic activities. This not only improves job satisfaction but also enhances the organization's ability to innovate and deliver higher-value outcomes. By leveraging automation technology, organizations can optimize resource allocation, reduce costs, and achieve operational excellence.
3. Key Takeaways: Automate Routine Tasks Activity Automation involves using technology to automate repetitive and routine tasks, such as data entry or report generation. Semi-Automate Instead of fully automating a task, automatic support also be considered. Tools for Automation Activity Automation can be achieved through robotic process automation (RPA) or workflow management systems.
4. Performance considerations: The positive result of automating tasks can be, in particular, that the tasks can be tasks can be carried out faster, at a lower cost and with a better result. An obvious disadvantage is that developing a system to perform a task can be costly. In general, a system that performs a task is also less flexible in dealing with fluctuations than a human resource.

Buffer information

1. Definition: Buffer external information and subscribe to updates Instead of requesting information from an external source, buffer it and subscribe to updates.
2. Description: Obtaining information from other parties is a major, time-consuming part in many workflows. By having information directly available when it is required, throughput times may be substantially reduced. Note that this buffering is a weak form of the integration pattern. Instead of direct access to the original source of information in the integration alternative a copy is maintained.
3. Key Takeaways:
   Faster Access to Information: Buffered data allows immediate retrieval, reducing delays caused by external requests.
   Improved Throughput Time: By avoiding repeated calls to external sources, overall process duration can be significantly shortened.
   Lightweight Alternative to Integration: Buffering provides some benefits of integration without the complexity of full system coupling.
   Requires Update Mechanism: Subscribing to updates ensures buffered information remains reasonably current and reliable.
   Cost vs. Utility Trade-off: Regular updates and storage may incur significant costs, especially if much of the buffered data is rarely used.
4. Performance considerations: This pattern can be compared to the caching principle microprocessors apply. Of course, the subscription fee for information updates may be rather costly. This is especially so when we consider the situation that an information source may contain far more information than is ever used. Substantial cost may also be involved with storing all the information.

Consolidate Work

1. Definition: Collect similar work items and work in batches. Rather than addressing each case individually, consolidate multiple cases and execute activities in batches. Best practices in business process redesign: an overview and qualitative evaluation of successful redesign heuristics.
2. Description: Batch processing is an organized method of handling tasks by grouping similar activities together and executing them collectively, as opposed to dealing with each task individually. This systematic approach aims to enhance efficiency and streamline workflows by minimizing transitions between different types of tasks, allowing for a more structured and optimized workflow.
   Consider batch processing as a way of categorizing and addressing tasks akin to organizing household chores. Much like cleaning all the rooms at once instead of moving back and forth, batch processing involves identifying tasks that share commonalities, such as similar steps or resource requirements. For instance, tasks like processing invoices or sorting data entries are prime candidates for grouping into batches, allowing for a more efficient and effective handling of these activities.
   Application: Batch processing is about figuring out which tasks can be done together because they're kind of alike. For example, if you're processing a bunch of invoices or sorting through data entries, these are tasks that share common steps. So, you group them into batches and handle them more efficiently. While batch processing offers notable advantages, it is essential to maintain a focus on quality control and flexibility. Ensuring that each batch meets predefined standards is crucial, and the system should be adaptable to changes in task requirements. Regular monitoring of key performance indicators facilitates ongoing optimization. Striking the right balance between batch size and processing time is key to avoiding unnecessary complexity. In essence, batch processing serves as a strategic tool for enhancing efficiency, provided it is implemented with careful consideration of quality, flexibility, and balance.
3. Key Takeaways: 
   Efficiency Through Grouping: Similar tasks are grouped and processed together, reducing context switching and increasing operational efficiency.
   Reduced Setup and Transition Times: Performing similar tasks in succession minimizes repeated preparation or configuration steps.
   Improved Resource Utilization: Consolidated work allows for better planning and allocation of staff, systems, or tools.
   Scalability with Caution: Larger batches can improve throughput but require careful calibration to avoid delays or quality risks.
   Balance Between Speed and Flexibility: While batching increases speed, it may reduce the system's responsiveness to individual or urgent cases if not managed properly.
4. Performance considerations: The impact of batch processing on performance is analogous to getting more value from your efforts. By concentrating on one batch at a time rather than switching between various tasks, the approach not only accelerates task completion but also optimizes resource utilization. This results in cost savings and improved overall efficiency. Imagine handling paperwork more swiftly and being better equipped to adapt to changing workloads—this exemplifies the positive performance impacts of batch processing.

Cost-based task assignment

1. Definition: Delegate tasks according to resource cost Assign tasks based on the cost of a resource, defined as the person’s per-hour cost when executing a task
2. Description: This heuristic focuses on minimizing process execution costs by assigning tasks to resources based on their hourly rate. The goal is to ensure that tasks are performed by the least expensive capable resource, without compromising quality. For instance, routine administrative tasks should be performed by junior staff rather than highly paid specialists. By aligning task complexity with resource cost, organizations can achieve a more cost-effective distribution of work. However, this approach requires an accurate understanding of task requirements, resource capabilities, and cost structures. It also demands attention to workload balance and employee motivation—repetitive task assignments based purely on cost can lead to dissatisfaction or underutilization of higher-skilled staff.
3. Key Takeaways:
   Cost Efficiency: Tasks are completed by the least expensive qualified resource, reducing overall process costs.
   Capability-Cost Alignment: Resources are matched to tasks based on both cost and skill requirements.
   Avoid Overqualification Waste: High-cost resources are reserved for complex or high-impact tasks.
   Data-Driven Assignment: Requires visibility into resource rates and task complexity.
   Potential Motivation Risks: Over-reliance on cost factors can reduce flexibility and affect team morale.
4. Performance Considerations: By optimizing who performs which task, organizations can significantly reduce labor costs across processes. This approach is especially effective in high-volume, standardized workflows where clear distinctions between task types exist. However, short-term gains must be weighed against long-term implications such as decreased job satisfaction or missed opportunities to develop junior staff through exposure to more complex tasks. Additionally, strict cost-based assignment may reduce responsiveness in dynamic environments if flexibility is not built into the system.

Deploy extra resources

1. Definition: If capacity is insufficient, consider increasing the available number of resources Allocate more people to a task in a process for strategic reasons, such as speeding up the process or reacting to trends
2. Description: This straightforward heuristic speaks for itself. Note the contrast of this heuristic with the numerical involvement pattern. Example: When launching a new product, increase the number of customer service agents available to handle customer inquiries and support requests to ensure timely and efficient service and enhance the customer experience. Implementation: For increased resource assignment, details related to expertise, preference, role, workload, productivity, the collaboration of resources, and constraints in process execution need to be known. Based on the needs of the process, additional resources will be matched and allocated to the process.
3. Key Takeaways: 
   Increased Throughput: More resources allow parallel handling of cases, reducing waiting and processing times.
   Scalable Response to Demand: Enables dynamic adaptation to workload peaks or external trends.
   Improved Flexibility: With more staff, tasks can be reassigned more flexibly across roles.
   Requires Coordination: Effective use of extra resources depends on proper allocation and collaboration mechanisms.
   Cost-Impact Balance: Additional resources improve performance but come with financial and managerial overhead.
4. Performance considerations: The obvious effect of extra resources is that there is more capacity for handling cases, in this way reducing queue time. It may also help to implement a more flexible assignment policy. Of course, hiring or buying extra resources has its cost.

Eliminate activities

1. Definition: Eliminate unnecessary activities Eliminate non-value adding practices
2. Description: A common way of regarding a activity as unnecessary is when it adds no value from a client's point of view. Typically, control activity in a workflow do not do this; they are incorporated in the model to fix problems created or not elevated in earlier steps. Control activities can often be found back as iterations and reconciliation tasks.
3. Key Takeaways: 
   Client-Centric Focus: Activities should be evaluated based on the value they provide to the end customer.
   Identify Redundancies: Iterations, approvals, and reconciliation steps are often signs of inefficiency.
   Less Is More: Streamlining processes by cutting unnecessary tasks improves clarity and execution speed.
   Quality vs. Simplicity Trade-off: Removing control steps may reduce complexity but also eliminate safeguards.
   Requires Careful Analysis: Not all non-value-adding activities are expendable—some may serve critical internal functions.
4. Performance considerations: The aims of this heuristic are to increase the speed of processing and to reduce the cost of handling a case. An important drawback may be that the quality of the service deteriorates.

