16. The owner of two pizza parlors located in adjacent towns wants to computerize and integrate sales  transactions  and  inventory  management within and between both stores. The point-of-sale component  must  be  easy  to  use  and  flexible enough  to  accommodate  a  variety  of  pricing strategies and coupons. The  inventory management,  which  will  be  linked  to  the  point-of-sale component,  must  also  be  easy  to  use  and  fast. The systems at each store need to be linked so that sales and inventory levels can be determined instantly for each store and for both stores combined. The owner can allocate $40,000 for hardware and $20,000 for software and must have the new system operational in three months. Training must be short and easy. Briefly describe three alternative systems for this situation and explain how each would meet the requirements and constraints.  Are  the requirements  and  constraints realistic? Why or why not?

17. Compare the alternative systems from Problem and Exercise 16 using the weighted approach demonstrated in Figure 7-19. Which system would you recommend? Why? Was the approach taken in this and Problem and Exercise 16 useful even for this relatively small system? Why or why not?
