A project manager is receiving many requests for changes to a project. Which of the following did the project manager fail to complete?

Proper project team selection primarily impacts the efficiency and quality of project execution, not directly the initial influx of change requests related to project scope or requirements.

Subject Matter Expert (SME) solicitation helps in gathering accurate technical requirements but is a component of, and not a substitute for, a comprehensive stakeholder analysis to manage all interests.

Milestone scheduling is a planning activity for tracking project progress against key dates and does not directly address the root cause of excessive change requests, which often relate to scope definition.

A thorough stakeholder analysis identifies all relevant stakeholders, their interests, expectations, and potential influence, which helps in defining a clear project scope and managing expectations, thus significantly reducing the volume of change requests during project execution.
