Expected time= (a+4m+b)/6
A (12+16*4+25)/6= 16.8
B (7+14*4+22)/6= 14.2
C 5+4*10+14)/6= 9.8
D 15+4*18+25)/6= 18.7
E 8+4*12+18)/6= 12.3
F 9+4*12+15)/6= 12
G 18+4*22+29)/6= 22.5
H 15+4*19+27)/6= 19.7
3 Conduct a forward pass to compute early start and early finish times, and time
E.F =E.S+DURATION
4
Conduct a backward pass to compute late start and late finish times.
L.S= L.F-DURATION
5 Compute activity slacks.
