Scope creep is defined as:

		The duration between the end of the task and the beginning of the next one.
		Breaking down the project's major deliverables into smaller, more manageable components to make project control easier.
		The uncontrolled and growth of the project scope resulting from incremental change to requirements without consideration of the impact on resources or schedules.
		The temporary transfer of a creepy person from his or her normal duty to another assignment, such as a project.