Establish a case-based mindset

1. Definition: Remove batch-processing and periodic activities from your business process. 
2. Description: This pattern recognizes that practical business processes often deviate from the ideal case-based and make-to-order concepts. It acknowledges the presence of constraints like work item batching and periodic activities that rely on specific computer system availability. These constraints can hinder the efficient handling of cases and impede process performance. By applying this pattern, organizations can strive to remove these constraints and align their business processes more closely with the case-based approach. This entails eliminating the piling up of work items in batches and finding alternatives to periodic activities that rely on specific system availability. The goal is to create a more streamlined and efficient process where cases can be handled promptly and without unnecessary delays. To understand how this pattern can be enacted in an example process, let's consider a customer support system in an e-commerce company. Currently, the support team receives customer queries in batches and processes them in bulk, leading to delays in response times and potential customer dissatisfaction. The periodic activities, such as generating automated reports or system updates, are performed at fixed times, causing further delays in case resolution.
   By introducing the case-based work pattern, the company can transition to a more efficient and responsive process. They can implement an automated ticketing system that assigns individual cases to support agents as soon as they arrive. This eliminates the need for batch processing and ensures timely attention to each customer inquiry.
   Additionally, the company can leverage technology to remove constraints related to periodic activities. For example, instead of relying on specific system availability for generating reports, they can implement real-time reporting dashboards that are accessible to agents at any time. This enables them to access up-to-date information and resolve cases promptly, without being dependent on specific processing windows.
   Through the adoption of the pattern, the customer support process becomes more streamlined, cases are handled promptly, and customer satisfaction improves. The removal of constraints allows for more agility and responsiveness, resulting in a more efficient and effective support system.
3. Key Takeaways:
   1. Address Constraints The pattern aims to eliminate constraints such as work item batching and reliance on periodic activities tied to specific computer system availability.
   2. Speed up Case Handling By removing these constraints, the pattern can significantly improve the efficiency and speed of case handling.
   3. Consider Efficiency vs. Cost While eliminating constraints may enhance case handling, it is crucial to evaluate the trade-off between the benefits of streamlined processes and the potential costs involved.
4. Performance considerations: Switching to case-based work can have significant performance implications on the overall process. By eliminating work item batching, cases can be handled more swiftly, reducing delays and improving customer satisfaction. Removing reliance on specific system availability for periodic activities ensures that tasks can be performed consistently, avoiding bottlenecks caused by limited processing windows. However, it's important to consider the trade-off between efficiency and cost. While streamlining the process and removing constraints can enhance case handling, it may require investments in infrastructure, technology, and system availability. Organizations need to assess the potential financial implications and weigh them against the benefits gained in terms of improved efficiency, customer experience, and overall process performance

Experience-based task assignment

1. Definition: Delegate task according to experience: execution frequency, case involvement, interactions Assign a task to a person based on their experience, measured by the number of times they have executed a work item, been involved in a case, and interacted with others.
2. Description: Example: An organisation assigns a senior manager role in data and analytics to a person with at least 10 project involvements, five project leadership experiences, and team management experience of at least 20 people. Implementation: Experience metrics for people must be available. At the time of execution, the experience required for the task will be matched with existing data and to select an appropriate person.
3. Key Takeaways: 
   Improved Quality: Tasks are handled by individuals with proven expertise, reducing errors and rework.
   Faster Execution: Experienced individuals complete tasks more efficiently due to familiarity and confidence.
   Data-Driven Allocation: Assignment decisions are based on measurable experience rather than assumptions or titles.
   Retention of Tacit Knowledge: Promotes leveraging internal know-how and continuity within teams.
   Requires Skill Tracking Infrastructure: Accurate task-to-resource matching depends on reliable experience data.
4. Performance considerations: This pattern will result in high-quality outcomes in less time.

Fail Early

1. Definition: Order knock-outs by least effort and highest termination probability first. Prioritize checking conditions that balance high termination probability and low effort to minimize cost and maintain efficiency.
2. Description: The knock-out pattern is a strategic and practical approach to improving operational efficiency. At the core of a typical business process are numerous conditions that must be met to achieve a desired outcome. However, if any of these conditions fail, it could lead to a premature termination of the process segment, termed a 'knock-out'. This pattern works by analyzing and sequencing the order in which these conditions are checked. The flexibility in this ordering allows for a smart strategy where the conditions with the most favorable balance of high termination probability and low effort are checked first, followed by the second most favorable, and so on.
   In other words, we aim to verify the conditions most likely to fail and least costly to check before the others. This methodical ordering minimizes the overall cost and effort of executing the business process by terminating any potentially unsuccessful paths at the earliest stage. It's important to note that implementing the knock-out pattern requires a level of autonomy in the ability to order these checks. Also, while this approach generally leads to cost-efficient processes, it might potentially increase the total time taken to complete the process compared to simultaneous verification of all conditions. This is a factor to consider based on the specific needs and constraints of your business process.
3. Key Takeaways: 
   1. Try to fail cheap and early Sequential checking of conditions, prioritizing those with higher knockout probability and lower checking effort, often leads to cost-efficient business processes.
   2. Flexibility required Application might be limited in scenarios where the conditions' verification order cannot be freely modified.
   3. Cost vs. Time While this approach optimizes cost, it might extend the total process duration compared to a parallel verification of all conditions.
4. Performance considerations: Adopting this sequential checking strategy usually leads to the most cost-effective operation of a business process on average. While there isn't any clear downside to this approach, its application might be limited in scenarios where the order of checks can't be freely adjusted. Furthermore, while this method optimizes cost, it may prolong the total processing time in some parts of the workflow, compared to a scenario where all conditions are verified simultaneously.

Generalize your process

1. Definition: Explore whether a process can easily be used for additional products or services. Process generalization involves repurposing a procedure to efficiently create fresh value through the cost-effective delivery of novel products or services to the market.
2. Description: Process generalization aims to broaden the applicability of a given process by removing product-specific elements or creating modular structures. Instead of designing processes for a single product, the organization builds flexible workflows that support multiple product lines or service variants. This can significantly reduce time-to-market for new offerings, enable reuse of existing capabilities, and support scaling.
   Example: A bank redesigns its loan approval process to work not only for personal loans but also for small business and car loans, by abstracting steps like risk assessment, document verification, and approval routing. Key to implementation is identifying core tasks shared across variants and isolating those that require product-specific handling.
3. Key Takeaways:
   Scalability and Flexibility: A generalized process supports a broader set of offerings with minimal changes.
   Faster Time-to-Market: Reusing core processes accelerates deployment of new products or services.
   Efficiency Through Standardization: Common tasks are unified, reducing duplication of effort.
   Modularity Is Key: Generalization often requires separating generic from product-specific logic.
   Needs Strong Governance: Without careful management, generalized processes can become overly complex or vague.
4. Performance considerations:
   Generalizing a process reduces design and operational costs across product lines by maximizing reuse. It also improves responsiveness to market opportunities and customer demands. However, overly generic processes may suffer from a lack of optimization for specific use cases, leading to inefficiencies or reduced service quality. The challenge lies in striking a balance between flexibility and performance.

Green Feature

1. Definition: Let products appear greener
2. Description: Organizations gain a reputation of being green when they have at least a few outstanding green features in their products. A single feature may only contribute marginally to the overall ecological impact of their product. However, the combination of several different green features may significantly influence the environmental impact. Challenges: Determine eye-catching features of a product which can be altered to be greener.
3. Implementation: Identify all features of a product where a green alternative might be available. Replace those features with a greener alternative for which the greener alternative is reasonable from an economical point of view. One selection criterion should be the fact that it is easy to communicate to customers. Thus, this green feature can be used to attract the attention of the customers distracting from other less green features of the product. Results:  A product which looks very ecofriendly to the customer although the impact of the green features of the product may only decrease the ecological footprint a little. Example:  An enterprise may advertise a production plant by showing a production process to the customers. This production process contains certain green features mentioned prominently, like specific activities which are executed on environmentally friendly machines. However, the remaining process is performed in a conventional way. Another example is the production of outdoor clothes. Most companies use the environmentally harmful fluorocarbon within the manufacturing process. Changing the manufacturing to be fluorocarbon free is a feature that can be used as competitive advantage compared to production of regular outdoor clothes. A similar example comes from the food industry. A lot of beverages come in plastic bottles made from polyethylene terephthalate. A company in Europe adds specific syrup originating from sugar production to their bottles which reduces the share of polyethylene terephthalate. Variations: Repeated application of this pattern may lead to a product comprising only of features considered green. In this case the products impact on the environment is improved even more. Another variant could be the environmental certification of specific features without changing them explicitly. Relations to other Patterns This pattern is closely related to Use Eco-friendly Resources. Depending on the type of the business process the exchange of resources can be a multiplier to increase the impact on the perception of the customers.
4. Key Takeaways:
   Perception-Driven Impact: Even small changes can significantly influence how eco-friendly a product appears to customers.
   Incremental Strategy: A few well-communicated green features can pave the way for broader sustainability transformations.
   Marketing Advantage: Easily understood green elements can serve as differentiators in competitive markets.
   Trade-off Awareness: Improvements in perception may not always reflect actual ecological benefits.
   Repeatable Pattern: Can be gradually expanded to fully transform products and enhance environmental credibility.
5. Performance Considerations:
   The primary benefit of this pattern lies in improving the external perception of sustainability, which can boost customer appeal and brand reputation. However, the actual environmental performance gains may be limited if only a few superficial features are modified. Economic viability and ease of communication are key factors for successful implementation. Overuse without substance may lead to accusations of greenwashing, negatively affecting credibility.

