Th possible paths and their corresponding durations as follows :
A-C-F = 1 + 9 + 2 = 12 weeks
A-B-E-F = 1 + 3 + 5 + 2 = 11 weeks
Out of above , AC-C-F has the longest duration and therefore is the CRITICAL PATH.
Since, the total project completion time is same as duration of the critical path , the project completion time will be 12 weeks
It is to be noted that Slack time for all activities lying on the critical path will be ZERO
Therefore, slack time for activities A/C/F will be ZERO
Slack time for activity B as well as E
= Duration A-C-F – Duration A-B-E-F
= 12 – 11 weeks
= 1 week
