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: 

Activity	Immediate Predecessor(s)	Time (days)
A	-	2
B	-	6
C	-	2
D	B	10
E	A, D	3
F	C	5
G	E, F	12

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 = 31 days. 

d) Slack time for each of the activities is: 

Answer 1

SLACK :

A = LS-ES = 15 -1 = 14 Days

B= 1-1 = 0

C=15-1 = 14 Days

D = 7-7 =0

E=17-17 =0

F=15-3 =12 Days

G=20-20 = 0

Noted: Slack will be always 0 days for the activites on the critical path, hence the slack for activites for B,D,E,G are 0
