KPI stands for Key Performance Indicators.
KPIs measure specific human resource activities that contribute to the efficiency and effectiveness of a company. KPIs provide a company with quantitative measurements that can be used to examine qualities and actions that contribute to long-term success. KPIs are evaluated by leading and lagging indicators.
Leading indicators anticipate, precede, and predict future performance. For example, time to fill a vacancy.
Lagging indicators measure the result of a process or change and often gain more consideration because they analyze revenues that executives use to measure success.