Human Process Performance

1. Definition: Consider whether it is eco-friendly to let humans work over machines
2. Description: Organizations are based on both human and IT supported activities and processes that aim to achieve a certain strategic objective. These activities need to be organized in such a way that organizations are most profitable and reach certain ecological goals within a given environment. Performing some activities by human workers can be one possibility to reach this objective. 
   Challenges: Determining activities in a workflow which may be replaced by human activities to improve the ecological footprint of a certain business process. 
   Solution:  Replace certain activities which are enacted by machines that pollute the environment with human performed activities to obtain a greener business process.
   Results: By replacing certain activities of a workflow so that they are enacted by humans, the environmental impact of a business process may be reduced.
   Example: Consider an organization that manufactures specialized metal parts for engineering. The parts are produced in small batch series. Instead of using a high-tech laser-scanning machine which scans each part for quality assurance, an employee checks the corresponding part. This saves the organization costs (at least to some extend) and decreases the environmental impact which is created through the manufacturing and operation of such a specialized machine. 
   Variations: Single activities must not be executed by humans in total. They can also be semi-automated or split into an automated and a manual part to better (i.e. more efficiently) support human process performance. Relations to other Patterns: The green automatization pattern may be considered as the opposite of the Human Process Performance pattern. Also, the use eco-friendly resources pattern may be considered because changing an activity to be enacted automatically may be considered the same as using other resources to enact a certain task.
3. Key Takeaways: 
   Human-in-the-Loop as a Green Strategy: Substituting machines with human labor can reduce energy consumption and emissions.
   Selective Replacement: Not all automated tasks need to be replaced—focus on high-impact machine processes.
   Balancing Cost and Impact: In some cases, human execution may be both cheaper and greener, especially in low-volume or specialized tasks.
   Hybrid Options: Partial automation or manual support can offer the best of both worlds in terms of efficiency and sustainability.
   Strategic Workforce Role: Reframing humans as sustainability enablers can also enhance workforce value and motivation.
4. Performance considerations: 
   Replacing machine-based tasks with human labor can lower environmental impact, particularly when machines require significant energy or emit pollutants. However, this shift must consider labor costs, scalability, and process efficiency. Manual tasks may introduce variability or slower execution but can be preferable in small-scale, custom, or ecologically sensitive contexts. Organizations should evaluate whether the ecological gains justify potential trade-offs in consistency or speed.

Minimize numerical involvement

1. Definition: Too many cooks spoil the broth This pattern suggests reducing the number of individuals involved in executing a task or case to avoid unnecessary handovers, miscommunication, and coordination overhead.
2. Description:
   In many processes, multiple individuals may be involved in completing a single case, especially when tasks are divided too granularly or when responsibilities are unclear. This often leads to excessive coordination, longer cycle times, and potential quality issues due to handovers and misunderstandings. By minimizing the number of people involved, organizations can streamline communication, reduce delays, and increase accountability.
   Example: Instead of having three different departments handle various approval steps in a procurement process, a single cross-trained employee is assigned to manage the end-to-end case. This reduces back-and-forth and speeds up execution.
   This pattern often works hand in hand with role consolidation and case ownership concepts.
3. Key Takeaways:
   Fewer Handovers: Reduces delays, misunderstandings, and quality issues related to task switching and rework.
   Increased Accountability: Clear ownership encourages responsibility and follow-through.
   Simplified Coordination: Fewer people involved means fewer dependencies and communication loops.
   Cross-Training May Be Required: Consolidation of roles can require skill broadening.
   Supports End-to-End Thinking: Promotes holistic understanding of the process rather than fragmented task execution.
4. Performance considerations:
   Minimizing numerical involvement can significantly reduce throughput time and coordination costs. It also fosters consistency in execution and improves customer experience through fewer touchpoints. However, it may place higher demands on individual workers and can create single points of failure if not managed carefully. Balancing workload and ensuring adequate skill coverage are critical for sustainable application.

Offer location flexibility

1. Definition: Let customers interact with the company wherever they want to.
2. Description: Rather than confining engagement to specific physical locations, organizations must embrace a customer-centric approach by designing business processes that empower customers to choose where and how they interact, regardless of the organization's office or branch locations. By granting customers the freedom to determine the interaction setting, companies can foster a seamless and personalized experience, nurturing stronger connections and driving business growth. Companies should not restrict their interactions with customers to distinct physical locations. Instead, business processes should be designed such that customers can decide themselves where interactions take place, regardless of the location of the organization’s offices or branches. Real-world application: Nextbike enables renting bicycles in large cities. Unlike other providers, bicycles can be rented and returned not only at specific stations but also in so called flex zones, i.e. on public roads. This allows customers to arrive close to their destination even though there is no nextbike station. Selected source. 
3. Key Takeaways:
   Customer Empowerment: Users choose where and how they interact, increasing convenience and satisfaction.
   Decentralized Service Access: Reduces reliance on fixed infrastructure like branches or stations.
   Enhanced Process Reach: Location-flexible processes extend the service's geographical and demographic reach.
   Digital Enablers Often Required: Successful implementation usually relies on mobile apps, GPS, or cloud-based services.
   Supports Omnichannel Strategy: Encourages integration of physical and digital interaction points.
4. Performance considerations:
   1. Location flexibility supports three major performance enablers:
   2. Individuated Interaction Capability: Customers can tailor the interaction context to their preferences (e.g. at home, in transit).
   3. Empowered Interaction Capability: The organization gives users control over where and when they engage with the process.
   4. Concerted Interaction Capability: Seamless integration across channels and locations allows consistent experience and coordination.
   5. These effects contribute to improved customer satisfaction, higher engagement, and potentially lower operational costs due to reduced dependency on physical locations. 

Outsource activities

1. Definition: Delegate and optimize your operations A strategy of entrusting specific business activities to external service providers for cost savings and enhanced focus on core competencies.
2. Description: Outsourcing of Business Activities is a strategic approach in which organizations delegate certain non-core business activities to external service providers. This pattern enables companies to streamline their operations, reduce costs, and increase efficiency by leveraging the expertise and economies of scale offered by specialized outsourcing partners. By outsourcing non-core functions, organizations can free up internal resources, allowing them to concentrate on their core competencies and strategic initiatives. Outsourcing of Business Activities offers several advantages. Firstly, it allows companies to access specialized skills and knowledge that may not be readily available in-house, leading to improved service quality and productivity. Secondly, outsourcing often leads to cost savings through reduced labour, infrastructure, and operational expenses. Additionally, outsourcing providers can offer scalability and flexibility, allowing businesses to quickly adapt to changing market demands. It is crucial, however, to carefully select and manage outsourcing partners to ensure alignment with business goals and maintain effective communication and collaboration.
3. Key Takeaways:
   Focus on Core Competencies: Enables internal teams to focus on strategic and value-creating activities.
   Cost Savings Potential: Reduces expenses related to labor, infrastructure, and overhead.
   Access to Expertise: Leverages capabilities and tools of specialized providers.
   Scalability and Flexibility: Outsourced services can adapt more quickly to demand fluctuations.
   Requires Oversight: Ongoing vendor management is critical to maintain quality and alignment.
4. Performance considerations:  The primary objective of outsourcing tasks is to reduce costs and optimize resource allocation. However, it may come at the expense of reduced control and potentially lower service quality. Moreover, outsourcing introduces additional coordination and communication overhead. If not carefully managed, this can offset the intended efficiency gains and lead to workflow fragmentation. Establishing clear SLAs (Service Level Agreements), communication protocols, and performance monitoring is essential to mitigate these risks.

Performance-based task assignment

1. Definition: Allocate tasks based on past performance: execution time and success Assign tasks based on a person’s past performance, measured by execution time and successful outcomes.
2. Description: This pattern proposes assigning tasks to individuals who have demonstrated superior performance in executing similar tasks in the past. Performance is typically measured by key indicators such as speed, error rates, output quality, and customer satisfaction. By systematically matching tasks with high-performing individuals, organizations can increase overall process efficiency and reliability.
   Example: In a customer service process, support tickets with high priority or complexity are assigned to agents with a track record of quick resolution times and high customer ratings. This improves service levels while also recognizing and utilizing internal talent.
   For implementation, accurate tracking and analysis of individual task performance is required, which may involve data collection via workflow systems, dashboards, or performance monitoring tools.
3. Key Takeaways:
   Optimized Task Execution: Assigning tasks based on proven performance ensures higher efficiency and quality.
   Data-Driven Decisions: Task allocation is grounded in measurable metrics, not assumptions.
   Talent Utilization: High performers are consistently deployed where they deliver the most value.
   Performance Feedback Loop: Promotes a culture of continuous improvement and transparency.
   Avoids One-Size-Fits-All: Tailors task distribution to individual strengths rather than equal distribution.
4. Performance considerations:
   When executed effectively, this pattern leads to shorter processing times, fewer errors, and higher customer satisfaction. However, it can also lead to overburdening top performers and demotivating others if not carefully balanced. There is also a dependency on reliable and fair performance metrics—biased or incomplete data can lead to poor decisions. Organizations must complement this pattern with strategies for workforce development and rotation to avoid burnout and skill stagnation.

Tailored privacy settings

1. Definition: Offer customers the possibility to choose among privacy settings
2. Description: Companies need to show customers that they really care about their privacy. They can do this by telling people about their privacy rules or by letting customers set their own privacy preferences, even if it goes beyond what the law requires. For instance, customers should be able to choose different levels of privacy before and during using a service. It's also important for companies to explain how these privacy choices might affect the service and how customers experience it. This means some features might not work if you have very strict privacy settings.
3. Key Takeaways:
   Customer Empowerment: Allows individuals to control how their data is used.
   Trust and Transparency: Builds credibility by openly communicating data usage and options.
   Differentiated Experience: Enables customers to tailor the balance between privacy and service richness.
   Regulatory Proactivity: Goes beyond minimum legal standards, fostering goodwill and future-proofing compliance.
   Requires Clear Communication: Customers need to understand trade-offs between privacy levels and available features.
4. Performance considerations: Allianz allows customers to choose whether they want to release the doctor from the obligation of confidentiality for one specific issue or for all prospective issues. This way, customers can decide themselves how much details of their health records Allianz may access. Deutsche Bank offers its customers benchmarking services for personal expenses in case they grant access to own data.

