This document discusses measuring IT service management (ITSM) processes using key performance indicators (KPIs). It recommends choosing KPIs that are balanced across four categories: compliance, quality, performance, and value. Examples of KPIs are provided for each category. A KPI sheet is suggested to document each KPI's name, owner, calculation method, and other details. Process scores can be calculated by averaging KPI scores. The overall ITSM health can be viewed either as an average of all process scores, or by averaging KPIs into the four categories.
