What is the primary purpose of project scope management?

Correct answer: To define and control what work is included in the project and what is not

Option A is correct because project scope management encompasses the processes required to define what work is and is not included in the project, and to control changes to that boundary, ensuring the project delivers exactly what was agreed upon and prevents scope creep. Option B is incorrect because managing project team conflicts is addressed by project resource management and interpersonal skills, not scope management. Option C is incorrect because minimizing costs is the concern of project cost management, not scope management, although controlling scope does indirectly support cost control. Option D is incorrect because scheduling all project activities is the domain of project schedule management, which uses the defined scope as input but is a separate knowledge area.
