Essentials of Business Information Systems, 7ELaudon & LaudonLecture Files by Barbara J. EllestadChapter 3 Achieving Competitive Advantage with Information SystemsThe changes that have taken place in computing have affected the business environment in a big way. Over 40 percent of business equipment investments in the last decade have been on technology. Organizations are finding more efficient ways to accomplish tasks via networking, either internal networks or by connecting to external networks. Technology has caused many changes in the way businesses connect to their customers, suppliers, and business partners to achieve a competitive advantage.3.1 Using Information Systems to Achieve Competitive AdvantageGoogle, Amazon, e-Bay–the giants of the Internet. They are successful and make loads of money. They could easily rest on their laurels, kick back, and relax. If they are so successful, why do they keep working so hard to continually introduce new products and services and improve the old ones? Because someone, somewhere, is trying to take their place and become the new giant. These companies must keep the competitive advantage and they are using information systems to do so.Type of Competitive AdvantageThere are four ways companies can create or keep the competitive advantage:1.Barriers to entry that restrict the supply: create supply monopolies.2.Demand control: create and control the switching costs customers wouldexperience if they moved to another supplier.3.Economies of scale: keep operating costs low while expanding sales byincreasing the amount of product or service you provide with the same equipment.4.Process efficiency: improve business processes to make them more efficient andcheaper.Some companies use just one of these to maintain a competitive advantage but most companies will use a combination of them.Porter’s Competitive Forces ModelPorter’s competitive forces model contends that much of the success or failure of a business depends on its ability to respond to its external environment. Figure 3-1 shows four external forces that every business must contend with at one time or another.Figure 3-1: Porter’s Competitive Forces Model.It’s important to understand from this model that a firm’s success is not predicated on how well it does internally. It must also pay attention to:•Traditional competitors: always nipping at your heals with new products and services trying to steal your customers.•New market entrants: not constrained by traditional ways of producing goods and services, they can easily jump into your markets and lure customers away with cheaper or better products and services.•Substitute products and services: customers may be willing to try substitute products and services if they decide your price is too high or the quality of yourproducts and services is too low.•Customers: fickle to say the least, they are now armed with new information resources that make it easier for them to jump to your competitors, new marketentrants, or substitute products.•Suppliers: the number of suppliers used may determine how easy or difficult your business will have in controlling the supply chain. Too few suppliers and you losea lot of control.Information System Strategies for Dealing with Competitive ForcesMany companies have found that effective and efficient information systems allow them to deal with external forces in one of four ways: low-cost leadership, product differentiation, focus on market niche, and strengthen customer and supplier intimacy. Low-Cost LeadershipBy using information systems to lower your operational costs you can lower your prices. That will make it difficult for traditional competitors and new market entrants to match your prices. This strategy works best with commodities such as computers or with household products retailers such as Wal-Mart.Efficient customer response systems provide a company and its suppliers with an integrated view of customers. These systems provide instantaneous information to the company and its suppliers. Every staff member can have access to the information in the system to help reduce costs and prices well below that of the competition. Processes such as supply replenishment are automated between companies and suppliers. When products reach a certain re-order point, the system automatically sends a message to the supplier who can quickly send out new stock. These systems help companies achieve low-cost leadership in their industry.Product DifferentiationA very effective use of strategic information systems is to create products or services that are so different that they create barriers for the competition. Product differentiation is at the heart of Dell Computer Corporation’s success. Its competitors, such as Compaq and IBM, have tried to duplicate Dell’s made-to-order strategic business model but have not been quite as successful.Apple uses product differentiation to help market its iPod and online music system to a broad swath of the population and create barriers that its competitors are having difficulty overcoming.People like to feel that they are unique individuals with their own needs and desires. One of the best strategies for dealing with competitors is to offer customers exactly what they want, when they want it, and how they want it. The Internet provides a new outlet for mass customization by allowing customers to order one-of-a-kind products. For instance, by visiting the Ping Golf Club Web site, an individual can step through a series of pages that will help design golf clubs to fit him/her. The customer answers questions on the site about his/her height, arm length, hand