Answer: Scope Creep is the term used to describe what happens when a project's scope increases after it has started.
Explanation: Scope Creep refers to unscheduled changes and are the main reason for failures in a project, whether due to uncontrolled growth or some deviation in planning. This happens when the scope is not documented in the correct way. The more aware you are of the deviations that the project may have, the better the final result will be.
