Scope Creep is a concept picked up from the Project Management domain. It is defined as the addition of features and/or functionality during the life cycle of the project (over and above the scope that was originally signed off) without doing the due diligence on time, cost, resources or without the customer approval.
Scope creep happens to be one of the prominent reasons for project failures.
