What does 'scope creep' refer to in project management?

Scope creep refers to the gradual expansion of a project's scope without proper adjustments to time, cost, or resources. It usually occurs when new features or requirements are added after the project has already commenced, often without formal approval or assessment of the impact these changes will have on the overall project plan. This can lead to delays, budget overruns, and resource strains, as the project's original boundaries are continually pushed outward.

Understanding scope creep is vital for project managers to maintain control over a project’s objectives and deliverables. Effective scope management includes establishing a clear project scope at the start, routinely reviewing changes, and applying proper change management processes to ensure that any alterations are agreed upon by stakeholders and are adequately reflected in project planning.

The other options do not accurately define scope creep. A planned reduction in project activities suggests a deliberate process, which is contrary to the nature of scope creep. The assessment of completed project tasks and methods to improve project feasibility do not pertain to the uncontrolled changes that occur in scope creep.
