Activity | Immediate Predecessor | Optimistic Time | Most Likely Time | Pessimistic Time
A - 2 8 14
B - 8 8 8
C A 9 9 18
D B 11 11 17

Solution determines the critical path in the given case using a table and diagram along with brief explanation to aid understanding.
Determining the Critical Path: Example Problem
Determine critical path and also need help in finding how to reduce the project time by a number of weeks.
Activity Immediate Predecessor Time (in weeks)
A none 4
B A 2
C A 4
D A 3
E B,C 5
F C 6
G D 2
H E 3
I F,G 5
J H,I 7
1. Draw the network diagram.
2. Find the critical path.
3. If activities A and J can't be shortened, yet activities B through I can be shortened to a minimum of one week at a price of $10,000 per week, which activities would you shorten to cut the project by four weeks?
