"The project schedule, especially at the beginning of the project, is a promise on the part of the project team to try to meet their estimates/guesses. The only thing you know about the project schedule is that the way you've laid it out is the one way it won't happen. Life happens and the project schedule can't reflect the server going down, the thunderstorm that took out power in one sub-project's building, or the person who had an emergency appendectomy. All those events happen on projects, and you can't know at the beginning when you schedule a project what will happen. The schedule is how you hope the project will unfold -- but it's certainly no guarantee."
