ADP (Administration, Detection, Prevention)

Framework for evaluating countermeasure strength from weakest to strongest. Administration (weakest): relies on procedures, training, checklists, and inspections—depends on people following rules consistently. Detection (medium): uses Jidoka, error-proofing (poka-yoke), or in-process checks to catch defects before they escape—catches problems but doesn't eliminate root cause. Prevention (strongest): eliminates the conditions that allow problems to occur, similar to Mizen Boshi philosophy—makes defects impossible rather than detectable. Coaching tool to push teams beyond administrative controls toward true prevention. Example: instead of 'train operators better' (A), aim for 'redesign fixture so part can only be installed correctly' (P).
