Implement each optimization change on a small, contained scale before system-wide deployment, because localized testing isolates effects and limits damage from failed experiments.
Why This Is a Principle
Grounded in Learning occurs when outcomes differ from predictions… (learning from error), Externalization Exposes Hidden Structure (externalization reveals gaps), and Complex systems that work evolved from simple systems… (complex systems evolve from simple ones). This is the 'Do' step of PDSA as a principle: test before you scale.
