According to the PMBOK Guide, when a project manager faces a change request that affects the project scope, schedule, cost, or quality, they should first evaluate the impact of the change and then follow the change control process. The change control process involves reviewing the change request, analyzing the options, obtaining approval, and updating the project management plan and other documents. One of the options that the project manager can consider is to negotiate with the team and other stakeholders to find a feasible solution that can accommodate the change request without compromising the project objectives. This option requires effective communication, collaboration, and conflict resolution skills from the project manager and the team. Asking the team to accelerate the iterations and avoid interruptions (option A) is not a realistic or sustainable strategy, as it may lead to burnout, quality issues, and scope creep. Verifying team performance and asking for improvement during daily standup meetings (option C) is not a direct or proactive way to address the change request, as it may imply that the team is not performing well or that the project manager is micromanaging them. Recommending that the project sponsor increases the budget to bring new resources (option D) is not a viable option, as it may not be approved or feasible, and it may also introduce new risks and challenges to the project.
