You can use change request work items to track and control all changes to the product and supporting systems. All change requests are started as the result of a deviation from the baseline, which consists of the original requirements that were identified for the project. For example, if a meeting with a user uncovers new requirements, a change request should be created to propose updating the requirements baseline. For more information about CMMI, see Background to CMMI.

Create a change request

When you realize that an original requirement must change, you create a change request work item and link it to the old requirement work item by using an Affects link type. A requirement work item that has details of what is new or has changed should also be created and linked to the change request. All change requests are extensively analyzed for impact on the user, product, and teams. During this analysis, tasks may be broken out for estimation. These new task work items should be linked to the new requirement work item to provide traceability. This result is accomplished by adding the tasks on the Implementation tab of the work item form.

The change request and resultant new work items must contain details of all new work that is required and all existing work that is to be removed, modified, or obviated. You can create a change request from the home page of the web portal or from the Work page in Team Explorer as described in Get started using work items. You can specify the change that you're requesting in the Title field, the team member who owns the change, and other information about the request.

For more information about how to complete the work item, see CMMI work items and workflow.

Analyze a change request

Before a change request is analyzed, it should be triaged by a configuration control board. A configuration control board is a group of people who are responsible for approving and denying change requests and who ensure that changes are implemented correctly. You can indicate that a request must be triaged by setting the Triage field in the work item to Pending. For more information, see Change request fields (CMMI). Analysis of change requests can be a drain on resources, and it's important that the change request queue doesn't put undue demands on the team and affect the project timeline.

A change request should be analyzed to determine the scope of its impact on existing and planned work. The effect must be known so that it can be used to estimate the cost in person-hours to implement the change.

Analyze the risk of accepting the change. Are external teams dependent upon the code or feature that would be changed, and could their schedules be adversely affected? Could assignment of resources to this change adversely affect other important feature areas or requirements of the product?

As part of your analysis, request input from stakeholders and add input to the change request work item. If the change requires changes to other planning documents, add the changes to the change request. Then, change those documents as appropriate. These changes will maintain the revision history and enable everyone to see the details. The revision history mitigates risk from bad communication and provides important evidence for a Standard CMMI Appraisal Method for Process Improvement (SCAMPI) appraisal.

If a change request is accepted, change the State from Proposed (the default for new change requests) to Active.

Monitor change requests

While a change request is active, you can monitor it by viewing the Open Change Requests With Requirements query. Also, you can create an email alert for when a Change Request is created. Change requests should be processed in a reasonable amount of time.

If a change request doesn't receive the attention that it requires, escalate the matter by creating an issue work item. Link the new issue to the change request, and escalate the issue to get the change request impact assessment on track.
