对是做assignment的！case study：RFID on Wal-Mart Business Model.

CASESTUDY: Wal-Mart Grapples with RFID

Wal-Mart was always known for itsultra-efficient distributor systems that kept operating costs much lower thanits rivals. But now its costs are climbing faster than those of competitorssuch as Costco and Target, and this retail giant is looking for a newbreakthrough to maintain its price advantage. It appears to be pinning itshopes on RFID. Wal-Mart management believes that implementing this technologywill help the company wring new efficiencies out of itsretail stores, warehouses, and suppliers.

Wal-Mart has been RFID-enabling its retailstores and distribution centre, while ordering its top suppliers to use RFIDtags on all products they ship. The objective is toreduce out-of-stock items by tracking item locations more precisely as itemsmove from the receiving dock to store shelves. Wal-Mart is selling RFIDas a technology that will eventually save everyonemoney.

Wal-Mart wants RFID readersinstalled at store receiving docks to record the arrival of pallets and casesof goods shipped with RFID tags. The RFID reader reads the tags a second timejust as the cases are brought onto the sales floor from back-room storageareas. Software uses sales data from Wal-Mart’s point-of-sale systems and RFIDdata about the number of cases brought out the sales floor to figure out whichitems will soon be depleted and automatically generates a list of items to pickin the warehouse to replenish store shelves before they run out. Thisinformation helps Wal-Mart reduce out-of-stock items, increase sales, and furthershrink its costs.

Wal-Mart is sharing all its RFID data withsuppliers through its Retail Link Extranet. The RFIDdata improve inventory management because suppliers know exactly where theirgoods are located within 30 minutes of the goods’ movement from one part of aWal-Mart store to another. Sales improve because the system allows Wal-Mart toalways have products in stock.

Despite these benefits, the RFIDimplementations have not progressed exactly as planned. Wal-Mart initiallyhoped to have up to 12 of its 130 distribution centres using RFID by January2006. As of October 2007, only five have implemented the technology, along with600 of Wal-Mart’s 60,000 suppliers and 600 Wal-Mart retail stores.

Costs of RFID tags, readers, and supportingsystems are a barrier. In addition to buying large quantities of RFID tags, thesuppliers have to purchase additional hardware – RFID readers, transponders,antennas, and software to track and analyze the data.

Suppliers also have to pay fornew software programs to integrate the RFIDsoftware with their inventory and manufacturing systems and to change some oftheir business processes. Meeting Wal-Mart’s RFID requirements might run over$20 million for a large supplier.

RFID tags still cost 10 to 15 cents apieceand must be attached by hand at the warehouse. These tags, particularly thelatest expensive types, may not perform properly when they are near certainliquids, metals, or porous objects. To ensure accuracy and proper performance,suppliers may have to use more expensive tags. RFID-tagging a case of goodsmight easily cost a supplier that shipped 15 million cases and pallets toWal-Mart each year would be spending an extra $6 million in tag costs.

Some Wal-Mart suppliers report benefits fromRFID. Pacific Coast Producers, which sells Wal-Mart$400 million worth of packaged and canned fruit each year, started RFID-tagginga handful of products to meet Wal-Mart’s requirements in 2005. It integrated the RFID data with other corporate systems.The company reports it is able to see from the RFID-generated data which storesare not doing a good job of keeping its products on shelves so that it can workwith Wal-Mart to improve those stores’ performance. Pacific Coast plans toRFID-tag more items for Wal-Mart within the next few years.

Other suppliers off the record saythey do not expect any return from their RFID investments for years, if at all.They have refrained from publicly criticizing Wal-Mart, which buys $260 billionproducts annually. For some Wal-Mart suppliers, achieving a return on theirRFID investment is less important than keeping the giant retailer happy. AsHoward Stockdale, chief information officer of Beaver Street Fishes put it, “Doyou want to risk the business by not being in the game?”

Wal-Mart CIO Rollin Ford insists that RFIDtechnology is producing solid results in the company’s supply chain operations,including a 30 percent improvement in out-of-stockrates in stores where RFID has been deployed. The company expects toRFID-enable 400 more retail stores in 2007.

Tasks:
As an Information System (IS) consultant, you arerequired to write a report to explain and analyst the RFID technology relatedto Wal-Mart about the company’s IS strategy based on the case study



a)
Howis RFID technology related to Wal-Mart’s business model? How does it benefitsuppliers?

b)
Explainwhy Wal-Mart suppliers had trouble implementing RFID system? Relate this topeople, organization, and technological factors.

c)
Recommendunder what conditions would you adopt RFID so that it would be more favourablefor the supplier



d)
Giveyour opinion on whether Wal-Mart should require all its suppliers to use RFID.




e)
Describesome RFID applications that might pose a threat to privacy. What informationdoes RFID enable them to track?




f)
Howdot his application threaten personal privacy? How serious is this threat?

G) Shouldthese RFID applications be deployed? Why or why not? Justify your answer byprovide a report presentation and conclusion. Your report presentation must beclear and understandable. Also the conclusion must summarise your whole ideabeing presented in the report in a constructive and convincing manner.

这是英文subject 的吧。。
看你的critical thinking.
用常识回答就能了。

fritlizt

老实讲。 我知道。 不过不想回答你。
要问问题还要--〉“我先要知道谁知道RFID“？？？？？
你是老板？如果我是ibiteyou99，直接不想reply.
问题你不明白在那里你也不讲。
就把整个assignment贴在这里．谁这样得空帮你做assignment？

加上，　这篇文章不需要对ｒｆｉｄ很专业的认知就可以明白。
如果你讲你完全不明白，我还真的不信。
我还真想封帖。　不过这样做不太好。
等有心人来帮楼主吧。

RFID 这里不是没有人会。。。
我还设计RFID 读卡机给汽车保安（Immobilizer）用呢。。
论坛是交流的平台， 但也是有限制的。

我不想这里变成100%问功课， 等答案的地方，而且还是全部英文， 没有看到你提出自己的看法， 而且你的问题和电子技术无关， 只是RFID 和商业应用的课题。

那么， 不可以讨论吗？可以啊， 但我希望网友可以自己先做做看， 把你的答案先写出（中文）， 然后大家才讨论，（参考版规）。  同样的问题， 如果你发在国外的英文论坛， 我相信是直接删帖的。

现在我把帖封了， 作为反面教材， 希望网友们不要再犯。
如果你有意见， 请PM 我。
