2. Measure:
- Purpose: Establish a baseline performance metric by collecting relevant data on the current process.
- Steps: Define key performance indicators (KPIs), collect and analyze data, and create process maps to visualize the current state.
3. Analyze:
- Goal: Identify root causes of defects or variations using statistical analysis and problem-solving techniques.
- Techniques: Fishbone diagrams, hypothesis testing, and regression analysis are commonly used tools in this phase.
4. Improve:
- Focus: Develop and implement solutions to address identified issues, focusing on sustainable process improvements.
- Strategies: Design of Experiments (DoE), value stream mapping, and process reengineering are employed to optimize processes.
5. Control:
- Objective: Establish control mechanisms to ensure sustained improvement and prevent regressions.
- Activities: Create standard operating procedures, monitor process performance, and implement feedback loops.