size, and level of play. The site then adviseshim/her on the exact type of club that best fits his/her needs and provides all of the information necessary to order the clubs. Once ordered, Ping can produce the product in a matter of hours and use a shipping partner to deliver the clubs in less than five days. The individual feels special and Ping has gained a new customer.Focus on Market NicheIf an organization is in a fiercely competitive market, it can choose to focus on a very narrow segment of the market rather than a broad general audience. Using data mining techniques a firm can gather very specific information about its customers and create a focused differentiation business strategy to market directly to those consumers. Being able to address the needs and wants of a very small market segment is why companies are so intent on gathering as much consumer information from a variety of sources as they can.Apple Computer uses focused differentiation to help sell its computers to a narrow target market of graphic designers and educators rather than the general population of computer users.Strengthen Customer and Supplier IntimacySupply chain management (SCM) systems increase supplier intimacy while customer relationship management systems increase customer intimacy. SCM systems create immense switching costs between a company and its suppliers because of the investment of hardware and software necessary to make the system successful. Customer relationship management systems allow companies to learn details about customers that give them the competitive advantage over traditional competitors and new market entrants.Implementing these competitive strategies requires precise coordination of people, technology and the organization. A company can pursue one or more of these strategies but cannot isolate any of the three dimensions of an information system. They must all work in concert together to have any hope of success.The Internet’s Impact on Competitive AdvantageTry to think of one industry that has not been touched by the Internet. Its impact on Porter’s Competitive Forces Model is apparent from entertainment to retail to travel to financial services. The Internet allows traditional competitors to introduce new products and services and lure customers away. It provides a low cost avenue for new market entrants. Consumers can easily and quickly find substitute products and services through the Internet. Customers can use information provided on the Internet to create new competition between companies while suppliers can increase their market power. Table 3.3 summarizes the impact the Internet is having on many industries.Not all of the news is bad though. The Internet provides new opportunities for companies to increase their customers and markets while reducing their costs. The companies we first mentioned in this section, Google, Amazon, and e-Bay are continually creating new products and services through the Internet. They are successful because they use information systems to continually improve their strategic competitive forces.The Business Value Chain ModelBe better than the competition. That’s the mantra of most companies that are serious about winning the game. Areas of the organization most affected by leveraging technology are in producing the product, getting it to the stores, and making the customer happy. Remember the WorldWide Candy Corporation from Chapter 2? Think of all the activities that go into getting the Cybernuts candy bar made, from procuring raw materials to actual production. Then consider how the candy bar gets from the factory to the store shelves. And what about all those commercials you see? These are primary activities. Just as important are support activities: human resources, accounting, and finance. These functions support the primary functions of production, shipping, and sales andmarketing. The value chain model shown below will help an organization focus on these activities and determine which are critical to its success.Figure 3-2: The Value Chain Model.By effectively using an information system in a strategic role at any, or preferably all, levels of the organization, a digital firm can provide more value in their products than the competition. If they can’t provide more value, then the strategic information system should help them provide the same value but at a lower price.Benchmarking provides a way for businesses to determine how they stand up against their competitors within the same industry. For instance, if the industry standard in producing golf clubs is ten days, Ping can benchmark their production schedule of five days and determine that they are successful. They can also research the best practices of other golf club manufacturers and decide if they should fine tune their business processes to wring even more resources from the production process.Information to formulate benchmarks and best practices can come from internal sources, other companies within the same industry, external industries, university research units, or the government.Extending the Value Chain: The Value WebMore and more companies are incorporating the Internet in their business strategies through the use of value webs. Ford Motor Company is forming many partnerships and alliances via the Web to offer services and products that otherwise would be too difficult, costly, or time-consuming.