What are the dependencies between Parent Tasks and Subtasks?

• You cannot mark a Parent Task as Completed before completing its Subtasks.
• The Start Time and End Time of a Parent Task are set automatically based on the Start Time and End Time of its Subtask(s). The Start Time of the Parent Task is set to the Start Time of the Subtask that starts first, and its End Time is set to the End Time of the Subtask that ends last.
• In the case where a Parent Task has multiple Subtasks, each of the Subtasks is independent of the other. Each Subtask can have a separate Previous Task.
