Activity Predecessor Activity Duration in Weeks
A ---- 3
B A 5
C A 7
D B 10
E C 5
F D, E 4

Using the Critical Path Method (CPM), find the critical part, activities, and the date to finish the project (Gantt Chart would help).

I would really appreciate excel screenshots!

Expert Solution

Create network diagram as follows:

List the alternative paths in the network and their respective length.

Length of each path is equal to the sum of times of activities on that path.

Path Length
A-B-D-F 22
A-C-E-F 19

The longest and hence critical path is: A-B-D-F

Date to finish the project = 22 weeks

Gantt chart is following:
