Which of the following best describes 'scope management'?

Scope management refers to the processes involved in defining and controlling what is and is not included in a project. The primary focus of scope management is to ensure that a project's deliverables align with the goals and requirements set at the project's inception, thereby avoiding scope creep and unplanned changes.

The correct choice emphasizes the importance of controlling changes to the project's scope. This involves establishing procedures for how changes are requested, reviewed, and implemented. Managing scope effectively ensures that stakeholders have a shared understanding of the project's boundaries and helps to maintain focus on the agreed-upon objectives.

The other choices, while related to project management, do not capture the essence of scope management as accurately. Identifying and managing stakeholder needs is an important aspect of stakeholder management; ensuring deadlines is a function of time management; evaluating quality pertains more to quality management processes. Each of these areas is crucial for project success, but they serve different purposes compared to scope management, which is specifically about defining and controlling project boundaries.
