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 could be conducted. The activities, immediate predecessors, and times appear in the accompanying table: Activity Immediate Predecessor(s) Time (days) 10 A, D E, F

Solution

The critical path for the activity is B-D-E-G and has a duration of 30 days.

As the acticitie B,D, E and G lie on critical path, they have zero slack.

Slack for A - Latest start time - Earliest start time = 17-2 =15 days

Slack for C = 22-7 = 15 days

Slack for F = 16-1 = 15 days
