Question 1

A project has the following network diagram with activity durations:

Activity A: 4 days (no predecessors)
Activity B: 6 days (predecessor: A)
Activity C: 3 days (predecessor: A)
Activity D: 5 days (predecessors: B, C)
Activity E: 2 days (predecessor: D)

What is the total project duration in days? (Enter numbers only)

Accepted Answer

Calculate the critical path by finding the longest path through the network. Path A-B-D-E = 4+6+5+2 = 17 days. Path A-C-D-E = 4+3+5+2 = 14 days. The critical path is 17 days.
