What Is An ISO/IEC 20000-1 Release Post-Implementation Review Template? An ISO/IEC 20000-1 Release Post-Implementation Review Template is a structured document used to evaluate the effectiveness and outcomes of an IT service release after implementation. It helps service management teams review whether the release achieved its intended objectives, identify incidents, service impacts, issues, risks, deviations, lessons learned, and improvement opportunities, and document actions required after implementation. For organizations operating an ISO/IEC 20000-1 Service Management System (SMS), a post-implementation review provides a practical way to evaluate changes and releases and use the results to improve service management activities.
