Which statement is true regarding projected and estimated dates on tasks?

The statement that the estimated and projected dates of tasks cannot be manually modified is accurate because these dates are typically derived from different sources and processes within project management. The estimated date is often based on the original planning and resource allocation, while the projected date may be influenced by current progress, resource availability, and any changes in the project's timeline as it unfolds.

The design of many project management tools, including Adobe Workfront, is to ensure that these dates are automatically calculated based on the task’s attributes and dependencies. In this structure, the intent is to create a clear, reliable way to track progress without manual interference that could lead to inconsistencies or misunderstandings in project timelines.

Therefore, the adherence to this automated and systematic approach helps project managers to maintain an accurate view of timelines, allowing them to adjust project planning and resources efficiently.
