Your task for this assignment is to create a network diagram for two projects. The activity, immediate predecessor and duration are given. You are to layout-long-hand or using some software-a network diagram for each project. For each diagram conduct a forward and backward pass, calculate the slack, and identify the critical path. When noting your early start, early finish, late start, late finish and slack, please use the format provided.
