344 Chapter 10 . Project Scheduling INTEGRATED PROJECT Developing the Project Schedule Develop an in-depth schedule for your initial project based on the Work Breakdown Structure you have completed. You will need to complete several activities at this stage: (1) create an activity precedence diagram showing the network logic for each project activity you have identified; (2) prepare an activity duration table showing optimistic, likely, and pessimistic activity times for each task; and (3) create both the network diagram and Gantt charts for your project, indicating the critical path and all critical activities, total project duration, and all activities with float. As you prepare the activity precedence diagram, consider: 1. Have we identified opportunities to create parallel paths or are we placing too many activities directly in a serial path? 2. Is our logic correct for identifying preceding and subsequent activities? 3. Are there some clear milestones we can identify along the precedence diagram? As you prepare the activity duration table, you might wish to set it up along the following lines: Duration Activity Optimistic Likely Pessimistic Est.