Quality-based task assignment

1. Definition: Allocate task based on past feedback or quality metrics. Assign a task based on prior internal or external customer feedback or quality metrics. 
2. Description: Example: An organisation evaluates the performance of its customer service representatives based on customer feedback and assigns high-performing representatives to handle complex customer complaints.  Implementation:  For quality-based task assignments, details related to the customer evaluation feedback for resources need to be known. At the time of allocation, people with the best quality feedback will be chosen for the task.
3. Key Takeaways:
   Customer-Centric Allocation: Task distribution is guided by customer satisfaction and service quality.
   Focus on Outcome Excellence: Ensures that critical tasks are handled by those with a proven track record of quality.
   Supports Continuous Improvement: Encourages individuals to maintain or improve performance over time.
   Reinforces Accountability: Performance feedback becomes actionable in task assignment.
   Feedback as Strategic Asset: Turns qualitative and quantitative evaluations into operational input.
4. Performance considerations: 
   This pattern aims to ensure consistently high-quality outcomes by assigning work to individuals with strong feedback histories. It improves customer satisfaction and service reliability. However, over-reliance on a few top performers may cause workload imbalances or burnout. Fairness and transparency in the feedback and evaluation mechanisms are essential for long-term success.

Resequence activities

1. Definition: Move activities to more appropriate places .
2. Description: The current sequencing of tasks in existing workflows may not fully reflect the logical constraints that need to be observed between tasks. As a result, it can occasionally be advantageous to delay a task, particularly if it is not necessary for tasks that immediately follow. By doing this, there's a chance that the task may turn out to be unnecessary, leading to cost savings. Moreover, positioning a task closer to another task of a similar nature can potentially reduce setup times. Examples of these resequencing strategies include the knock-out heuristic, control relocation, and the parallelism heuristic. Flowchart Left to Right: start(start)-->3-->1-->2-->fin(end)
3. Key Takeaways:
   Avoid Unnecessary Work: Postponing non-critical tasks may render them obsolete if earlier criteria disqualify the case.
   Reduce Setup and Transition Time: Grouping similar tasks can improve efficiency.
   Enable Parallel Processing: Resequencing allows better exploitation of concurrent task execution.
   Optimize Control Placement: Control tasks can be more effective when timed appropriately.
   Process Logic First, Tradition Second: Resequencing challenges legacy task orders that no longer serve performance goals.
4. Performance considerations: 
   Resequencing can significantly improve throughput, reduce resource consumption, and prevent wasted effort on tasks that may ultimately be unnecessary. It increases process agility and adaptability, particularly when used in combination with early decision-making or automation. However, dependencies and compliance constraints must be carefully considered to avoid logic errors or violations of required process order.

Shift Workload

1. Definition: Execute tasks when the grid is powered by renewable energy
2. Description: The basic idea behind the time shifting approach is moving the computing load into a point in time when the power grid has a maximum of renewable energy. This will result in a lower emission of CO2 of a computing task. 
   In addition to energy and hardware efficiency, carbon efficiency is one of the most important principles of green software development, like the Energiewende. Energy is used when it is available from renewables. Implementation: We shift the energy demand to a point in time when the carbon intensity of the grid is lower. To do this we need forecast data and software libraries to calculate the appropriate execution window.
3. Key Takeaways:
   Carbon-Aware Scheduling: Aligns workload execution with times of low carbon intensity.
   Forecast-Driven Logic: Requires grid data and predictive models to schedule smartly.
   Suitable for Non-Critical Loads: Best applied to tasks that can tolerate flexible timing.
   Supports Sustainability Goals: Contributes directly to lower carbon footprints in IT operations.
   Part of Broader Green IT Strategy: Complements other approaches like green hardware and efficient coding.
4. Performance considerations:
   Shifting workload to greener time slots can dramatically reduce the environmental impact of IT systems, especially in energy-intensive tasks such as machine learning training or data processing. While it may introduce delays in execution, these are often acceptable for non-real-time workloads. The effectiveness of this approach depends on access to reliable carbon intensity forecasts and the technical flexibility to defer or reschedule tasks. Organizations that implement carbon-aware workload shifting can also benefit reputationally by aligning with ESG (Environmental, Social, Governance) objectives.

Split responsibilities

1. Definition: Avoid shared responsibilities for tasks by people from different functional units . 
2. Description:
   The idea behind this redesign pattern is that tasks for which different departments share responsibility are more likely to be a source of neglect and conflict. When multiple units are jointly accountable, it becomes unclear who should act, leading to delays, inconsistent execution, or finger-pointing in case of errors. By assigning clear, unit-specific ownership for each task, organizations can reduce ambiguity, strengthen accountability, and improve task execution quality.
3. Key Takeaways:
   Clear Ownership: Each task has a defined owner, reducing ambiguity and improving accountability.
   Fewer Coordination Delays: Eliminates the back-and-forth between departments over shared duties.
   Improved Task Quality: Focused responsibility encourages deeper engagement and higher precision.
   Reduces Conflict Potential: Clarifies roles and expectations, preventing disputes.
   Works Best with Well-Defined Interfaces: Task handoffs must be clearly structured between units.
4. Performance considerations: 
   Reducing the overlap in responsibilities should lead to a better quality of task execution. A higher responsiveness to available work items may be developed also, so that clients are served quicker. On the other hand, reducing the effective number of resources that is available for a work item may have a negative effect on its throughput time, as more queuing may occur.

Teamwork-based assignment

1. Definition: Allocate task based on collaborative experience: handover time, interactions, diversity. Assign a task to a person based on their experience working with other resources, which is measured by factors such as the time taken for handovers, number of interactions, and diversity of experience with different people.
2. Description: Example: The review risk task in a loan application process requires two resources to work together. The task is hence allocated to resources A and B as they have evidenced working well together in the past. Impact: This pattern will result in a high-quality outcome in less time and cost. Implementation: For a teamwork-based assignment, a prior understanding of the interaction of a resource with other resources needs to be known. Based on that understanding, appropriate resources will be allocated
3. Key Takeaways:
   Improved Coordination: Assignments are optimized for working relationships, reducing friction and delays.
   Higher Quality Outcomes: Teams that collaborate well tend to produce better results.
   Reduced Handover Time: Familiarity and mutual understanding speed up joint work.
   Data-Driven Team Formation: Assignments are based on actual past collaboration patterns.
   Encourages Stable Working Pairs or Groups: Builds long-term cooperation and trust within the workforce.
4. Performance considerations: 
   This pattern will result in a high-quality outcome in less time and at lower cost. By leveraging existing relationships and communication efficiency, teamwork-based assignments reduce coordination overhead and improve process flow. However, care must be taken to avoid over-reliance on recurring pairs, which could reduce flexibility and hinder knowledge diffusion across the organization.

Work in customer teams

1. Definition: Form cross-department teams for end-to-end case handling. Compose work teams of people from different departments that will take care of the complete handling of specific sorts of cases.
2. Description: Customer teams are an advantageous method that brings together employees from various departments to handle specific types of process instances or cases. The primary responsibility of the team is to oversee a case, with individual members not necessarily involved in executing the case itself. This collaborative approach allows for easy access to shared and distributed knowledge, departmental resources, and tools, enabling a comprehensive examination of a case from multiple perspectives. By utilizing customer teams, organizations can enhance their problem-solving capabilities and provide more efficient and effective resolutions for their customers.
3. Key Takeaways:
   Cross-Functional Collaboration: Teams consist of members from different departments, breaking down silos.
   Holistic Case Management: Customer teams oversee the case from start to finish, ensuring continuity.
   Better Use of Expertise: Combines diverse skills and perspectives to handle complex or varied cases.
   Shared Accountability: Responsibility is distributed across the team rather than isolated in roles.
   Enhanced Knowledge Sharing: Fosters better communication and learning across departments.
4. Performance considerations: In summary, customer teams offer a valuable solution for efficiently handling specific cases. By implementing this pattern, organizations can tap into the expertise of multiple workers while also promoting teamwork and enhancing overall quality.

Apply triage

1. Definition: Consider the division of a general activity into two or more alternative activities Create two (or more) variants of activities.
2. Description: A special form of the triage heuristic is to divide a task into similar instead of alternative tasks for different subcategories of the case type. For example, a special cash desk may be set up for clients with an expected low processing time. The triage heuristic is related to the task composition heuristic in the sense that it is concerned with the division and combination of tasks. Note that the heuristic differs from it in the sense that alternative tasks are considered.
3. Key Takeaways:
   Path Differentiation: Splits one activity into alternative variants based on case type or complexity.
   Resource Matching: Enables better alignment of task difficulty with employee skill levels.
   Improved Efficiency: Fast-track cases can be completed more quickly, reducing overall throughput times.
   Supports Specialization: Tasks become more focused, allowing deeper expertise in each variant.
   Flexible Interpretation: The heuristic can be applied both to similar and alternative task paths, depending on use case.
4. Performance considerations: When applying the pattern in its main form, it is possible to design tasks that are better aligned with the capabilities of resources and the characteristics of the case. Both improve the quality of the workflow. Distinguishing alternative tasks also facilitates a better utilization of resources, with obvious cost and time advantages. On the other hand, too much specialization can make processes become less flexible, less efficient, and cause monotonous work with repercussions for quality. This is lifted by the alternative interpretation of the triage heuristic.

