Build measurement systems before executing strategies, not

Why This Is a Principle

Derives from Hindsight Bias and Calibration Necessity (memory reconstruction unreliability), The behavior of a system arises from its structure, not from (system behavior emerges from structure), and Self-monitoring of behavior produces significant and (self-monitoring affects goal attainment). The lesson emphasizes 'build the dashboard before you need it'—the principle prescribes proactive instrumentation because retrospective measurement is contaminated by biased reconstruction.
