Scope management is the process of defining and controlling what is included and excluded in a project. It ensures that all necessary work is completed while avoiding unnecessary tasks that can lead to project delays and increased costs. This involves creating a clear project scope statement, which outlines the project's goals, deliverables, and boundaries. Effective scope management also includes monitoring and adjusting the project scope as needed. This is done through scope change control, which helps manage any changes that may arise during the project lifecycle. By maintaining a well-defined scope, project managers can enhance project success and stakeholder satisfaction.
