The video mentioned a sensei.  At Belt Course, we prefer Coaches.  Do you have active access to a coach in your organization that has already traveled the path that you want to take?   Can this coaching program supplement that coaching?

Have you struggled before with starting a Lean implementation in just one product family?  (Possible reasons: too many product families, too many shared assets) Have you considered starting with one whole site (plant) instead and focus on the plant bottleneck/constraint?

To identify an early win, have we identified a plant or division where we have the readiness to implement an Operating System?  Could we use this as an example of what's possible to show other plants/divisions?    During a "Beginning" Coaching call, we'll be able to help you with this step.