“Suppliers are an integral part of our business, and our success isinterdependent with theirs. We rely on more than 2,000 productionsuppliers to provide many of the parts that are assembled into Fordvehicles. Another 9,000 suppliers provide a wide range of nonproductiongoods and services, from production equipment to computers toadvertising.” ( Web site)Ford is using value webs to connect itself, suppliers, and business partners and share best practices so that each participant can improve its business processes. That in turn lowers supply costs for Ford and ensures a certain level of standardization through the manufacturing process. Suppliers can collaborate with each other via the value web to enhance their core competencies and improve the entire supply chain. Sharing information through the value web helps not just Ford but the entire vehicle manufacturing industry.Figure 3-3: The Value Web.Synergies, Core Competencies, and Network-Based StrategiesVery seldom will you find a business that provides all of its own services, supplies, and processes throughout the entire chain. It isn’t practical or efficient to do so. Almost every business relies on partnerships with other companies to produce goods and services. The most successful companies will determine the best synergies, core competencies and network-based strategies to reduce costs, improve products and services, and increase profits.SynergiesAOL has provided dial-up Internet access for consumers and businesses since the early 1990s. In addition to providing Internet access it also creates specific content that is available only to its customers. The last few years has seen a huge increase in the demand for broadband access by customers across the U.S. AOL simply doesn’t have the necessary infrastructure to provide what its customers want. But other telecommunications companies such as BellSouth and Verizon can help AOL answer the demand through their networks. AOL, in synergy with the other companies can now provide the services customers want.“David Scobey, President of BellSouth’s Retail Markets, said, “This newrelationship will make it easier for loyal AOL consumers to get all thebenefits of BellSouth DSL without losing their AOL service. We think thispromotion offers a compelling reason for AOL members to move tobroadband.” ( Web site)In early 2006, two telecommunication industry giants, Verizon and MCI, announced a partnership that will provide new services to large corporations and governments.“Verizon has joined forces with MCI to form Verizon Business, a leadingprovider of advanced communications services for large businesses,government, and international organizations. The vision: To create onetruly seamless, local-to-global IP network. One that works alongside oneof the world’s most reliable wireless networks, providing your businesswith every piece of the solution you need, including the most importantone of all: people.Consumers and small businesses will also benefit from combining MCI’sworld-class Internet backbone with Verizon’s broadband offerings,providing opportunities to advance our broadband services and keep pacewith the increasing demands of the multimedia marketplace.” ()Both companies have superior services. However, it would have been impossiblefor either company to alone provide the new service. Rather than forego the opportunity altogether, they combined their synergies to create new services for customers.Enhancing Core CompetenciesWhy did Ford Motor Company form an alliance with UPS instead of continuing its long-time practice of delivering vehicles to dealers itself? Because Ford wanted to concentrate on its core competency of manufacturing vehicles and let UPS concentrate on its core competency of delivering products.UPSLogistics’Web site says “By shaving four days off the delivery cycleand reengineering the network, Ford is realizing a $1 billion dollarreduction in vehicle inventory and more than $125 million in inventorycarrying-cost reductions on an annualized basis. ‘The savings willcontinue to grow as our precision, Web-enabled system reaches maturityand we surface and eliminate more non-value-added activities,’ saidTaylor. Ford and UPS Logistics Group launched the alliance a year ago toreengineer Ford’s vehicle delivery system amid rising consumer demandfor on-time vehicle delivery. UPS Logistics Group created UPSAutogistics as a business unit to manage the project. ‘With a singlenetwork manager in place to analyze any potential problems before theyoccur, we’ve managed to avoid bottlenecks, reduce the amount of assets inthe supply chain, and cut inventory carrying costs,’ said Tom Kolakowski,manager of Ford North Americ an Vehicle Logistics.”Network-Based StrategiesTechnology doesn’t automatically transform organizations. There is no magic wand companies can wave that will solve all their problems just because they installed the latest information system. People using technology efficiently and effectively, however, can transform organizations. Network technology can enhance communications up and down the organization and from one department to another on the same managerial level. Networks also provide a low-cost, efficient way to connect a firm to its external environment.It’s long been known in the economics field that the economics of manufacturing produces a diminishing return on investment at some point in time. But in network economics the opposite is true. Let’s say you have a small company with 15 employees operating on a client/server network. You’ve already paid for the server that can support 25 employees. When you hire the 16th employee, you won’t have to spend much money, if any, to support the new employee on the network. You’re actually increasing the server’s output without an associated increase in cost.Technology makes virtual organizations more feasible, cheaper, and