Sometimes project schedules are very informal. They begin as simple lists of dates from e-mails or meetings with clients. Managers do not have complete information on these work items.

In such cases, the PM might just want to enter the dates agreed with the client. In such cases, manual scheduling of tasks is most efficient way of scheduling projects.
