Pert Charts

CPM: Critical Path Method Alternative to PERT Dupont 1957 Graphical view of project Predicts time required to complete Shows which activities are critical to maintaining the schedule

Planning: PERT and CPM 1. Identify the specific activities and milestones. 2. Determine the proper sequence of the activities. 3. Construct a network diagram. 4. Estimate the time required for each activity. 5. Determine the critical path. 6. Update the PERT chart as the project progresses. 1. Specify the individual activities. 2. Determine the sequence of those activities. 3. Draw a network diagram. 4. Estimate the completion time for each activity. 5. Identify the critical path (longest path through the network) 6. Update the CPM diagram as the project progresses.

Gantt Charts Milestone charts Invented by Harvey Gantt in 1916 Advantages Less detailed Amenable to management overlays

What you should be able to tell from your project plan What is Joe working on this week? Who can help me if I run into trouble? If I have to choose an activity to be late, which one will impact the project more?

Inspections Introduced by Michael Fagin in 76 (IBM Systems Journal) Formalized process Specific roles and steps Heavy preparation and follow-up Used for documents and code
