I define a change request as a clear, well‑argued request to change one or more baselined requirements. First, I record the request with all relevant attributes. Second, I use a consistent template. For example, I include project name, request number, title, date, and requester. In addition, I add origin, functional responsibility, and change type. Moreover, I list status, requester priority, and implementation priority. Also, I name the tester, update date, version, and release. Furthermore, I add forecast effort for specification and implementation. Finally, I give a clear description of the change and space for comments.
I specify types of change requests. For example, I mark a spec error as a corrective change. I label scope change as an adaptive change. I tag a tuning request as an adaptive change too. In my project, I decide which types I accept. Therefore, I define who may submit a request. For instance, I allow IT Service Desk tickets for spec errors. However, I require product marketing to submit scope changes. Thus, I keep submission channels clear.
I follow a step‑by‑step process. First, I capture the request in the change register. Next, I check completeness against the template. Then, I perform an impact analysis. I use traceability to find all affected artifacts. For example, I check requirements, architecture, source code, test cases, and training materials. In addition, I estimate effort and risks. After that, I prepare the analysis for the Change Control Board.
Then, the Change Control Board and I evaluate the results. We decide to accept or reject the change request. I document the board’s decision for traceability and stakeholder agreement. If we accept, I prioritize the change. For adaptive changes, I weigh cost and benefit. For corrective changes, I weigh frequency and effect. Moreover, I schedule accepted changes for a release or project. Finally, I assign implementation responsibility.
I follow clear rejection criteria. For example, I reject changes that cost too much relative to benefit. I reject changes that contradict other requirements; I reject changes that create unacceptable system risk; and I also reject changes not covered by contract. Because clarity matters, I explain the reason when I reject a request.
I act to implement accepted changes. First, I update requirement artifacts carefully. Then, I ensure that the requirements specification returns to a consistent state. I use traceability links to update all related artifacts. Moreover, I run tests and record the tester’s results. Finally, I close the change request only after verification and release assignment.
In practice, I adapt templates and workflows to my company and project. However, I always keep the same essentials. Consequently, I maintain traceability, clarity, and control. Thus, I reduce risk and improve product stability. Moreover, I help stakeholders agree on scope and priorities. Overall, I treat a change request as a controlled, documented, and traceable step in requirements engineering.
