Suppose Billy's Hamburger Barn redesigns the process described in problem 11 so there are now two attendants. The ﬁrst attendant takes the order. Once this step is ﬁnished, the ﬁrst attendant then takes the money, and the second one gathers up and bags the food. If two of the process steps can now run in parallel (gathering the food and taking the money), what is the new minimum cycle time? What is the longest cycle time? What potential problems could arise by splitting the process across two individuals?
