- Numerator
- Counted outcome from the aligned source
- Denominator
- Eligible comparison population
- Reproduce
- Calculate without premature rounding
- Validate
- Reconcile detail, summary, and reported KPI
Plausibility cannot replace verification. Preserve the numerator, denominator, unit, scope, period, formula, precision, and reconciliation record.