easier to set up and tear down than before. Let’s say you own a small company in northern Arizona that offers white-water rafting trips through the Grand Canyon. You have a fleet of rafts and 35 full-time employees. Rather than you trying to manage the payroll and benefits program for your employees you could use a company that specializes in payroll, employee benefit programs, and even retirement plans. Intuit, who manufactures Quicken and QuickBooks, also provides an online service for businesses that does all of these things. You access Intuit’s Web site, enter the necessary data, and it takes care of the rest of the processes even down to filing the government tax forms. You can concentrate on your rafting business instead.The Boeing Company, manufacturer of airplanes, uses virtual organizations throughoutits design and manufacturing processes. It contracts with other businesses for certain types of work such as the development of new seat configurations. When the process is up, the outside vendor is released from the job.As more companies outsource work to other vendors, virtual organizations are becoming the norm. Network technologies based on Internet standards provide the infrastructure necessary to make them successful. Companies are no longer tied to suppliers and business partners located in specific geographical areas but can find the best service provider or business partner around the world.3.2 Competing on a Global ScaleThe world just keeps getting smaller and smaller. No company can afford to ignore foreign markets or the impact of foreign competition on the domestic business environment. You have to adapt to the changing faces, literally, of your competition and customers and devise a plan to bring your organization into its view.Globalization OpportunitiesThe Internet allows big companies to act small and small companies to act big. It also provides wider markets for products and services, cheaper labor, and reduced production and shipping costs. A rancher in northern Montana traditionally could only sell his beefto local markets. He can now sell his products to anyone in the world through the Internet. Customers access his Web site, make their selections, and the products are shipped overnight to any geographic location. The rancher has a wider market for his products with reduced costs.Other companies can use networks to outsource some or all of their work to far-flung geographic locations. A small entrepreneur can use a company in Poland to producetrinkets cheaper than anyone in the United States. The entrepreneur can use a global Web site to sell the products anywhere.The Internet totally changes the traditional ideas of where work needs to take place and where the customers are located. Online collaboration systems, which we will investigate in future chapters, allow workers to instantly share documents, graphics, messages, and even phone calls over the Internet at significant costs savings.Global Business and System StrategiesOne globe, one company. Daimler-Chrysler is the perfect example of a transnational corporation. Its Web site describes it as “the first automotive, transportation, and services company with a truly global structure.” Corporate headquarters are “located in Stuttgart, Germany and Auburn Hills, Michigan, U.S.A.” Daimler-Chrysler did business in 200 countries with 441,500 employees at the end of 1998. Much of this was made possible by system strategies that erase the global lines of demarcation.Information systems that allow a business to “time shift” its work can economize on its fixed capital costs. As their work day ends, employees in New York City can shift projects to employees in Seattle. When the Seattle employees leave for the day they can shift the projects over to Tokyo-based employees. Tokyo can move the project on to Frankfurt, Germany who will continue the work. As so it goes around the clock. Companies can produce information-based products and services almost 24/7 using these kinds of strategies.3.3 Competing on Quality and DesignWho wants to eat a candy bar that tastes horrible, drips all over your hands and clothes, and costs way more than it should? WorldWide Candy Corporation from Chapter 2 avoids those pitfalls better than the competition because it uses information systems to enhance the quality of the company and the product. The customer knows that Cybernuts is far superior to any other candy bar in taste, and it’s not that expensive. The customer doesn’t really focus on the fact that chocolate isn’t melting all over her hands. That’s an intriguing aspect of keeping the customer happy when you think about it. The customer doesn’t consider the quality of a product until it isn’t there. Then it may be too late for the producer to win back the customer.What Is Quality?Total quality management, making quality control everyone’s responsibility, relies onan excellent information system to supply workers and management with the data necessary to improve products and drive down costs. The lack of good, useful information may not be apparent until the organization can’t figure out what it’s doing wrong, or doing right. Data from all the types of information systems we’ve discussed can be fed into quality management programs and make it easier to develop and improve products that blow away the competition.Six Sigma is another initiative companies use to spot problems and correct them before they are too deeply embedded in the company’s processes. It just stands to reason that the longer a flaw is allowed to fester in the system, the more problems it may cause. And the more problems, the higher the costs. If you can identify the defects early on and eliminate them, you can achieve more efficient production at lower costs. That’s the premise behind Six Sigma.Neither of these initiatives should be viewed as one time events but rather as continuing processes.How Information Systems Improve QualityHere are some ways companies can use information systems to achieve total quality management:•Simplify processes by using information to determine what the processes are in the first place•Identify benchmark targets•Gather, process, and store customer feedback in information systems that are available company-wide•Reduce cycle time by providing information earlier in the process•Redesign the process or redesign the product by using information about the process•Improve production processes by using available information from internal and external sourcesComputer-aided design software programs can help a business achieve superior quality by incorporating the ideas above into its work processes. For instance, Ping can use CAD software to design new golf clubs and identify benchmarks used in the production process. The engineers can use customer feedback in the design process to determine what type of clubs sell the best.3.4 Competing on Business ProcessesWe often refer to the three dimensions of an information system: technology, the organization, and people. Nowhere is coordination among the three more important than in business process reengineering.Business Process ReengineeringVery few processes in business are as efficient as they can possibly be. It’s a fact of life. The idea behind successful BPR is to find improvements or even new opportunities. For instance, Federal Express and UPS both have online package tracking systems. That simple process was never economically feasible before the Internet. They had to reengineer their business processes to incorporate this new paradigm shift.In order to make BPR successful, you must first redesign the process, then apply computing power to the new processes. If problems existed in the process before the new system was installed and those problems aren’t resolved, the new system could actually make them worse.New information system software is giving businesses the methodology to more easily redesign their processes. Work flow management offers the opportunity to streamline procedures for companies whose primary business is oriented toward paperwork. Instead of 10 people handling a single bank loan application, you can install software that will speed up the process, allow several people to work on the document at the same time, and decrease the total number of people who handle it. Or, you can migrate the application process to the Web and make it even more efficient and customer-friendly. Wells Fargo Bank allows customers to complete an online application and receive a preliminary approval or disapproval within minutes. Wells Fargo’s computer system is connected to the credit reporting agencies’ computers for quick access of customer credit data. If customers have questions about the application or the types of loans available, they can initiate an instant messaging session with a bank employee and get all their questions answered on the spot. Once the application has been submitted, the customer can check the progress of it online. Once the loan is approved, the money is allocated to the customer through an online account. Wells Fargo processes more bank loans faster and more efficiently. The customer is happier with less effort. And all of this can take place 24/7.Steps in Effective ReengineeringBPR attempts fail 70 percent of the time. That’s an astonishing figure when you think about it. What if your car failed to start 70 percent of the time? Some of the reasons for the high failure rate are lack of planning, management’s inability to fully comprehend the enormity and complexity of the effort, and the fact that BPR usually takes much longer than expected.What can organizations, their managers, and workers do to help make BPR a success? It may be helpful to make a diagram of how your processes work now and then envision how they will work after they are redesigned. Figure 3-5 in the text shows an example of how mortgage processing was redesigned using BPR techniques. Try just a few processes to get your feet wet and then expand it to other units or processes within the organization. Document how much your current processes cost. You’ll be able to measure costs savings (or costs increases) better if you have a baseline for comparison.。

第二章商务活动中的管理信息系统§2.3 供应链管理企业供应链的通畅程度决定了这个企业的经营效益。
从订货到销售的过程,一般要采取供应链管理( Supply Chain Management,SCM)方式来控制,包括决定最优库存数量、最佳存货地点、订货计划、配送和运输的方式和自动补货系统等。
也就是对整个供应链系统进行计划、协调、操作、控制和优化的各种活动和过程,其目标是要将正确的产品(顾客所需的产品在正确的时间、按照正确的数量、正确的质量和正确的状态送到正确的地点——即“6R”,并使总成本最小。
§2.3.1 IT支持供应链管理传统的供应链体系是“推动式”的,即制造商生产什么,批发商就推销什么,商店也就卖什么,顾客少有选择的机会和余地。
这种供应链有三个明显的弱点,即:缺乏灵活性、运转周期长、经营成本高,中间批发商的增多必然会提高商品的价格,增加商店的进货成本。
电子商务供应链“以顾客需求为中心”,采用“拉动式”的经营方式,以消费需求刺激,促进和拉动商品供给。
它表现出下面的几个特点:①周转环节少,供应链条短。
由于供、产、销直接见面,商品流转的中间环节大大减少,提高了商品的流转速度。
②灵活性强。
例如商业收款机( POS)不仅是收银机,通过它还可以得到很多的资料及分配情况,使供应链变得更为灵活。
③交易成本低。
由于提高了商品信息的流通速度,减少了商品流通的中间环节,因此整个交易的成本大大降低,无论对于卖方还是对于买方都非常有利。
电子商务供应链管理的主要内容包括:①物流管理:即材料和产品的移动和存储策略的管理。
材料和产品是从供应商通过公司分配系统向零售店和客户运动的。
②实物分配管理:通过计划和调整,控制货物的实际运动。
③分配需求计划:物流主管(成配送主管)制订计划的过程涉及仓库、码头、运输的容量和发货管理。
④实物库存管理:决定库存的水平和重新进货的频率,这取决于经营水平和服务水平。
⑤仓库管理:包括存货地点,产品存放,挑选,接收,分配的管理,以及这些过程的质量监督。
为什么要用管理信息系统?实现卓越经营,信息系统可以帮助企业改善效率,提高生产率。
例子:沃尔玛是世界上最有效率的百货零售商,因为它使用信息系统将所有门店和供应商连接起来。
以更低的成本来运营推出新产品、服务和商业模式信息系统可以帮助企业不断进行产品和服务以及商业模式方面的创新。
苹果公司的成功不仅在于不断进行产品创新服务创新商业模式的创新与顾客和供应商建立更好的关系东方文化跟踪顾客的偏好,提供个性化服务; JCPenney则用信息系统构建跨国供应链零库存。
