What is meant by 'scope creep' in project management?

In project management, 'scope creep' refers to the gradual expansion of a project's scope without corresponding adjustments in resources, time, or budget. This often occurs when new features or requirements are added to a project after the initial planning phase has been completed. As a result, the project can experience delays in its schedule since the team must accommodate these additional tasks or changes, which can lead to a misalignment between the project’s original objectives and what is being delivered.

The phenomenon is problematic because it can lead to increased costs, stretched resources, and ultimately decreased satisfaction among stakeholders if the project does not meet its original timeline or budget guidelines. Recognizing this term is essential for project managers to maintain control over project changes and to effectively communicate with stakeholders about the implications of expanding the project scope.
