Question

A project has four activities that take 4, 3, 6, and 7 days respectively. What is the total completion time for the project?

3 days, as this is the minimum time
7 days, as this is the maximum time
20 days, as this is the sum of the times
It is not possible to determine the total completion
time from the given information

Answer 1

20 days

Explanation:

To find the total time, we will just add up the days.

4 + 3 + 6 + 7 = 20 days.

Answer 2

(d) not possible to tell from information given

Explanation:

You want to know the total completion time for a project with four activities that take 4, 3, 6, and 7 days.

Completion time

The project completion time will be determined by the dependencies between activities.

Series

If each activity must be completed before the next, then the total time will be 4+3+6+7 = 20 days.

Parallel

If there are no dependencies and all activities can be done in parallel, then the total completion time is 7 days, the time required for the longest activity.

In short, it is not possible to determine the total time from the information given.
