A project manager is managing a few innovation projects with a high level of uncertainty.

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.
