Architecture Change Request is one of the TOGAF deliverables you can create with the TOGAF software.

This document is an Architecture Change Request for the ${PROJECT, PROP=name} project.

The goal of an architecture change management process is to ensure that the architecture achieves its original target business value. This includes managing changes to the architecture in a cohesive and architected way. The change management process will determine:

  • The circumstances under which the enterprise architecture, or parts of it, will be permitted to change after deployment, and the process by which that will happen
  • The circumstances under which the architecture development cycle will be initiated again to develop a new architecture

The Architecture Board assesses and approves Architecture Change Requests.

Step 1: Develop Change Request

Fill-in the Architecture Change Request form

During implementation of an architecture, as more facts become known, it is possible that the original Architecture Definition and requirements are not suitable or are not sufficient to complete the implementation of a solution. In these circumstances, it is necessary for implementation projects to either deviate from the suggested architectural approach or to request scope extensions. Additionally, external factors – such as market factors, changes in business strategy, and new technology opportunities – may open up opportunities to extend and refine the architecture.

In these circumstances, a Change Request may be submitted in order to kick-start a further cycle of architecture work.

You can create and document a change request by filling in the form provided under this activity.
