Anyway.  One thing that people try in an attempt to stave off a Lean conversion is to "teach" you "how it is really done."  I can't count the number of times that I've sat, mouth hanging open, as someone "explains" to me how things should really work.  As though anyone who has worked in this industry hasn't heard it all before.  Specifics aside, it always amounts to one of a few arguments.

"Just batch up a bunch of work and costs will go down."

"Just skimp on quality and costs will go down."

"Just create large queues and costs will go down."

Pish posh.

These arguments always remind me of an old generation of scientists who simply refuse to accept a newer, better theory in spite of all the evidence such as was the case with the transition from phlogiston theory to the oxidation theory of combustion.

What is being taught in these scenarios is always the most advanced interpretation of the old theories available - the "state of the arcane," if you will.

What I need is a way to validate that someone has a highly advanced understanding of an out-of-date thought-framework so that I can validate what they do know without accepting what they believe as the truth.

Any ideas?
