The practical question
Measure capacity, access, fidelity, and sustained change.
Use this page as a controlled working guide. Adapt language and activities to the population, verify local resources, assign ownership, and preserve the clinical and life-safety boundaries described throughout the model.

Measurement 03
SEC-36Fidelity without rigidity; adaptation without drift
Fidelity protects the mechanisms that make the model useful. Adaptation allows the program to fit age, culture, language, setting, and lived reality. Drift occurs when the program changes accidentally, silently, or for convenience without reviewing the impact.
Core components that should remain stable
Plan–Do–Study–Act
PlanDefine the problem, theory, change, target, owner, measure, and prediction.
DoTest at a controlled scale and document what actually occurred.
StudyCompare result with prediction; examine variation, voice, equity, and unintended effect.
ActAdopt, adapt, abandon, or test again—then record the decision.