Assign cases

1. Definition: Let workers perform as many steps as possible for single cases.
2. Description: A case manager plays a crucial role in overseeing a case, but they are not necessarily involved in carrying out the entire workflow. To ensure efficient coordination, the process of assigning cases can be utilized. This involves selecting a resource who has previously worked on the case and can perform the necessary tasks. Rather confusingly, this person is sometimes also referred to as case manager. 
3. Key Takeaways: 
   Continuity of Work: One person handling multiple steps ensures consistency and familiarity with the case.
   Reduced Setup Time: Fewer handovers lead to less context-switching and quicker task initiation.
   Improved Service Quality: Familiarity with the case can enhance responsiveness and customer experience.
   Supports Ownership Thinking: Encourages accountability and follow-through.
   Trade-off with Flexibility: Ties cases to individuals, which may reduce load-balancing options.
4. Performance considerations: The obvious advantage of the rule is that this person will get acquainted with the case and will need less set-up time. An additional benefit may be that the quality of service is increased. On the negative side, the flexibility of resource allocation is seriously reduced. A case may experience substantial queue time when its "case manager" is not available.

Automate for environmental impact

1. Definition: Implement automation in a sustainable way.
2. Description: Business processes are based on both human and IT supported activities that aim at achieving a certain strategic objective. These activities need to be organized in such a way that organizations are most profitable and ecological goals within a given environment can be met. Rationalizing some activities is one possibility to reach this objective.
3. Key Takeaways: The identification of activities that can be automated can be a challenging task. The automated activity needs to perform the task in such a way that either the result remains the same or is even improved or the costs are getting much lower. In the latter case the trade-off between the environmental impact, the costs, and the expected quality needs to be addressed in detail. It must further ensure the global integration with other activities that are dependent on that activity. Solution; Organizations (partially) streamline specific activities within a business process by automating them. Example; A telecommunication company needs to send its customers an invoice for their connections every month. Usually, the invoices are sent to the customers via mail. Now, the company changes the charging process and transmits the information directly and fully automated to the customers via e-mail. This process restructuring saves time, cost, and in particular decreases the environmental impact caused by the paper manufacturing, the invoice printing, and the transport of the delivery company. Variations; Single activities must not be totally automated. They can also be semi-automated or split into an automated and a manual part to better (i.e. more efficiently) support human process performance. This pattern is strongly related to Human Process Performance as it covers the contrary situation. Depending on the structure of the business process, both patterns can be used to ecologically optimize processes on an activity changing basis.
4. Performance considerations: The automatization of specific process activities provides the means for optimizations from both, a regular and an ecological perspective. Time, quality, and costs can be improved while energy consumption can be reduced, for example.

Combine activities

1. Definition: Combine small activities into composite activities. A technique for combining smaller tasks into larger ones to reduce setup times and improve the quality of work.
2. Description: Task Combination is a process optimization technique that involves combining smaller tasks into larger ones. This technique reduces setup times, which are the time that resources need to become familiar with the specifics of a case and can improve the quality of work. However, it is important to strike a balance between the size of the tasks and their workability. Tasks that are too large can result in smaller run-time flexibility and lower quality. Smaller tasks, on the other hand, can result in longer setup times.
3. Key Takeaways: 
   Reduced Setup Effort: Fewer task switches and less need for case re-familiarization.
   Improved Quality: Larger task scopes allow for more holistic handling and reduce fragmentation.
   Fewer Handovers: Combining tasks cuts down on coordination points and transition errors.
   Workload Stability: Composite tasks can be better aligned with individual roles or work packages.
   Balance Required: Over-combining may reduce flexibility and overburden resources.
4. Performance considerations: 
   By finding the optimal balance, organizations can achieve the best of both worlds: shorter setup times, higher quality, and greater flexibility. Properly sized composite tasks reduce waste caused by frequent context switching and improve continuity. However, excessive task bundling may reduce the ability to quickly reallocate or parallelize work, especially in dynamic environments.

Constraint-based task assignment

1. Definition: Allocate tasks considering business process execution constraints. Assign tasks to resources based on constraints associated with the execution of tasks within the business process. 
2. Description: Constraint-based task assignment refers to the allocation of tasks while taking into account various predefined constraints that influence task execution. These constraints can include factors such as legal or compliance requirements, temporal restrictions (e.g. deadlines or time windows), resource availability, segregation of duties, or required qualifications. The aim is to ensure that tasks are executed in a way that respects all operational, regulatory, or business rules.
   Example: In a financial approval process, tasks requiring sign-off above a certain threshold must be handled by a certified senior manager. Or in healthcare, certain tasks may only be assigned to personnel with a valid medical license.
   Effective implementation requires a clear definition of constraints and the integration of these rules into the task allocation logic, often via workflow engines or rule-based systems.
3. Key Takeaways:
   Compliance Assurance: Helps ensure that legal, regulatory, or policy-related conditions are met.
   Reduced Risk: Prevents unauthorized or inappropriate task execution by unqualified resources.
   Rule-Based Allocation: Assignments follow predefined business logic instead of ad hoc decisions.
   Scalable and Auditable: Supports transparent and traceable allocation, crucial for audits.
   Requires Governance: Success depends on clearly defined, maintained, and up-to-date constraint sets.
4. Performance considerations: 
   While constraint-based task assignment promotes correctness and accountability, it may reduce flexibility in task distribution and slow down execution if suitable resources are limited. However, it minimizes rework, compliance violations, and operational risk—leading to long-term gains in reliability and quality. Automation of constraint checks can mitigate performance trade-offs by accelerating decision-making.

Department-based assignment

1. Definition: Distribute tasks by interdepartmental interactions to enable or restrict involvement. Assign tasks to people based on their interactions with other departments to involve multiple departments or limit involvement.
2. Description: An example, the review loan application task has been assigned to a resource from the finance and human resources departments, as they have shared responsibility. Implementation; For department-based assignments, prior information related to different departments, people in those departments, their skills, and the time involved in handovers may be required. Based on this information and the objective of the process, the appropriate resources would be allocated to the tasks of the process.
3. Key Takeaways: 
   Leverages Departmental Expertise: Allocates tasks to individuals familiar with the relevant department(s).
   Supports Collaboration or Separation: Can be used to foster cross-department work or enforce boundaries.
   Improved Task Alignment: Tasks are handled by people who understand the functional context.
   Increases Role Precision: Reduces ambiguity in responsibilities by assigning based on departmental scope.
   Requires Organizational Visibility: Success depends on up-to-date knowledge of departmental roles and workflows.
4. Performance considerations: 
   This pattern can lead to high-quality outcomes with improved efficiency, especially when departments must coordinate on shared cases. It enables smoother workflows when well-integrated and helps manage complexity through structured responsibility assignment. However, it may also introduce coordination overhead if departments are siloed or communication is weak. Clear interfaces and shared objectives between departments are critical for optimal performance.

Distinguish case types

1. Definition: Determine whether activities are related to the same type of case and, if necessary, distinguish new business processes.
2. Description: One should be cautious of parts of business processes that are not specific for the business process they are part of. Ignoring this phenomenon may result in a less effective management of such a sub-process and a lower efficiency. Applying this heuristic may result in faster processing times and less cost. Ignoring this phenomenon may result in a less effective management of this "subflow" and a lower efficiency. Note that this heuristic is in some sense like the triage concept. The main interpretation of the triage concept can be seen as a translation of the case type pattern on an activity level.
3. Key Takeaways:
   Clarity Through Segmentation: Separating different case types allows for more targeted and efficient process design.
   Improved Subflow Management: Identifies recurring patterns that may be better managed independently.
   Faster Processing: Enables streamlined paths for simpler or frequently occurring case types.
   Reduced Waste: Avoids forcing all cases through a one-size-fits-all process.
   Foundation for Triage or Specialization: Enables further optimization techniques like parallel paths or fast lanes.
4. Performance considerations: 
   Applying this best practice may yield faster processing times and lower costs by tailoring process paths to distinct case types. It can also improve management of common subflows across multiple processes. However, it may introduce additional coordination overhead between case types, and reduce flexibility for holistic process redesign. Careful process architecture is required to balance segmentation with maintainability.

