During a project, the project manager discovers there is insufficient time allotted for quality control. The project manager prepared to submit a revised schedule to the CCB.
Given the attached chart, which of the following is the critical path if one day is added to each task for quality control?
A. 12 days
B. 16 days
C. 17 days
D. 22 days
Correct answer is:
(Task 1 +1 day) + (Task 3 + 1 day) + (Task 4 + 1 day) + lag + (Task 5 + 1 day) =
2 + 4 + 7 + 2 + 3 = 18 days.
I think it is B, 16 days.
