Principlev1
Combine multiple imperfect upstream metrics into composite
Combine multiple imperfect upstream metrics into composite leading indicators rather than relying on single predictors, because composite signals smooth individual noise while preserving shared directional information.
Why This Is a Principle
Derives from Every detection system faces a fundamental tradeoff between (signal detection tradeoff) and Process variation consists of two fundamentally different (common cause vs special cause variation). This is the Conference Board's composite indicator principle generalized — about how to aggregate weak signals into strong ones.
