Key Failure Indicator (KFI)

A key failure indicator is a chosen measure intended to warn of a specific undesirable outcome or emerging process problem. Its predictive value and lead time need checking. It overlaps with key risk indicators and may complement performance measures, which can themselves include negative outcomes.

A warning indicator needs a plausible link to a failure you want to prevent. Define the undesirable outcome first, then identify a condition that may precede it with enough time to respond. A rising number is not an early warning merely because it sounds negative; complaints, for example, may rise after harm or because reporting became easier.

Connect the signal to a proportionate action and evaluate false alarms as well as missed warnings. A useful threshold should prompt investigation, not automatic blame. Record whether the indicator provided relevant lead time and whether the response helped, then change or retire signals that create noise without improving decisions.
