Quizplus · Accepted Answer

The original project completion time without the delay in activity C is 8 weeks (1 week for A, 2 weeks for B, 4 weeks for D, and 1 week for E and F concurrently). If activity C is delayed by 3 weeks, it will take 6 weeks (3 weeks original time + 3 weeks delay). Since C and D can be done concurrently after A and B, and E depends on the completion of both C and D, the delay in C directly affects the start of E. The new timeline is 1 week for A, 2 weeks for B (concurrent with the start of C), 6 weeks for C, then 4 weeks for D (starts after B, but finishes before C's new duration), then 3 weeks for E (starts after C and D are complete), and finally 2 weeks for F. Thus, the total is 1 + 2 + 6 + 3 + 2 = 14 weeks, making the revised earliest project completion time 12 weeks due to the overlap of activities.
