Principlev1
After successfully improving a constraint, immediately
After successfully improving a constraint, immediately re-identify the system's new bottleneck, because constraint improvement shifts the limiting factor to a different component.
Why This Is a Principle
Derives from The behavior of a system arises from its structure, not from (system structure determines behavior) and Single-loop learning adjusts actions within existing (single-loop vs double-loop learning). This prescribes ongoing re-assessment rather than one-time optimization. It's the iterative discipline that makes bottleneck-first work.
