Scope creep in project management is the (Option B) tendency for a project to grow or change unexpectedly, often leading to challenges in project delivery, such as going over budget or schedule.
Step-by-step explanation:
In project management, scope creep refers to the tendency for a project to grow or change unexpectedly. This usually happens when new features or tasks are added to the project without corresponding increases in resources, time, or budget, which can lead to project overruns and challenges in project delivery. Scope creep is typically considered a risk to be managed, as it can result in projects going over budget, running behind schedule, or resulting in a final deliverable that doesn't meet initial expectations.
