Question

Roger Ginde is developing a program in supply chain management certification for managers. Ginde has listed a number of activities that must be completed before a training program of this nature could be conducted. The activities, immediate predecessors, and times appear in the accompanying table:

A) The critical activities for the leadership training program development project are?

B) The project length for the leadership training program development project?

D) Slack time for each of the activities is(EACH INDIVIDUAL SLACK TIME)?

Activity Immediate Predecessor(s) Time(days) A - 3 B - 6 C - 2 D B 10 E A, D 3 F C 6 G E, F 8

Explanation / Answer

The precedence diagram of activities as follows :

A-E-G = 3 + 3 + 8 = 14days

B-D-E-G = 6 + 10 + 3 + 8 = 27 days

C-F-G = 2 + 6 + 8 = 16 days

Out of above , activities B-D-E-G has the longest duration of 27 days and hence forms the critical path for the project

Slack time of activity A

= Duration B-D-E-G - Duration A-E-G

= 27 – 14

= 13 days

Slack time of C, F

= Duration B-D-E-G – Duration C-F-G

= 27 – 16

= 11 days
