Which of the following words is not a KPI lifecycle phase?

A KPI lifecycle typically includes phases such as selection (choosing the right measures aligned to objectives), documentation (defining formula, data source, owner, frequency, target, tolerance), activation (making the KPI operational—instrumentation, data pipelines, roles, reporting cadence), and then ongoing reporting, review, and refinement . “Notification” is not usually recognized as a standard lifecycle phase; notifications can be a feature of reporting tools (alerts, reminders) but they are not a core lifecycle stage. Treating notifications as the “work” can be a pitfall: KPI success depends more on proper definition, reliable data gathering, governance, and consistent review routines than on automated alerts. In practice, activation often includes assigning a KPI owner and data custodian, confirming the data source, building the collection process, and running a pilot to validate accuracy. A common measurement challenge is poor adoption after selection—teams select KPIs but never operationalize them. Clear lifecycle steps prevent that gap and ensure the KPI becomes a trusted management instrument rather than a one-time exercise.
