FSE 100 Extra Credit (20 points) Instructions: Read the description below and work through the design process to build an automated waste sorting system. Turn in the following deliverables in one document, typed: 1. Problem Statement – 1 point 2. Technical System Requirements (at least 3 complete sentences using “shall”) – 3 points 3. Judging Criteria (at least 3, explain why you chose them) – 2 points 4. AHP – 2 points 5. Summaries of your 3 design options (paragraph minimum for each option) – 3 points 6. Design Decision Matrix – 3 points 7. Orthographic Drawing of your final design (3 projections required) – 3 points 8. Activity Diagram of how your sorter functions – 3 points Description: The city of Tempe waste management has notified ASU that due to the exceptional effort the Sundevil students have made in the sustainability area, ASU has been contributing three times the amount of recyclable materials than what was predicted on a monthly basis. Unfortunately, due to the immense amount of materials being delivered, the city of Tempe waste management has asked for assistance from ASU prior to picking up the recyclable waste. They have requested that ASU implement an automated waste sorting system that would pre-filter all the materials so the city of Tempe can collect the materials based on one of three types and process the waste much faster. ASU has hired you to design an automated sorter, but due to the unexpected nature of this request, ASU prefers that this design be as simple and inexpensive to build as possible. The city of Tempe would like to have the waste categorized as either glass, plastic, or metal. Paper will not be considered in this design. Any glass that is sorted in your device needs to stay intact, and not break. Very few people will be able to monitor this device as it sorts, so it must be able to sort the items with no input from a user, as quickly as possible. This design cannot exceed 2m in length, width, or height, but the weight is unlimited. ASU is not giving any guidance as to the materials you can use, so you are free to shop for whatever you’d like, but keep in mind, the final cost of this device must be as inexpensive as possible. Submit through Blackboard or print out your document and turn it in to me no later than the date shown on Blackboard.

SUPPLY CHAIN MANAGEMENT AT BOSE CORPORATION Bose Corporation, headquartered in Framingham, Massachusetts, offers an excellent example of integrated supply chain management. Bose, a producer of audio premium speakers used in automobiles, high-fidelity systems, and consumer and commercial broadcasting systems, was founded in 1964 by Dr. Bose of MIT. Bose currently maintains plants in Massachusetts and Michigan as well as Canada, Mexico, and Ireland. Its purchasing organization, while decentralized, has some overlap that requires coordination between sites. It manages this coordination by using conference calls between managers, electronic communication, and joint problem solving. The company is moving toward single sourcing many of its 800 to 1,000 parts, which include corrugated paper, particle board and wood, plastic injected molded parts, fasteners, glues, woofers, and fabric. Some product components, such as woofers, are sourced overseas. For example, at the Hillsdale, Michigan, plant, foreign sourcing accounts for 20% of purchases, with the remainder of suppliers located immediately within the state of Michigan. About 35% of the parts purchased at this site are single sourced, with approximately half of the components arriving with no incoming inspection performed. In turn, Bose ships finished products directly to Delco, Honda, and Nissan and has a record of no missed deliveries. Normal lead time to customers is 60 working days, but Bose can expedite shipments in one week and airfreight them if necessary. The company has developed a detailed supplier performance system that measures on-time delivery, quality performance, technical improvements, and supplier suggestions. A report is generated twice a month from this system and sent to the supplier providing feedback about supplier performance. If there is a three-week trend of poor performance, Bose will usually establish a specific goal for improvement that the supplier must attain. Examples include 10% delivery improvement every month until 100% conformance is achieved, or 5% quality improvement until a 1% defect level is reached over a four-month period. In one case, a supplier sent a rejected shipment back to Bose without explanation and with no corrective action taken. When no significant improvement occurred, another supplier replaced the delinquent supplier. Bose has few written contracts with suppliers. After six months of deliveries without rejects, Bose encourages suppliers to apply for a certificate of achievement form, signifying that they are qualified suppliers. One of the primary criteria for gaining certification involves how well the supplier responds to corrective action requests. One of the biggest problems observed is that suppliers often correct problems on individual parts covered by a corrective action form without extending these corrective actions to other part families and applicable parts. Bose has adopted a unique system of marrying just-in-time (JIT) purchasing with global sourcing. Approximately half of the dollar value of Bose’s total purchases are made overseas, with the majority of the sourcing done in Asia. Because foreign sourcing does not support just-in-time deliveries, Bose “had to find a way to blend low inventory with buying from distant sources,” says the director of purchasing and logistics for Bose. Visualizing itself as a customer-driven organization, Bose now uses a sophisticated transportation system—what Bose’s manager of logistics calls “the best EDI system in the country.” Working closely with a national less-than-truckload carrier for the bulk of its domestic freight movements, including shipments arriving at a U.S. port from oversees, Bose implemented an electronic data interchange (EDI) system that does much more than simple tracking. The system operates close to real time and allows two-way communication between every one of the freight handler’s 230 terminals and Bose. Information is updated several times daily and is downloaded automatically, enabling Bose to perform shipping analysis and distribution channel modeling to achieve reliable lowest total cost scenarios. The company can also request removal from a terminal of any shipment that it must expedite with an air shipment. This state-of-the-art system provides a snapshot of what is happening on a daily basis and keeps Bose’s managers on top of everyday occurrences and decisions. Management proactively manages logistics time elements in pursuit of better customer service. The next step is to implement this system with all major suppliers rather than just with transportation suppliers. In the future, Bose plans to automate its entire materials system. Perhaps one of the most unique features of Bose’s procurement and logistics system is the development of JIT II. The basic premise of JIT II is simple: The person who can do the best job of ordering and managing inventory of a particular item is the supplier himself. Bose negotiated with each supplier to provide a full-time employee at the Bose plant who was responsible for ordering, shipping, and receiving materials from that plant, as well as managing on-site inventories of the items. This was done through an EDI connection between Bose’s plant and the supplier’s facility. Collocating suppliers and buyers was so successful that Bose is now implementing it at all plant locations. In fact, many other companies have also begun to implement collocation of suppliers. Assignment Questions The following assignment questions relate to ideas and concepts presented throughout this text. Answer some or all of the questions as directed by your instructor. 1. Discuss how the strategy development process might work at a company like Bose. 2. What should be the relationship between Bose’s supply management strategy and the development of its performance measurement system? 3. Why is purchased quality so important to Bose? 4. Can a just-in-time purchase system operate without total quality from suppliers? 5. Why can some components arrive at the Hillsdale, Michigan, plant with no incoming inspection required? 6. Discuss the reasons why Bose has a certificate of achievement program for identifying qualified suppliers. 7. Bose is moving toward single sourcing many of its purchased part requirements. Discuss why the company might want to do this. Are there any risks to that approach? 8. Discuss some of the difficulties a company like Bose might experience when trying to implement just-in-time purchasing with international suppliers. 9. Why does Bose have to source so much of its purchase requirements from offshore suppliers? 10. What makes the JIT II system at Bose unique? Why would a company pursue this type of system? 11. Why is it necessary to enter into a longer-term contractual arrangement when pursuing arrangements like the one Bose has with its domestic transportation carrier? 12. Why is it important to manage logistics time elements proactively when pursuing higher levels of customer service? 13. What role does information technology play at Bose? 14. What advantages do information technology systems provide to Bose that might not be available to a company that does not have these systems? 15. Why has Bose developed its supplier performance measurement system? 16. Do you think the performance measurement systems at Bose are computerized or manual? Why?