Empower resources

1. Definition: Empower workers for more decision-making authority. Give workers most of the decision-making authority instead of relying on middle management.
2. Description: In conventional processes, significant time is used to approve others' work. Granting employees autonomy can lead to streamlined operations and quicker workflows.
   Example: To streamline the insurance claim process, resources are empowered to make decisions in place of middle management, reducing approval bottlenecks.
   Implementation: To empower resources, gather information about their capability, productivity, collaboration, and utilization. Based on this information, identify resources capable of making decisions and provide them with the necessary authority. Communicate the reasons behind the empowerment and clarify the expectations and constraints tied to the delegated authority.
3. Key Takeaways:
   Faster Decisions: Reduces delays from hierarchical approval steps.
   Increased Ownership: Workers are more engaged and accountable for outcomes.
   Decentralized Agility: Teams can respond more quickly to dynamic situations.
   Requires Trust and Transparency: Empowerment works best when expectations are clearly defined.
   Not One-Size-Fits-All: Empowerment must be aligned with individual competence and task criticality.
4. Performance considerations: 
   Empowering employees can reduce throughput times and increase motivation, but may result in inconsistent decision quality if not properly supported. In cases where errors occur, the cost of rework or compliance issues may exceed the time saved. Therefore, empowerment should be balanced with support structures like training, clear rules, and escalation paths to ensure quality and control are maintained.

Establish Standardized Interfaces

1. Definition: Consider a standardized interface with customers and partners. A standardized interface diminishes the occurrence of mistakes, incomplete applications, or unintelligible information exchanges. This may yield better quality due to less errors and faster processing time.
2. Description: The concept underlying this heuristic suggests that employing a standardized interface can reduce the likelihood of errors, incomplete submissions, unclear communications, and so forth. The interfacing heuristic can be regarded as a particular interpretation of the integration heuristic.
3. Key Takeaways:
   Error Reduction: Structured inputs minimize the chance of incorrect or missing data.
   Faster Processing: Standardized information is easier to validate and route.
   Improved Interoperability: Facilitates smoother collaboration with external systems and partners.
   Scalability: A single, consistent interface can support high transaction volumes.
   Foundation for Automation: Structured data enables more extensive automation downstream.
4. Performance considerations: 
   A standardized interface may result in fewer errors (improved quality), faster processing times (efficiency), and less rework (cost savings). It enhances process reliability and user experience while reducing the need for manual correction or clarification. However, too rigid an interface may limit flexibility for edge cases, so it should be designed with both standardization and usability in mind.

Expertise-based task assignment 

1. Definition: Match tasks to experts' specialized skills for efficiency. Assign tasks based on the unique skills of the person(s) involved. Expertise is defined as the specialised skills possessed by a resource.
2. Description:
   This pattern involves aligning tasks with the specific technical or domain expertise of individuals. Instead of assigning tasks randomly or based on availability, the system considers who has the most relevant skills to handle a given task. This improves the quality and speed of task execution, particularly in knowledge-intensive or high-risk environments.
   Example: In a software development process, critical security reviews are assigned to team members with certified cybersecurity backgrounds rather than general developers.
   Implementation: Organizations must track and maintain up-to-date skill profiles for their workforce, often through internal competency databases or skill matrices.
3. Key Takeaways:
   Higher Task Quality: Experts are more likely to complete tasks accurately and efficiently.
   Reduced Rework: Specialized knowledge decreases the likelihood of mistakes.
   Faster Resolution: Tasks are completed more quickly when handled by skilled individuals.
   Strategic Talent Utilization: Ensures that scarce expertise is used where it adds the most value.
   Supports Capability-Based Planning: Task allocation reflects organizational strengths and weaknesses.
4. Performance considerations:
   Expertise-based task assignment leads to higher quality outcomes, faster turnaround times, and lower rework costs—especially for complex or sensitive tasks. However, it can create bottlenecks if few individuals possess the required skills, and may reduce flexibility in task allocation. To avoid overburdening top experts, this approach should be supported by skill development programs and cross-training.

First-contact problem resolution

1. Definition: Establish a one-contact resolution for customer issues. Ensure that customers must contact the company only once to get their problems resolved.
2. Description: Companies should ensure that all information needed to solve customer issues are collected at the first encounter in the business process. This reduces the interaction effort on both sides and supports the fast and comprehensive identification of solutions.  Real-World Example; At Allianz, call center agents are instructed to serve customers in minimum time by prohibiting repeated calls, by permitting only one forwarding per call and by assigning the most appropriate agent available. This way, customers do not need to describe their problem or needs several times and get support as soon as possible.
   Implementation; This heuristic can be realized by reducing the number of loops in business processes and by proactively assigning the most suitable employee or IT-based touchpoint (e.g. chatbots).
3. Key Takeaways:
   Reduced Customer Effort: Minimizes frustration by avoiding repeated explanations and follow-ups.
   Streamlined Internal Processes: Fewer handovers and escalations simplify operations.
   Improved Customer Satisfaction: Quick, one-time resolution boosts perceived service quality.
   Requires Empowered and Skilled Frontline: Staff must be trained and authorized to resolve issues end-to-end.
   Supports Intelligent Process Design: Relies on smart routing, data collection, and integrated knowledge systems.
4. Performance considerations:
   This pattern leads to significantly improved customer satisfaction, lower handling times, and reduced operational costs by eliminating repeated interactions. It also enhances employee efficiency and system throughput. However, it requires well-trained frontline staff, well-integrated systems, and reliable initial data collection. The initial investment in training and systems may be high but is typically offset by long-term performance gains.

Green Compensation

1. Definition: Start implementing actions that can offset or counterbalance the environmental effects generated by business processes that cannot be changed.
2. Description: Some processes may be hard to redesign or restructure in regards to sustainability due to the nature of tasks they are performing or due to other internal restrictions. The challenge is to find a proper solution for compensating the environmental impact without changing the process. In order to provide a trustworthy compensation, organizations can implement a certified compensation alternative to improve visibility at the customer’s site. Solution: Whenever a business process that cannot be modified is initiated, a compensation process or activity is initiated, too. This process or activity compensates (parts of) the environmental impact caused by the original process.
   Results: Although the original process cannot be modified, the implementation of the pattern is able to achieve an improvement of the environmental impact from a global point of view because negative effects are not reduced, but compensated by positive effects. These positive effects may be further improved through an environmental certification of the corresponding compensation activities. 
   Examples: Production processes may require specific machines coming with a high upfront investment. These machines have certain well-defined process steps. The production waste originating from these machines, for example, may not be reduced without investing in new and expensive machines. So, although the production waste cannot be reduced, a donation for an environmental organization (e.g., for planting a tree or for buying rainforest) can be used to improve the environmental impact from a global perspective. Another example is the compensation of carbon emission occurred when burning fuel in auto mobiles. Oil companies provide a sustainability program that offers customers to compensate the amount of carbon dioxide for each refuel by investing in renewable energy. Variations: This pattern can be used in a custom way by using conditional compensations. For example, the compensation process or activity is only performed at every tenth initiation of the original process. This decision can be based on different aspects like waste that has been produced during process performance or the compensation value, for example.
3. Key Takeaways: 
   1. Unchangability Certain processes may be difficult to reconfigure for sustainability due to their nature or internal constraints.
   2. Compensate Initiate a compensatory process whenever an immutable business process begins, offsetting part or all the original process's environmental impact.
   3. Vary The pattern can be customized with conditional compensations, such as initiating the compensatory process only after a set number of iterations of the original process, based on factors like waste produced or compensation value.
4. Performance considerations: Although the original process cannot be modified, the implementation of the pattern is able to achieve an improvement of the environmental impact from a global point of view because negative effects are not reduced but compensated by positive effects. These positive effects may be further improved through an environmental certification of the corresponding compensation activities.

Green Variant

1. Definition: Offer a green alternative with the same outcome, utilizing different steps, resources, or partners, while retaining the previous existing process.
2. Description: Within business process optimization, organizations may face constraints that prevent them from switching entirely to greener processes-due to cost, policy limitations, or customer preferences. A full replacement could risk market share or operational feasibility. Instead, this pattern suggests offering an alternative process variant that reduces environmental impact while delivering the same functional outcome. The customer can choose between the conventional and the greener option. Challenges: Ensuring equivalent functional outcomes between variants. Solution: Develop a parallel green variant using different resources, technologies, or partners. Example: A trading company offers standard packaging (plastic/styrofoam) and an eco-friendly variant (biodegradable corn-based packaging), with a small customer-paid surcharge. Variations:
   1. Conditional variants based on customer or partner choice
   2. Green variants with slightly altered product or service features
   3. Context-based switching between green and conventional variants
3. Key Takeaways:
   Customer-Driven Sustainability: Enables eco-conscious customers to choose greener alternatives.
   Functional Parity: Green variants must offer the same core value or outcome as the original.
   Non-Disruptive Transition: Allows organizations to explore sustainability without abandoning existing processes.
   Flexible Execution Paths: Multiple variants can coexist and be selected based on context or preference.
   Supports Transparency: Customers are made aware of environmental trade-offs and choices.
4. Performance considerations:
   Offering a green variant helps reduce the ecological footprint without jeopardizing business continuity. It promotes sustainability through customer choice and enables incremental environmental improvements. However, managing multiple variants adds complexity to operations and may introduce trade-offs in cost, standardization, or throughput. Success depends on clear communication, seamless integration of variant selection, and alignment with customer values.

