How should changes to requirements approved during a project be documented?

• A. By verbal agreement
• B. By a memo to vendor
• C. By posting on a bulletin board
• D. Through a formal change control process with updated SOW/contract amendments and impact assessments

Answer: (D)

Managing changes to approved requirements relies on a formal change control process that records updates in the SOW or contract and includes an impact assessment. This approach ensures every modification is evaluated for its effect on scope, schedule, cost, and quality, and that all stakeholders formally approve before work proceeds. Having updated contractual documents and a documented impact analysis creates a traceable record, maintains alignment with the project baseline, and provides an auditable trail for governance. Verbal agreements, memos to vendors, or posting notices are informal and lack the required approvals and version control, which can lead to miscommunication and scope creep. A formal process, by contrast, ensures changes are proposed, analyzed, approved or rejected by the right authorities, and properly reflected in the contract and project plan.
