One of the new features introduced in Project 2010 is manual scheduling. Prior to 2010, all project tasks were automatically scheduled, meaning that as soon as you put it in the schedule, MS Project would try and schedule it for you. Whilst most people get used to this behaviour, others prefer more control over the schedule, hence why manual scheduling was introduced. This feature allows the user to enter tasks where they want in the WBS and not have to provide meaningful duration or work data for the task to be scheduled.