Isolate exceptions

1. Definition: Design business processes for typical cases and isolate exceptional cases from the normal flow.
2. Description: The pattern focuses on the recognition that exceptions in a workflow can disrupt normal operations and cause inefficiencies. To address this, the pattern suggests separating exceptions from the regular flow of work to improve overall process performance. By isolating exceptions, organizations can assign dedicated workers or teams who specialize in handling these unique cases. This enables the development of specialized expertise and knowledge, leading to more effective and efficient resolution of exceptions. Additionally, by filtering out exceptions, organizations can streamline their processes, potentially implementing Straight-Through-Processing where applicable, reducing manual intervention, and increasing operational efficiency.
   However, it's important to consider the trade-off between the benefits and the associated costs and complexities. Isolating exceptions can add complexity to the workflow, potentially decreasing its flexibility. It may require additional resources to train and develop specialized knowledge among workers. Without investing in specialized expertise, the desired improvements in handling exceptions may not be realized.Example; An illustrative example of this pattern can be found in a healthcare setting. In a hospital, the triage process serves as a practical application of isolating exceptions. Patients arriving at the emergency department are initially assessed by triage nurses who quickly identify urgent cases that require immediate attention, such as critical injuries or life-threatening conditions. These cases are isolated and given priority, ensuring they receive specialized care promptly. Meanwhile, the regular flow of patients is handled separately, improving the overall efficiency of patient care delivery in the hospital.
3. Key Takeaways:
   1. Specialized Exception Handling By assigning specific workers or teams to handle exceptions, expertise can be developed, leading to more effective resolution. 
   2. Straight-Through-Processing Filtering out exceptions may enable the implementation of streamlined, automated processes, reducing manual intervention. 
   3. Consider Complexity and Cost Isolating exceptions adds complexity to the workflow and requires investment in developing specialized knowledge.
4. Performance considerations: By separating exceptions, normal case handling becomes more efficient as workers can focus on regular cases without being disrupted by unfamiliar or complex situations. This reduces setup times wasted on dealing with exceptions that workers may not be adequately equipped to handle. The specialization of workers or teams in handling exceptions leads to the development of expertise, resulting in more effective and timely resolution of these unique cases. This can lead to improved customer satisfaction, streamlined processes, and reduced operational costs. Additionally, by filtering out exceptions and implementing Straight-Through-Processing, organizations can automate routine tasks, reducing manual effort and increasing process efficiency. However, it's crucial to carefully manage the added complexity that comes with isolating exceptions. The workflow may become more intricate, requiring proper coordination and communication between teams. Furthermore, organizations need to consider the investment required in developing specialized knowledge among workers handling exceptions, as it may involve training, resources, and ongoing support.

Offer Customer self-service

1. Definition: Offer customers the possibility to serve themselves.
2. Description: Companies should offer customers the possibility to perform tasks that were previously handled by employees. This includes activities like submitting applications, updating personal information, scheduling appointments, or tracking orders.
   When implementing this heuristic, companies should consider whether customers have the option to choose between self-service and traditional service channels. It's also important to recognize that not all tasks are suitable for self-service due to complexity, legal constraints, or the need for human judgment.
3. Key Takeaways: 
   Customer Empowerment: Enables users to take control of their interactions and solve issues independently.
   Resource Optimization: Reduces workload on employees, allowing staff to focus on complex or value-adding tasks.
   24/7 Availability: Self-service channels can operate outside traditional business hours.
   Not Universally Applicable: Some tasks still require human support or supervision.
   Design Matters: Success depends on intuitive interfaces and clear guidance for users.
4. Performance considerations:
   Self-service enhances empowered interaction capability by giving customers autonomy over task execution, and supports concerted interaction capability when integrated seamlessly with backend processes.
   It can reduce operational costs, speed up process execution, and improve customer satisfaction. However, the quality of self-service heavily depends on usability and system reliability. Poorly designed self-service options may lead to frustration, increased support requests, or data entry errors.

Offer temporal flexibility

1. Definition: Let customers interact with your organization whenever they want to.
2. Description: Companies should analyze when customers prefer to get in touch and adapt their business processes accordingly. From the customer’s point of view, temporal flexibility means being able to access services at any time—day or night.
   Real-world examples:
   1. REWE extended its opening hours into the late evening to accommodate customers shopping after work.
   2. National Bank provides 24/7 access to its credit card blocking service, ensuring immediate help in emergencies—even outside business hours.
      If human agents aren’t available around the clock, automated services like hotlines or chatbots can maintain availability.
3. Key Takeaways:
   Customer Convenience: Interactions can happen at times that fit customers’ personal schedules.
   Increased Responsiveness: Critical services (e.g. blocking cards) remain accessible when needed most.
   Competitive Differentiator: Around-the-clock availability can set a company apart in service quality.
   Supports Hybrid Delivery Models: Flexibility can be offered through both human agents and automated systems.
   Requires Process Adaptation: Back-office and support structures may need rethinking to support non-standard hours.
4. Performance considerations: Offering temporal flexibility strengthens:
   1. Individuated interaction capability: Customers act on their own terms.
   2. Empowered interaction capability: Customers initiate interactions without dependency on fixed business hours.
   3. Concerted interaction capability: Seamless handoffs between humans and machines support consistent service quality.
      This pattern improves customer satisfaction, retention, and engagement. However, it may require increased investment in staffing, automation, or system reliability to ensure consistent service during extended hours.

Parallelize activities

1. Definition: Consider whether activities may be executed in parallel. Instead of executing tasks sequentially, evaluate whether they can run simultaneously to reduce total throughput time and increase process efficiency.
2. Description: Consider whether activities may be executed in parallel.
3. Key Takeaways:
   Reduced Throughput Time: Tasks executed in parallel shorten the overall process duration.
   High Applicability: Many existing workflows contain unnecessarily sequential steps that can be parallelized.
   Increased Complexity: Requires careful coordination and control to avoid conflicts or errors.
   Cost Trade-Offs: Parallel execution may lead to performing unnecessary tasks in case of early knock-outs.
   Supports Scalability: Enables processes to handle higher volumes if infrastructure allows concurrent task execution.
4. Performance considerations: The obvious effect of applying this heuristic is that the throughput time may be considerably reduced. The applicability of the heuristic in workflow redesign is large. In practical experiences we have had with analyzing existing workflows, tasks were mostly ordered sequentially without the existence of hard logical restrictions prescribing such an order. A drawback of introducing more parallelism in a workflow that incorporates possibilities of knock-outs is that the cost of workflow execution may increase. The management of workflows with concurrent behavior can become more complex also, which may introduce errors (quality) or restrict run-time adaptations (flexibility).

Preference-based task assignment

1. Definition: Let people do what they love to do. Assign a task to a person based on the person’s preference. Preference is defined as a set of activities that the person is inclined towards and hence may have been executed more often along with higher execution efficiency by a person.
2. Description: This pattern builds on the idea that people perform better when they enjoy what they do. By aligning task assignments with personal preferences, organizations can increase motivation, engagement, and quality of work. Preferences may be explicit (e.g. stated in internal systems or surveys) or inferred from historical behavior, such as frequently executed tasks or higher efficiency in specific task types.
   Example: In a customer support team, agents who prefer handling technical queries are assigned to those topics, while others who prefer interpersonal interaction focus on billing or onboarding calls.
   Implementation: Requires mechanisms to capture and update preferences regularly and align them with operational needs without compromising fairness or workload balance.
3. Key Takeaways:
   Boosted Engagement: People are more motivated when working on tasks they prefer.
   Improved Performance: Preferred tasks are often performed faster and with fewer errors.
   Retention and Satisfaction: Employees are more likely to stay and grow in roles that reflect their interests.
   Requires Balance: Must be managed carefully to ensure fairness and avoid overburdening individuals with niche interests.
   Dynamic Matching: Preferences can evolve and should be regularly reviewed.
4. Performance considerations: 
   Assigning tasks based on personal preference can lead to improved speed, quality, and employee satisfaction. However, overfitting tasks to preferences may reduce flexibility and hinder team-wide skill development. There’s also a risk of uneven task distribution if only a few individuals prefer specific types of work. Combining preference-based assignment with broader rotation or development plans can help balance operational needs and individual motivation.

Process expansion

1. Definition: Extend existing processes by adding new steps, participants, or channels to increase value, reach, or functionality.
2. Description: Process expansion refers to the deliberate extension of a business process to cover new activities, touchpoints, or participants—either internally or externally. This can include adding new service steps (e.g., onboarding assistance), involving additional departments or partners, or expanding to new customer channels (e.g., mobile apps, self-service portals).
   The goal is often to enhance customer experience, enable upselling opportunities, or make processes more holistic. However, it requires careful orchestration to prevent added complexity or delays.
   Example: A traditional order process is expanded by adding post-sale engagement steps, such as delivery tracking, customer feedback collection, and loyalty enrollment.
3. Key Takeaways:
   Broadened Scope: Adds new value-creating steps or touchpoints to the process.
   Customer-Centric Enhancement: Improves experience by addressing additional needs along the journey.
   Enables Differentiation: Expanded processes can offer competitive advantages or new monetization opportunities.
   Increased Coordination Needs: Requires integration across teams, systems, or partners.
   Must Be Justified by Value: Additions should be purposeful and not overcomplicate the core process.
4. Performance Considerations: While process expansion can create additional value and differentiation, it may also increase execution time, resource usage, and coordination overhead. The added complexity can reduce flexibility if not modularized well. Therefore, expansion should focus on high-impact additions that clearly align with customer or business goals, and be supported by automation or integration where possible.

