An ongoing project requires several parts manufactured at an outside vendor. If the vendor has
sufficient quantity and can still ship today, the parts should be received in five days; although in
most cases an order of this size requires ten days. Allowing for an upcoming holiday and some
potential bad weather the shipment could take up to twenty-one days. Using the PERT method,
which of the following is the correct time estimate for a parts delivery?
A.
10 days
B.
11 days
C.
21 days
D.
36 days
PERT uses six metrics. Questions only gives three. Therefore, must use the “Three points” method, which is ( Optimistic + Most Likely + Pessimistic ) / 3 = 12. Answer B is closest.
