Using information from the table, indicate expected completion time for each activity. 5 6 7 2 6 53 1 2. 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

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
