  1. MS Project Concepts Dr. Greg Neal CIS 480 Systems Analysis and Design Dr. Neal CIS 480

  2. Pert Network Dr. Neal CIS 480

  3. Gantt Chart 1,2 & 3 all start at beginning Dr. Neal CIS 480

  4. Task List Late Start Slack Difference Early-Late Early Start Critical Path Dr. Neal CIS 480

  5. Calculation of EarlyStart,LateStart,Slack • Task Three (3 days) • EarlyStart (Project Start on 6/1/06) • LateStart = Task 7 LateStart – Task 3 duration: 6/2/06 • Task Seven (6 days) • Task 7 StartFinish predecessor of Task 3 • EarlyStart =Task 3 Finish 6/5/06 + 1 day: 6/6/06 • LateStart = Task 9 LateStart – Task 7 duration: 6/7/06 • Task Nine (3 days) • Task 9 StartFinish predecessor of Task 7 • EarlyStart = Task 7 Finish 6/13/06 + 1 day: 6/14/06 • LateStart = Task 10 Start – 3 days: 6/15/06 Forward Calculation Slack 1 day Backward Calculation Dr. Neal CIS 480

  6. Task Dependencies • Finish-to-Start (FS) • Task B cannot start until task A finishes • Start-to-Start (SS) • Task B cannot start until task A starts (both start the same time) • Finish-to-Finish (FF) • Task B cannot finish until task A finishes (both finish at the same time) • Start-to-Finish (SF) • Task B cannot finish until task A starts Dr. Neal CIS 480

  7. Dependency Gantt Examples FinishStart(FS) StartStart(SS) StartFinish(SF) FinishFinish(FF) Dr. Neal CIS 480
