We’re Not Militant
There are a handful of very well known Lean consulting firms that you can pay up to $60K/week to come into your business to bark at you and make you feel bad about your current processes. They bring a “proven”, canned, one-size-fits-all Lean deployment system and expect you to refer to them as “sensei”.
They are definitely experts in Lean (and they are not shy about telling you so), but they don’t seem to want to be experts in your processes.
Most of the stories I hear about these “Lean boot camp” companies end with relief once they were gone, frustrated employees who want no more part of Lean, and weeks of “putting things back to normal”.
