Jennie, A timeline also assigns a very specific responsible person for the action required. That can sometimes be a big problem with program development. A key leader to oversee the project and key assignments that this person can point toward when the ball is dropped. Often times, it is a peer that is assigned to direct others to do their part. In a matrix organization that lacks egos, this works. In a strict hierarchy with egos, this is more difficult. Christopher Nickell
