Leading Lean: Missed Opportunity [the broken link was removed] by Jamie Flinchbaugh:
Great points. One of the counter intuitive things with lean is to make problems visible. So often people try to hide problems (which inventory can do – making it difficult to see emerging problems and to diagnose problems once they are finally discovered).
The idea that you then must improve the system as these problems are made visible is fairly obvious but is also worth emphasising since without it the problems increase.
I think the typical perfromance appraisal process adds to the desire to hide problems. As does excess mobility of management (just hide it until you move on). These show my Deming view of management leanings.
