One of the most common problems that project managers weep about is "unrealistic timelines," a common consequence of clients having set their expectations too high even before the project starts. Ironically, there are occurrences in the duration of a project when a staff is sitting idly, waiting for a colleague to finish so he can start his own task. In this situation, does the project manager shout foul and blame other people? Chances are, as a project manager, he needs to give the project schedule a second look.
