What is referred to as "scope creep" in project management?

Scope creep refers to the gradual expansion of a project's scope beyond its original parameters without proper documentation, approval, or a corresponding increase in resources or time. This often happens when new features or requirements are added after the project has started, and typically occurs without formal change management processes in place to evaluate and control these alterations.

Such changes can negatively impact the project by leading to cost overruns, schedule delays, and resource strain, as the initial project plan no longer accurately reflects what's required to meet new expectations. Proper project management practices emphasize the importance of documenting any changes to the scope and involving the necessary stakeholders for approval to maintain project integrity and ensure successful completion.
