Enter numbers only.
How to approach this question
Identify the critical path by finding the longest path through the network. Calculate the total duration along this path.
Full Answer
24
Critical path analysis: A→B→D→E = 5+8+4+7 = 24 days. A→C→D→E = 5+6+4+7 = 22 days. The critical path is 24 days.
Common mistakes
Adding all activity durations instead of finding the critical path, or incorrectly calculating the longest path through the network.
