To effectively manage scope creep in project management, here are some best practices:

1. **Define a Clear Scope**: At the beginning of the project, clearly define the project's scope, including goals, deliverables, and boundaries. This should be documented and agreed upon by all stakeholders.
2. **Involve Stakeholders**: Engage stakeholders in the initial planning phase to ensure their needs are incorporated into the project scope. Continuous stakeholder involvement helps in managing expectations.
3. **Change Control Process**: Implement a formal change control process. This should include procedures for submitting change requests, assessing their impact on the project, and obtaining approval before changes are made.
