Greg is trying to perfect the business model before making it into a franchise. He wants to maximize the productivity of his staff, as well as serve customers well in a timely fashion. One area of concern is the drive$-$thru operation during the $11$:$30$ a$.$m$.$ to $12$:$30$ p$.$m$.$ lunch hour. The process of fulfilling an order involves fulfilling the tasks listed in the table. Greg is interested in getting a better understanding of the staffing patterns that will be needed to operate his restaurant. After taking a course in operations management at the university, he knows that fulfilling a customer order at SPS is very similar to operating an assembly line. He has also used the POM for Windows software before, and wants to apply it for examining different demand scenarios for serving his customers.
