A stakeholder wants to add another requirement to the deliverable. Which of the following will the project manager do to determine the change's effect on the project?

Performing an impact analysis is the specific process where a project manager evaluates how a proposed change, such as a new requirement, will affect various aspects of the project, including its scope, schedule, budget, resources, and risks. This analysis provides the critical information needed to make an informed decision about whether to approve or reject the change.

Identifying a change is merely recognizing that a change has been proposed, but it does not determine the specific effects of that change.

Coordinating with stakeholders to select a course of action typically occurs after the impact analysis has been completed, to discuss the findings and decide on the best path forward.

Filling out a change control form is a documentation step for the change request, which may precede or accompany an impact analysis, but it does not by itself determine the change's effect.
