The introduction of new requirements during the implementation phase can lead to scope creep, which may adversely affect the project's cost and schedule baselines. To manage this, establishing a proper governance structure is essential. This structure would include a change control board or similar entity to evaluate the impact of new requirements and make decisions on their inclusion in the project. This ensures that all changes are assessed for their implications on the project's objectives and resources before being approved1.

Additionally, the Professional in Business Analysis (PMI-PBA) materials emphasize the importance of governance in change management and the role of business analysts in assessing the impact of changes34.
