Free PMI Project Management Professional (PMP) Practice Question

The primary reason for a project manager to modify the project schedule is to address unforeseen changes or variations that may affect the project's timeline. This aligns with adaptive project management methodologies that expect and incorporate flexibility. Modifications might be triggered by changes in project scope, identified risks materializing, or other external factors. It is critical for maintaining alignment with project goals and objectives. Alternatives such as sticking rigidly to the original schedule or only making changes annually do not allow for the responsiveness required in a dynamic project environment.
