Lean Panacea?

Do you believe Lean is a panacea?

I was in a presentation this week and it was clear that people in the audience felt that 'Lean' was the answer to all their problems. They had all tried things before but this time 'Lean' was going to make the difference.

So what is Lean - is it some form of magical power that transforms unsuccessful organisations into successful ones or a genie in a bottle which (when released) can make improvement programmes go further and faster than ever before?

Of course it isn't.

Lean has the power to do good if done well and the power to do great harm if not.

For many people who think their previous improvement attempts have not worked is because they either have been sold a Turkey (by a consultant who has read a book on XYZ Methodology) or they have not prepared their organisation effectively for the change or supported it after the change.

Will 'Lean' stop these problems? Is it possible that many of the people who claim to be 'Lean Experts' have just read a book or that many of the organisations engaged in Lean will not prepare their organisation and/or support it?

What do you think?
