A project is behind schedule. The Critical Path is A-C-E (20 days). Path B-D-E is 18 days. The project manager decides to crash Activity C by 3 days. What is the new project duration?
Answer options:
A.
17 days
B.
18 days
C.
20 days
D.
15 days
How to approach this question
Check if the critical path shifts. Reduce the crashed path, then compare all paths to find the new longest path.
Full Answer
B.18 days✓ Correct
B
Task 6 involves modifying the schedule. Crashing reduces the duration of one path, but the project duration is determined by the *longest* path. Path 2 (18 days) prevents the project from finishing in 17 days.
Common mistakes
Ignoring the secondary path and assuming the project shortens by the full crash amount.
