Question

Each X requires 2 of component Y; each Y requires 4 of part Z. The lead time for assembly of X is 1 week. The lead time for the manufacture of Y is 1 week. The lead time for the procurement of Z is 6 weeks. The cumulative lead time for X is _____ weeks.

a. 48
b. 7
c. 8
d. 10

Answer 1

Answer: C.

Explanation:

The cumulative lead time for manufacturing is equal the manufacturing Lead Time + Procurement Lead Time (for raw materials, components, and subassemblies) + Shipping Lead Time

Therefore cummulative lead time = 1+6+1 = 8 .

Shipping time is not considered or assumed to be zero .
