Question $1$

A process requires $6$ tasks, A$,$ B$,$ C$,$ D$,$ E and F$,$ that must be performed in that order. Currently there are $3$ employees that are equally

skilled at each task. Employee $1$ is assigned tasks A and B$,$ employee $2$ is assigned tasks C and D and employee $3$ is assigned tasks E

and F$.$ The task times $($all in seconds$)$ are given in the process table below. For example, task A requires $90$ seconds.

Suppose the system started without any work in process inventory $($i$.$e$.,$ an empty system$).$ How long would this process take to

produce $12$ units $($in seconds$)?$
