A project defined with list of activities and required times for completion: Activity No. ActivityExpected completion time Dependency 1.Specification5 days- 2.XML configurator6 days1 3.Setup code and dbase7 days1 4.Test XML2 days2,3 5.Homepage design/coding6 days4 6.Contact agents5 days5 7.Transfer properties3 days4 8.8.Testing portal/ SEO1 day5,7 Portal is functional a. Draw a PERT chart for the activities. b. Calculate the earliest expected completion time. c. Show the critical path.

4 4 PERT Chart (cont’d) a.Draw a PERT chart for the activities. Using information from the table, show the sequence of activities

5 5 PERT Chart (cont’d) b. Calculate the earliest expected completion time. 1. Using information from the table, indicate expected completion time for each activity Calculate earliest expected completion time for each activity (T E ) and the entire project. Hint: the earliest expected completion time for a given activity is determined by summing the expected completion time of this activity and the earliest expected completion time of the immediate predecessor. Rule: if two or more activities precede an activity, the one with the largest T E is used in calculation (e.g., for activity 4, we will use T E of activity 3 but not 2 since 12 > 11). T E = 5 T E = 11 T E = 12 T E = 14 T E = 20 T E = 19 T E = 22 T E = 23

6 6 PERT Chart (the end) T E = 5 T E = 11 T E = 12 T E = 14 T E = 20 T E = 19 T E = 22 T E = 23 c. Show the critical path. The critical path represents the shortest time, in which a project can be completed. Any activity on the critical path that is delayed in completion delays the entire project. Activities not on the critical path contain slack time and allow the project manager some flexibility in scheduling. 7
