GEMBA
- Structured Approach
- Can Collect Qualitative and Quantitative
- Systematic Walk (By knowing our Purpose, Place, Framework and Validate it)
- Focus on Process not on People
MBWA
- Unstructured Approach
- Can Collect Qualitative Information
- Random Walk (Just like Wandering in Workplace and Talking to people)
- Focus on People
There is no much functional difference on both things but the outcome of Gemba Walk can be differ from MBWA outcomes as Gemba Walk is structured approach.
So can say MBWA is subset of Gemba Walk.
