This document discusses Key Performance Indicators (KPIs) and how they are used to measure business objectives. KPIs can be measured at multiple levels of an organization, from overall enterprise performance to processes within departments. Good KPIs are connected to corporate goals, are decided by management, and are specific, measurable, achievable, relevant, and time-bound. The document provides examples of KPIs related to employees, managers, and departments that measure factors like turnover rate, customer lifetime value, and equipment availability.
