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: Activity Immediate Predecessor(s) Time (days) B A, D C E, F This exercise contains only parts b, c, and d. b) The critical activities for the leadership training program development project are B - D - E - G. c) The project length for the leadership training program development project = 28 days. d) Slack time for each of the activities is: ABCDEFG Activity A Slack Time ∞ or w w w 10
