Complete an Activity-On-Node network diagram based on the scenario below.

Scenario

You're a member of a theater group and have been asked to prepare the schedule, etc. for a play scheduled for Christmas Eve service at one of the local churches in your hometown.

Activity	Predecessor	Time (days)
		Optimistic	Most Likely	Pessimistic
1	None	2	4	6
2	None	5	5	5
3	2	3	5	7
4	1	7	10	13
5	1	11	12	13
6	2,4	5	6	7
7	3	9	10	11
8	3,6	5	7	9
9	4	7	9	11
10	5	3	3	3
11	7	15	17	19
12	8	6	8	10
13	9,10	7	8	15
14	7	12	14	16
15	12,13	16	17	18

Make sure you respond to each of the following five requirements.

1. Construct an AON diagram using the process described in the videos.
2. Calculate the estimated time for each activity using the three estimates provided.
3. Determine the length of all paths and identify which path is the critical path.
4. During the play, one of the activities on the critical path is delayed by one day. Is this serious?
5. Qualitatively discuss the uncertainty of the critical path.
