Tanouye Corporation keeps careful track of the time required to fill orders.Data concerning a particular order appear below: The throughput time was:

A) 4.1 hours
B) 12.9 hours
C) 25.6 hours
D) 21.5 hours

The throughput time includes the time it took to process the order (4.5 hours), the wait time in the queue (5.5 hours), and the time it took to receive the order (2.9 hours). Therefore, the total throughput time is:

4.5 hours + 5.5 hours + 2.9 hours = 12.9 hours

Thus, the correct choice is B.

Throughput time = Process time + Inspection time + Move time + Queue time
= 1.6 hours + 0.4 hours + 2.1 hours + 8.8 hours = 12.9 hours
