Episode notes
One-Piece Flow Changed Careers
- Royden used Ron's one-piece-flow video to shock his shop floor into rethinking batch production.
- Operators recorded calculations and many later embraced lean because the demo made the idea obvious.
Operating Systems Need Rhythm
- Operating systems need a rhythm to work; talking is uneven, singing is rhythmic and predictable.
- Leaders must match their style to the organization's phase so the system achieves flow.
Stabilize Before You Standardize
- Stabilize before you standardize or improve by focusing on repeatability and predictability.
- Go slow to go fast and invest in people capability while relying temporarily on skilled operators.
