Which date type on tasks can a project manager manually modify?

The planned date on tasks can be manually modified by a project manager because it represents the target date set for when a task is expected to be started or completed. This date is typically established during the project planning phase and may need to be adjusted as the project evolves. Factors such as resource availability, changes in project scope, and unforeseen delays may necessitate these modifications.

The planned date is a key element in project scheduling as it helps the project manager allocate resources effectively and maintain timelines. Having the flexibility to modify these dates allows the project manager to respond proactively to changes in the project environment.

In contrast, the other date types serve different purposes and may have varying levels of restrictions on modifications. The estimated date is based on initial assessments of how long a task will take; the projected date is often auto-calculated by the software based on current progress; and the commit date typically reflects a firm promise or commitment that may not be as easily adjustable. Thus, while the project manager can influence timelines, the planned date stands out as one that can be directly and manually changed based on project needs.
