ITPEC FE Morning October 2023 Question 54
ITPEC FE Morning October 2023 — Question 54 of 80
The critical path is the longest path through the project network, determining the minimum project duration.
Calculate each path's total duration:
- •(a) A → B → E → I → L =
2 + 3 + 1 + 2 + 3= 11 days - •(b) A → C → D → E → H → K =
2 + 3 + 1 + 1 + 3 + 2= 12 days - •(c) A → C → F → I → L =
2 + 3 + 3 + 2 + 3= 13 days - •(d) A → C → G → J → L =
2 + 3 + 4 + 2 + 3= 14 days ✅
The longest path is (d) at 14 days, making it the critical path.
Why not others:
- (a) 11 days — shortest path
- (b) 12 days — shorter than (d)
- (c) 13 days — close but 1 day shorter than (d)
Key rule: The critical path is the longest start-to-finish path; it sets the project's minimum duration. Sum every activity on each candidate path and pick the maximum.
