1. All jobs require two steps. Suppose one worker performs step 1, and one worker performs step 2. In system A jobs must complete step 1 before starting step 2, i.e. the workers are in series. In system B jobs may start steps 1 and 2 independently, i.e. the workers are in parallel. Assume each worker can perform their step at the same rate. a. system A has higher capacity than system B. b. system A has the same capacity as system B
