On page 96 Jonah notes that running a non-bottleneck machine to its maximum is an act of maximum stupidity. This is because non-bottlenecks create more units per hour than bottlenecks thereby creating inventory (which is against the goal). Consider the following table:

If the Milling AND Fabrication departments both run at full-speed, how much WIP inventory will build up between Fabrication and the NCX-10 in one eight-hour shift?

\begin{tabular}{|l|c|c|c|} \hline Department & Status & Max Capacity (uph) & ProductionSchedule \\ \hline Milling & Non-bottleneck & 22 uph & ??? uph \\ \hline Fabrication & Non-bottleneck & 15 uph & ??? uph \\ \hline NCX-10 & Bottleneck & 10 uph & 10 uph \\ \hline Assembly & Non-bottleneck & 17 uph & ??? uph \\ \hline \end{tabular}
