In projects with high levels of uncertainty, especially those that are innovative in nature, it is beneficial to increase the number of iterations. This allows for more frequent reassessments and adjustments, which can help in managing change requests more effectively. By breaking down the project into smaller parts and reassessing at the end of each iteration, the project manager can incorporate necessary changes in a controlled manner, thus reducing the overall number of change requests.

The PMBOK Guide outlines the iterative approach as a means to manage and control projects with high uncertainty1. It suggests that iterative cycles allow for continuous improvement and adaptation, which is crucial for innovation projects2. The Professional in Business Analysis materials also support this approach, emphasizing the importance of iterative review and adaptation in response to change34.
