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

The statement indicating that the estimated and projected dates of tasks cannot be manually modified is accurate because it reflects a core functionality of Adobe Workfront in terms of task management. In the platform, estimated dates are typically derived from the initial planning phase and are set based on the team's forecasts regarding how long a task will take to complete.

On the other hand, projected dates are dynamically adjusted based on real-time progress against the task as work is completed. This means that while users can interact with the system to manage tasks, manually changing these specific dates directly might not align with the system's intended use, which relies on automated updating for better accuracy in project timelines. Therefore, these dates function with an automated logic to ensure consistency in project scheduling and resource allocation, serving to reduce errors that might occur if users were allowed to modify these dates arbitrarily.

This automated approach can help teams maintain a clear understanding of deadlines and expectations without the complications that may arise from manual adjustments, thereby enhancing workflow efficiency.
