An IT Service Provider must follow the different phases of the release management procedure. This process and its five phases are discussed in detail in ITIL courses. They can also be asked about in the ITIL exam. This is an important step in the ITIL Service Transition phase of the ITIL Lifecycle. The change management process is closely linked to the release management process. This is the stepping stone between the Service Transition Stage and the ITIL Service Operation Stage, where live services can be accessed by the customer or end-user. Let’s take a look at each stage and how they relate to the deployment or upgrading of services.
The 6 stages of the release management procedure
This figure shows the high-level overview for each phase. The entire process is connected to the change management process, as you can see. There are four authorization steps that feed into change management, and one release management process that feeds into it.
Release management: Planning for release and deployment
As you can see, the first step in the planning of release management and deployment management is important. This planning must be authorized by the IT service provider’s change management. The planning stage of the release management process plays an important role in any process. Planning is key to the efficiency of all phases of the release management process. Release management and deployment planning make sure that there are plans in place for possible mishaps so that the release process and deployment can run smoothly.
Building and testing the release management process
Service packages are built, tested, and released based on the deployment and release planning. Customers and businesses will have new requirements. Production will also encounter problems. To meet customer and business requirements, as well as fix production problems, new services and/or modifications to existing services will be required. Every change in service must be approved. After the service package has been built and released, it must then be tested to avoid any problems in production. This is the final phase of the release management procedure. The person responsible for change management can then sign off the final service.
Release management process: definitive library
Next, updates are added to the definitive media library. The definitive media library is a virtual space that stores all services and configuration items. Only tested and proven configuration items and services are allowed to be part of the definitive library. IT developers can only use items from the definitive library to create new services. This is why the release management steps are so important. It is possible to include a thoroughly tested new service into the definitive media library without hesitation.
New services packages are being deployed
Now it is time to release, build and test service packages for customers. After each service is retired, new service packages will be deployed. The new version of each service package will be added to the definitive media library after every change. The service’s constant evolution is what keeps it alive and adds value to the customer and business.
Close the review
The final phase of each deployment is reviewed and closed. This phase is where the post-implementation review takes place to evaluate the deployment and integration of the new service package into the production environment. The new service packages should be closely monitored
