Performance management is the broader discipline that includes setting direction (objectives), selecting measures (KPIs), tracking results (performance measurement), reviewing progress, diagnosing issues, and executing improvement initiatives. Therefore, performance measurement is a subset of performance management . Performance management cannot be done well without measurement (so A is incorrect), and the terms are not synonyms (so C is incorrect). While specialized staff can support measurement design and governance, measurement should not be isolated to specialists only; operational teams must understand and own the metrics, otherwise results won’t drive action (so B is not the best statement). This distinction matters in KPI programs: organizations often build dashboards but fail to create the management routines that turn data into decisions—leading to “measurement without management.” A solid KPI implementation plan includes not only metric definitions and data pipelines, but also review cadences, accountability (KPI owners), action tracking, and escalation. Keeping measurement inside the larger management system ensures KPIs are used to improve performance rather than merely report it.
