Quizplus · Accepted Answer

The earliest possible completion time for activity E after crashing can be found by determining the total float for activity E and choosing the least value. From Table 7.8, we can see that the total float for activity E is 2 days. Therefore, by crashing activity E for 2 days, we can reduce its duration from 6 days to 4 days, allowing us to complete the project in 13 days (day 1 + 12 days of critical path activities + 0 days of slack). Any further reduction in the duration of activity E would not result in a reduction of the project duration, as the critical path activities are already being completed in the shortest possible time. Therefore, the best choice is to crash activity E by 2 days, resulting in a project completion time of 13 days.
