Open Group IT4IT Reference Architecture Release Composition Component

​Purpose

• Manage the Release Package, Service Release, Service Release Blueprints, and overall Service Release for developing and delivering new or changed services to the R2F Value Stream Fulfillment Execution functional component to facilitate a smooth transition to IT operations.
• Create the Service Release, Service Release Blueprint, and Release Packages that will be utilized by the Test functional component and later the Fulfillment Execution functional component (R2F Value Stream) to create a specific deployment for a specific IT service instance (including service system and/or service offer).
• Begin the creation of monitors, batch processing, backup/restore, etc. for the service, to ensure supportability as part of IT operations enablement.
• Manage the release artifacts within the Release Package by centralizing all elements of the Service Release Blueprint from the various functional components:
• Requirement functional component: requirements per Release Package
• Source functional component, as well as maintenance scripts: documentation
• Build Package functional component: Build Package
• Test functional component: test results as well as automated tests for validation post deployment
• Defect functional component: Known Errors (issues/defects)
  

Main Functions

The Release Composition functional component:

• Shall be the system of record (authoritative source) for all Service Releases.
• Shall associate a Service Release to a service.
• Shall allow a recursive relationship between Service Releases.
• Shall associate a Service Release to one or more Service Release Blueprints.
• Shall be the system of record for all Service Release Blueprints.
• Shall associate a Service Release Blueprint to a service.
• Shall associate a Service Release Blueprint to a Release Package.
  

If a Project functional component exists, the Release Composition functional component:

• Shall associate one IT Initiative to one or more Service Releases which are defined to deliver this IT Initiative.

If a Service Design functional component exists, the Release Composition functional component:

• Shall associate one Logical Service Blueprint to one or more Service Releases which are designed to deliver this Logical Service.

If a Requirement functional component exists, the Release Composition functional component:

• Shall associate one Service Release with one or more Requirements which are fulfilled in this release.

If a Test functional component exists, the Release Composition functional component:

• Shall associate one Service Release with one or more Test Cases.
• Can receive test-related information that should be included in the Release Package from Test Management.
  

If a Build Package functional component exists, the Release Composition functional component:

• Shall associate one or more Service Release Blueprints to one or more Build Packages.
• Can receive one or more Build Packages that should be included in the Service Release Blueprint.
  

If a Service Level functional component exists, the Release Composition functional component:

• Can provide service contract information for creating a Service Contract.
• Shall associate one or more Service Release Blueprints to one or more Service Contracts.
  

If a Fulfillment Execution functional component exists, the Release Composition functional component:

• Can provide information required for service instantiation to the Fulfillment Execution functional component.
• Shall associate a Service Release Blueprint to one or more Desired Service Models.
• Shall associate a Service Release Blueprint to one or more Fulfillment Requests.
  

If a Catalog Composition functional component exists, the Release Composition functional component:

• Can provide information required for creating a Service Catalog Entry to the Catalog Composition functional component.
• Shall associate a Service Release Blueprint to one or more Service Catalog Entry(ies).
  

If a Defect functional component exists, the Release Composition functional component:

• Shall associate one or more Service Release Blueprints to one or more Defects.
• Can receive Defect-related information that should be included in the Release Package.
