Change, Project, and Release: the core of IT Service Supply Chain (Part 2)
By Laurent Duenas, March 15th 2013
Main objectives of Release and Deployment Management
Contribute to the agility of the organization
Release and Deployment Management process activities include the chronological sequence of operations to carry out before new IT Services (or their evolutions) are implemented into the Live environment. Their arrangement and the efficiency of applied methods contribute to meet business deadlines too (i.e. time-to-market).
By optimizing its activities and their industrialization, the Release and Deployment Management process aims at building efficient “supply chains”*, which guarantee the organization's agility.
* We refer to several supply chains because depending on the type of component, their release is not identical and needs specific implementation and control operations.
Contribute to risk reduction on change
The activities of this process also include operational risk assessment and can implicitly impact on IT Service release.
Just like for Change Management, Release and Deployment Management includes check-up and “Go / No Go” activities, as well as release implementation methods* themselves (integrated into models), aimed at reducing these risks in the release environment.
* We mention here test and deployment methods aimed at improving change release reliability.
Reduce cost of Change release
Just like for any sequence of operations to be repeated, capitalization of good practices and experience gained lead to standardized methods, optimized resources, automated acts, all of them reducing the implementation cost of release activity.
That is why Release and Deployment Management is a key contributor to the control and where applicable the reduction to the cost of change release.
Control deployed release components
.This point targets an objective specific to Release and Deployment Management (which you do not find in Change Management).
Combined with Service Asset and Configuration Management (SACM), Release and Deployment Management is a control and “locking” tool of all components deployed in the Live environment. The first one identifies inconsistencies, the second one makes sure that deployed components are authorized and deployed from the Definitive Media Library (DML).