Reduce touchpoints

1. Definition: Reduce the number of contacts with customers and third parties.
2. Description: The exchange of information with a client or third party is always time-consuming. Especially when information exchanges take place by regular mail, substantial wait times may be involved. Each contact also introduces the possibility of intruding an error. Note that this heuristic is related to the Interfacing heuristic in the sense that they both try to improve on the collaboration with other parties.
3. Key Takeaways:
   Fewer Interruptions: Reduces the number of back-and-forth interactions.
   Shorter Throughput Time: Minimizes delays caused by waiting for external responses.
   Lower Error Risk: Fewer exchanges mean fewer opportunities for mistakes or data loss.
   Supports Process Simplification: Bundling information into fewer, richer interactions can streamline workflows.
   Trade-off with Completeness: Less contact can lead to less context or missing information.
4. Performance considerations: Reducing the number of contacts may therefore decrease throughput time and boost quality. Note that it is not always necessary to skip certain information exchanges, but that it is possible to combine them with limited extra cost. A disadvantage of a smaller number of contacts might be the loss of essential information, which is a quality issue. Combining contacts may result in the delivery or receipt of too much data, which involves cost.

Role-based task assignment

1. Definition: Assign tasks based on resources' roles in the organisation.
2. Description: 
   In role-based task assignment, tasks are allocated according to predefined organizational roles rather than individual characteristics. Roles typically represent a grouping of responsibilities, authority, and required competencies. By assigning tasks to roles instead of specific individuals, organizations can increase flexibility, simplify process models, and maintain clarity over responsibilities.
   Example: A "Quality Assurance Officer" role is assigned to review all product defect reports, regardless of which individual holds that role.
   This approach is particularly useful in scalable or dynamic environments where team compositions change frequently.
3. Key Takeaways:
   Clear Responsibility Mapping: Ensures accountability by linking tasks to formal roles.
   Flexibility in Execution: Any qualified individual within the role can take on the task.
   Standardized Assignment Logic: Simplifies process automation and workflow configuration.
   Supports Role-Based Access Control (RBAC): Aligns with IT system permissions and compliance models.
   Role Design Is Critical: Effective use depends on well-defined and maintained role structures.
4. Performance considerations: 
   Role-based assignment increases operational clarity and maintainability, especially in large organizations. It allows for seamless task reassignment and scaling without rewriting workflows. However, overly broad or vague role definitions can lead to mismatches, inefficiencies, or accountability gaps. Therefore, the success of this pattern depends on the precision and governance of the underlying role model.

Specialist-generalist

1. Definition: Consider deepening or broaden the skills of resources.
2. Description: Resources may be turned from specialists into generalists or the other way round. A specialist resource can be trained for other qualifications; a generalist may be assigned to the same type of work for a longer period, so that his other qualifications become obsolete. When the redesign of a new process is considered, application of the pattern comes down to considering the specialist-generalist ratio of new hires. 
   A specialist builds up routine more quickly and may have a more profound knowledge than a generalist. As a result, he or she works quicker and delivers higher quality. On the other hand, the availability of generalists adds more flexibility to the process and can lead to a better utilization of resources. Depending on the degree of specialism or generalism, type of resource may be more costly.
   Note that this heuristic differs from the Triage concept in the sense that the focus is not on the division of tasks.
3. Key Takeaways:
   Specialists drive depth: Higher quality and efficiency in narrow domains.
   Generalists drive flexibility: Useful in dynamic environments with shifting priorities.
   Impacts hiring strategy: Requires conscious design of team composition and job roles.
   Influences training investments: Cross-training or focused development changes depending on direction.
   Balance is context-dependent: Ideal ratio varies by industry, process type, and organizational strategy.
4. Performance considerations:
   Specialists can enhance speed and quality in task execution due to repetition and expertise, but limit the adaptability of the workforce. Generalists enable broader coverage and higher resource utilization, especially during workload fluctuations or absences. However, this may come at the cost of slower execution or more variability in output. Organizations must weigh quality, speed, cost, and flexibility when deciding how to structure their workforce skills.

Task delegation

1. Definition: Reassign tasks along the organisational hierarchy. Task delegation is when a person who was originally assigned a task passes it on to another person based on their position in the organisational hierarchy.
2. Description: Task delegation allows individuals—typically in higher hierarchical positions—to pass on tasks to subordinates. This mechanism helps balance workload, increase efficiency, and ensure that tasks are handled by those with the right level of responsibility or expertise. Delegation can occur proactively (built into the process) or reactively (based on availability or escalation).
   Example: A department head receives a customer complaint and delegates it to a team lead with relevant subject matter expertise.
   Delegation may also follow defined rules, such as delegation of authority (DoA) matrices or role-based access structures.
3. Key Takeaways:
   Workload Distribution: Ensures tasks are handled by available or better-suited personnel.
   Supports Scalability: Managers don’t need to handle every operational detail.
   Hierarchical Clarity: Aligns task handling with formal structures and responsibilities.
   Requires Clear Rules: Delegation must follow agreed rules to avoid confusion or risk.
   Enables Escalation Paths: Tasks can move both downward (delegation) and upward (escalation) as needed.
4. Performance considerations:
   Delegation can speed up execution by pushing decisions or actions to the most appropriate level, reducing bottlenecks at the top. It can also improve task ownership and team development. However, over-delegation without oversight may reduce accountability or lead to errors. Successful delegation requires clear criteria, proper training, and transparent communication.

Use eco-friendly resources

1. Definition: Replace underlying resources with eco-friendly alternatives.
2. Description: Organizations are using a multitude of resources for the operation of their business and the corresponding business processes. These resources need to be selected based on both the strategic business and ecological objectives the organization wants to achieve. Challenges; A resource is usually chosen by its functional capabilities. Selecting resources based on their environmental impact, however, can significantly influence the corresponding result. Additionally, proper metrics need to be defined and set-up in order to determine the different metric values of each resource. Solution; Exchange the underlying resources of certain activities Results;  Organizations will decrease their environmental impact by exchanging resources used by certain activities. The exchange of underlying resources usually does not affect the process structure. Thus, the process is performed as before, however, possibly with ecological-positive side-effects. Example; Resources are used or consumed in many cases. A company could, for example, decide to use green electricity instead of a conventional one. They may also decide to use different raw materials like non-plastic packaging for packaging their goods. Another example would be the use of cloud computing. This decreases the number of machines that an organization needs to hold available (e.g. for rare peak situations) and allows a demand-dependent use of these resources. Variations: Some resources display a different ecological impact based on other environmental factors, such as the form of available energy. A supplier of electric energy, for example, may provide greener electricity the windier it is at the location of his wind energy plant. This type of resource does not have to be exchanged but it is merely ensured that the same resource is used during certain time-slots in which its environmental impact is reduced.
   Relations to other Patterns;  Depending on the type of business process it may also be feasible to use Green Features. This pattern, however, may focus more on the appearance of a service or product rather than on an in-depth green process optimization.
3. Key Takeaways:
   Ecological Impact Reduction: Substituting conventional resources with eco-friendly alternatives directly reduces environmental footprint.
   No Structural Process Change Needed: Resources can often be swapped without changing workflows.
   Data-Driven Selection: Requires availability and comparison of environmental metrics across resource options.
   Context-Aware Optimization: Timing and conditions (e.g. energy source availability) can influence how green a resource is.
   Scalability: The pattern can be implemented gradually across different process segments.
4. Performance considerations:
   Using eco-friendly resources can support sustainability goals without major disruptions to operations. In many cases, operational costs may increase initially (e.g. green energy premiums), but long-term reputational and regulatory benefits can offset them. Additionally, organizations may see cost reductions in areas like energy efficiency or resource optimization. Flexibility and resilience can also improve through demand-based and context-sensitive resource use (e.g. cloud scalability or dynamic energy sourcing).

Workload-based task assignment  

1. Definition: Allocate tasks based on individuals' incomplete workload. Assign tasks to people based on their workload, which refers to the number of task instances started but not yet completed by a person.
2. Description: In traditional workflows, tasks are often distributed uniformly or based on availability windows without considering the actual workload already assigned to each individual. This pattern addresses that gap by dynamically assessing how many tasks are already in progress per resource and steering new assignments accordingly.
   Example: In a customer service center, incoming support tickets are routed to agents with the fewest active tickets currently open. This ensures that no single agent is overwhelmed while others are underutilized.
   Implementation: Requires tracking of task states per resource (e.g., task started, not yet finished). Integration with task management or BPM systems is necessary to access this information in real time.
3. Key Takeaways:
   Fairer Task Distribution: Balances workload across team members to prevent burnout.
   Improved Throughput: Avoids bottlenecks caused by overburdened individuals.
   Real-time Monitoring Needed: Accurate allocation depends on current task status visibility.
   Scalable in Dynamic Environments: Especially useful in fast-paced settings with high task volume variability.
   Complementary to Other Assignment Strategies: Can be combined with performance-, expertise-, or role-based strategies.
4. Performance considerations:
   This pattern enhances throughput time by reducing queues in front of overloaded resources. However, it may neglect factors like skill level or task complexity, leading to quality variations if applied alone. In highly specialized environments, combining workload-based assignment with other heuristics (e.g., expertise-based or quality-based assignment) is recommended to avoid mismatches. Additionally, it can increase the need for more frequent monitoring or automation, which may add coordination overhead.
