I just invented this one…
All those consultants that try to force Lean down the throat of the managers that, according to them, are too dumb to “get it” are just, IMHO, plain wrong. This is the surest path to “change resistance“. Of course, telling is quicker than letting people experiment and trying to understand things from the perspective of the people.
Yet, if management is supposed to learn how to have their people conduct experiments, and then learn from them, then share them with their colleagues throughout the organization, why on earth are they lecturing and teaching them Lean?! If managers learn anything, that will be to continue in command-and-control mode and impose Lean tools and processes onto employees that won’t necessarily understand the purpose of them. And since the managers don’t know exactly how things happens on the Gemba (of many managers do “standing in the circle” for hours ?), they commands will be just resented as unsuited at best by employees, further decreasing their engagement levels, and the few trust left they might have had in their managers.
Is that really what’s wanted?
Of course, putting on my “Systems Dynamics” hat, I can see that the more consultants do it that way, the less organizations really improve on the long-term, and the more need will be felt for more Lean consulting.
I am not saying that consultants want the situation to be that way. I’m just saying that doing more of the same Lean teaching method will just produce more of the same long-term failed results.
