Thanks to Mark Graban for his post “Management By Walking Around” vs. “Gemba Walks"
I agree, leaders must go and see what is really happening.
Without knowing what you are watching for, "stand in the process and think for yourself," The Toyota Way, on Ohno circle.
For those who feel uncomfortable with the emphasis on Lean or TPS, Graban shared this quote from Deming.
"Management by walking around’ is hardly ever effective. The reason is that someone in management, walking around, has little idea about what questions to ask, and usually does not pause long enough at any spot to get the right answer.”–W. Edwards Deming, Out of the Crisis
