The task times, shown in minutes, are the times that it takes one worker to perform that task for one unit of product. This line is staffed with six workers, two of whom are assigned to workstation D$.$ Assume that each of the tasks $($tasks A through E$)$ are never split among multiple workers. Thus, the two workers doing task d work on individual units, each doing all of task D on the particular unit on which he or she is working. Assume that there is ample equipment so that all workers can perform their tasks$\mathrm{.}15$ mins.

$1.$ Assuming workers can be cross$-$trained, how could you increase the system capacity and labor utilization without adding an additional worker?

$2.$ Refer to the Process Diagram for a Five$-$Task Line. Assume that the process is running in steady$-$state at bottleneck pacing. If you were to add a worker to Task C$,$ what would the overall labor utilization be$?$

$3.$ Refer to the Process Diagram for a Five$-$Task Line. Assume the process is running in steady$-$state at bottleneck pacing, what is the capacity utilization of task D$?$

$4.$ Refer to the Process Diagram for a Five$-$Task Line. Assume the process is running in steady$-$state at bottleneck pacing, what is the capacity utilization of task B$?$
