Clues:

1- The time unit is weeks

2- Durations are: 1, 2, 3, 4, 5, 6, 7.

3- No two activities have the same duration.

4- There exists only one critical path, and it is the largest possible number given the possible durations shown.

5- The slack times of the seven activities are: 0, 0, 0, 3, 6, 8, 8

6- Activity E has the smallest amount of slack that is greater than zero.

7- The early finish (EF) time for activity A is four weeks, and this does not equal the latest finish (LF) time. (Note: There is no negative slack in the network.)

8- The slack in activity C is eight weeks.

9- The duration of activity F is greater than the duration of activity C by at least two weeks.

Requirements: 1. For each activity calculate: ES, EF, Duration, LS, LF, and Slack. 2. This assignment can be done in a group of four. 3. Make a PowerPoint with animation and explanation to show how you solved the puzzle. Puzzle: A project manager discovers that his team has neglected to complete the network diagram for the project.
