In recent discussions, we have kept Lean in its simplest form the last week with breaking it down to the 4 Cycles, CAP-Do, EDCA, PDCA, EDCA . We provided scope and assembled a team using the SALES acronym: https://business901.com/blog1/lets-make-lean-simple-again/. We used the Leval of Perspectives to understand the highest leverage of action we can take: https://business901.com/blog1/positioning-lean-for-success/.
However, none of it works at all if we do not put the proper coaching in place. I use the basics of the Toyota Kata both at a macro and micro level. The coaching questions may change some but the principles do not. If you are not familiar with Toyota Kata this is the Amazon link: http://amzn.to/2xJsAh8.
