Objective: Release and Deployment Management aims to plan, schedule and control the movement of releases to test and live environments. The primary goal of this ITIL process is to ensure that the integrity of the live environment is protected and that the correct components are released.
The activities and process objectives of the Release and Deployment Management process in ITIL V3 are mostly identical to Release Management in ITIL V2. ITIL V3 Release Management provides considerably more details in the areas of Release planning and testing; this led to the addition of two dedicated processes which were subsumed under Release Management in the previous ITIL version: Project Management - Transition Planning and Support, and Service Validation and Testing.
In ITIL 2011 Release Management is called upon from Project Management to perform the detailed planning of Release build, Release test and Release deployment.
Additional interfaces between Release Management and ITIL Project Management have been introduced to ensure that Project Management is kept up-to-date with current planning information.
The process overview of Release & Deployment Management (.JPG) shows the key information flows (see fig. 1).
The ITIL 2011 guidance also specifies that Minor Changes are implemented by Change Management without the involvement of Release Management, so the Minor Release Deployment sub-process has been removed.
The latest edition of ITIL 4 describes the key activities of Release and Deployment Management in the service management practice of "Release Management" and the technical management practice of "Deployment Management".
These are the ITIL Release Management sub-processes and their process objectives:
Release Management Support
Release Planning
Release Build
Release Deployment
Early Life Support
Release Closure
The following ITIL terms and acronyms (information objects) are used in the ITIL Release Management process to represent process outputs and inputs:
Development Work Order
Installation Work Order
Release Policy
Release Record
Release Unit
Release Manager - Process Owner
