A Framework for Applying Lean
Many structured approaches exist for improving processes and solving problems. The Plan, Do, Check, and Act (PDCA) approach has existed for a long time. Define, Measure, Analyze, Improve, and Control (DMAIC) is used with the Six Sigma methodology. Lean uses a similar approach, although no acronym is usually associated with it. The steps are as follows:
- Map the process, thereby creating the current state value stream map.
- Analyze the current state value stream map looking for unnecessary lead time and possible ways to reduce that wasted lead time using Lean tools.
- Draw the value stream map that reflects ideas for improving the process and reducing its lead time: This is called the future state value stream ...
