1. You are in charge of planning and coordinating next falls sales management training program for your company. You have never done this before, but you decided to use the lessons from your class to develop a table of tasks to be done, their immediate predecessors, and the most pessimistic, optimistic, and frequent times for each task. The table you developed is below:

Task	Immediate Predecessor	Task completion time estimate (weeks)			Mean	Variance
		Optimistic	Most probable	Pessimistic
A	--	1.5	2	2.5	2	0.02778
B	A	2	2.5	6	3	0.44444
C	--	1	2	3	2	0.11111
D	C	1.5	2	2.5	2	0.02778
E	B,D	0.5	1	1.5	1	0.02778
F	E	1	2	3	2	0.11111
G	B,D	3	3.5	7	4	0.44444
H	G	3	4	5	4	0.11111
I	F,H	1.5	2	2.5	2	0.02778

1. On the next page, draw the CPM/PERT diagram, filling in the values for the task times, earliest and latest start and finish.

2. What is the expected project completion time?

3. What is the critical path?
