Consider a project that requires the completion of 7 tasks, as follows:
o Tasks A and B can begin simultaneously at the beginning ("time zero").
o Task C can only begin after task B is completed.
o Task D can only begin after task A is completed.
o Task E can only begin after task A is completed.
o Task F can only begin after task E is completed.
o Task G can only begin after tasks C and D are completed.
The expected durations (in days) of each task are as follows: A=15; B=15; C=10; D=10; E=30; F=20; G=40.
What is the expected completion of the whole project?
A. 50 days
B. 60 days
C. 70 days
D. 75 days
Consider the project from the previous question with the added complexity that the actual completion time of each task will be:
A) 15+ RANDBETWEEN(-8,8)
B) 20+ RANDBETWEEN(-8,8)
C) 10+ RANDBETWEEN(-8,8)
D) 10+ RANDBETWEEN(-8,8)
E) 30+ RANDBETWEEN(-8,8)
F) 20+ RANDBETWEEN(-8,8)
G) 40+ RANDBETWEEN(-8,8)
Using PERT, what is the expected completion time of the project?
A. 50 days
B. 60 days
C. 70 days
D. 75 days
