8. 8 Rev: 5/05/07 MSE-415: B. Hawrylo Gantt Basics Basically, a timeline with tasks that can be connected to each other Can be created with simple tools like Excel, but specialised tools like Microsoft Project make life easier

9. 9 Rev: 5/05/07 MSE-415: B. Hawrylo Making a Gantt chart Step 1 – list the tasks in the project

10. 10 Rev: 5/05/07 MSE-415: B. Hawrylo Step 2 – add task durations Making a Gantt chart

11. 11 Rev: 5/05/07 MSE-415: B. Hawrylo Step 3 – add dependencies (which tasks cannot start before another task finishes) Making a Gantt chart

12. 12 Rev: 5/05/07 MSE-415: B. Hawrylo The arrows indicate dependencies. Task 1 is a predecessor of task 2 – i.e. task 2 cannot start before task 1 ends. Task 3 is dependent on task 2. Task 7 is dependent on two other tasks Electrics, plumbing and landscaping are concurrent tasks and can happen at the same time, so they overlap on the chart. All 3 can start after task 4 ends. Painting must wait for both electrics and plumbing to be finished. Task 9 has zero duration, and is a milestone Making a Gantt chart

13. 13 Rev: 5/05/07 MSE-415: B. Hawrylo Step 4 – find the critical path The critical path is the sequence of tasks from beginning to end that takes the longest time to complete. It is also the shortest possible time that the project can be finished in. Any task on the critical path is called a critical task. No critical task can have its duration changed without affecting the end date of the project. Making a Gantt chart

14. 14 Rev: 5/05/07 MSE-415: B. Hawrylo MS Project can work out the critical path for you! The length of the critical path is the sum of the lengths of all critical tasks (the red tasks 1,2,3,4,5,7) which is 2+3+1+1.5+2+1 = 10.5 days. In other words, the minimum amount of time required to get all tasks completed is 10.5 days The other tasks (6,8) can each run over-time before affecting the end date of the project

15. 15 Rev: 5/05/07 MSE-415: B. Hawrylo The amount of time a task can be extended before it affects other tasks is called slack (or float). Task 6 can take an extra day and a half before it affects the project’s end date, so each has 1.5 day’s slack. Making a Gantt chart

16. 16 Rev: 5/05/07 MSE-415: B. Hawrylo Critical tasks, by definition, can have NO slack. Tip: If ever asked Can task X’s duration be changed without affecting the end date of the project?, if it is a critical task the answer is always NO! Making a Gantt chart

17. 17 Rev: 5/05/07 MSE-415: B. Hawrylo This PERT chart follows the “Activity on Arrow” style. The tasks are shown by arrows. Task name are shown by letters, in this case. The circles are called nodes. The nodes indicate the start or end of tasks. Task durations are the shown by the numbers. PERT Charts

18. 18 Rev: 5/05/07 MSE-415: B. Hawrylo The path duration is: A-B-C-E-I = 2+3+1+4+3=13 A-B-D-F-I = 2+3+3+3+3=14 A-G-H-I = 2+2+5+3 = 12 Therefore, Completion time = 14 Critical path is A-B-D-F-I Slack time of A-B-C-E-1 = 1 Slack time of A-G-H-1 = 2 PERT Charts

How does the project duration change if task E is shorten to 2? How about 1? What is the best way to shorten the total duration?

23. 23 Rev: 5/05/07 MSE-415: B. Hawrylo Chapter 16 – Managing Projects Team Staffing and Organization The speed at which a team can complete a project is based upon 7 criteria. 1.There are 10 or fewer members of the team. 2.Members volunteer to serve on team. 3.Members serve on the team from the time of concept development to launch. 4.Members are assigned to the team full-time. 5.Members report directly to team leader. 6.The key functions are on the team. 7.Members are located within conversational distance to one another.

24. 24 Rev: 5/05/07 MSE-415: B. Hawrylo Chapter 16 – Managing Projects Project Schedule Merger of the project task and project timeline. 1.Use the DSM or PERT to identify dependencies. 2.Position key milestones. 3.Schedule tasks, considering the project staffing and critical resources. 4.Adjust the timing of the milestone to be consistent with the time required for the tasks.
