KBM 15 Modeling Business Processes with EPK

In this module, you will learn the systematic representation and analysis of business processes using event-driven process chains (EPK). You will be able to identify, model, and evaluate core and support processes. The focus is on the practical application of the EPK method for visualizing workflows, analyzing interfaces, and continuously improving business processes in an operational context.

Concepts and Background

Event-driven process chains (EPK)

A graphical modeling tool for representing business processes that uses events, functions, branches, and connections as elements to map the logical flow of business processes.

Core processes

The primary, value-adding activities of a company that directly contribute to the creation of products or services and directly influence customer benefit.

Support processes

Helper functions that enable core processes but do not provide direct customer benefit, such as human resources, IT support, or administration.

Continuous improvement process (CIP)

A systematic approach to the constant optimization of business processes through regular analysis, measurement, and adjustment to increase efficiency.

Interface analysis

The examination of connection points between different processes, departments, or systems to optimize information and material flows and minimize friction losses.

Practical Steps

1. Define process objectives: Clarify the purpose and expected outcomes of the process to be modeled. This creates the basis for later evaluation.
2. Set process boundaries: Determine the start and end points of the process, as well as the involved departments and actors. This creates a clear framework for modeling.
3. Identify events: Collect all triggers for process activities that are not conditioned by previous process steps. Start with the first event of the process.
4. Assign functions: Assign the corresponding function to each identified event that is executed in response to the event. Use active verbs for naming.
5. Create connections: Connect the functions and events with arrows to represent the process flow. Pay attention to the order and dependencies.
6. Insert branches: At decision or condition points (XOR, OR, AND), insert the corresponding symbols to represent alternative process paths.
7. Mark interfaces: Mark all interaction points with other processes or systems with special symbols or colors for later analysis.
8. Validate the model: Check the created EPK model for completeness, consistency, and plausibility with process participants.
9. Evaluate the process: Analyze the modeled process for efficiency, effectiveness, and improvement potential based on defined metrics.
10. Implement optimization: Derive concrete measures for process improvement based on the evaluation and implement them step by step.

Knowledge Check

Four questions for self-assessment. Click on each question to see the correct answer and explanation.

What is the main purpose of event-driven process chains (EPK) in business process modeling?

• A) The pure documentation of organizational structures
• B) The graphical representation and analysis of business processes
• C) The calculation of cost centers
• D) The creation of personnel plans

Correct answer: B. EPK serves the graphical representation and analysis of business processes, not pure documentation or other administrative tasks.

Which type of process directly contributes to the creation of products or services and immediately influences customer benefit?

• A) Support process
• B) Management process
• C) Core process
• D) Leadership process

Correct answer: C. Core processes are primary, value-adding activities that directly contribute to the creation of products or services, while support processes only represent helper functions.

Which element of the EPK triggers a process function and marks the beginning or continuation of a flow?

• A) Connection rule
• B) Function
• C) Event
• D) Branch

Correct answer: C. Events trigger functions and mark the beginning or continuation of a flow, while functions represent the activities to be performed.

What is the primary goal of continuous improvement of business processes?

• A) The increase in personnel numbers
• B) The reduction of process steps
• C) The constant optimization of processes for efficiency and effectiveness
• D) The documentation of historical workflows

Correct answer: C. The primary goal of continuous improvement is the constant optimization of processes for efficiency and effectiveness through systematic analysis and adjustment.
