Question: A PERT chart includes the following information:

Activity Immediate Predecessor T/o T/m T/p
A NONE 3 6 10
B A 4 9 14
C B AND A 1 4 8
D B AND C 5 7 10
E C 2 5 8
F D AND E 2 5 9
  1. Draw a network and label each activity with is expected time and variance.
  2. Calculate the expected completion time of the project.
  3. What is the probability that the project will be completed in 30 days?
  4. Are the PERT assumptions used to calculate the probability in part "C" realistic in this case? Why or why not?
  5. What is the effect of the large variance in activity B?
