To manage scope creep effectively, consider the following best practices:

1. **Clearly Define Scope**: At the beginning of the project, define and document the project's scope in detail, including deliverables, timelines, and objectives.
2. **Change Control Process**: Establish a formal change control process that requires any changes to the scope to be evaluated and approved. This should include assessing the impact on budget and timeline.
3. **Stakeholder Engagement**: Regularly communicate with stakeholders to ensure their expectations are aligned with the project scope to prevent misunderstandings.
