Activity	Time (months)	Immediate Predecessor
A	1	None
B	3	A
C	4	A
D	2	B,C
E	2	B
F	2	D,C

Paths	Time Taken
A-B-E	1+3+2=6
A-B-D-F	1+3+2+2=8
A-C-D-F	1+4+2+2=9
A-C-F	1+4+2=7

Critical Path is A-C-D-F with 9 months required.

The completion time required is 9 months, i.e. time taken for critical paths.

Based on this outcome, the project cannot be completed in time for UIW to use this facility in five months. The minimum time required is 9 months (time required for critical path).

Question #2 --- If the variance for the project is 4 months, what is the project time at the 90^th percentile, what is the project time at the 30^th percentile, and what is the probability that the facility will be ready in 5 months?
