Learning to See: Value Stream Mapping to Add Value and Eliminate MUDA
This is the standard workbook on value stream mapping, one of the core tools of Lean. Rother and Shook walk through the method step by step: map the current state, design the future state, and find the waste (muda) hiding between them.
It reads more like a field manual than a business book, with worked examples you can follow with a pencil. That is its strength.
Useful for anyone doing process improvement, from managers to the people who actually run the process.
