6 Business Processes and Operations Roles of IS in BusinessSupportStrategiesfor CompetitiveAdvantageSupportBusiness DecisionMakingInformation Technology is increasingly important in the competitive marketplace. Managers need all the help they can get. Information systems perform three vital roles in business:Support Business Operations. From accounting to tracking customers' orders, information systems provide management with support in day-to-day business operations. As quick response becomes more important, the ability of information systems to gather and integrate information across business functions is become crucial.Teaching Tip: For example, the ability to match a change in product items sales with as a result of a new marketing campaign to the inventory and ordering system, can help keep items in high demand in stock.Support Business Decision Making. Just as information systems can combine information to help run the business better, the same information can help managers identify trends and to evaluate the outcome of previous decisions. IS helps managers make better, quicker, and more informed decisions.Support Strategies for Competitive Advantage. Information systems designed around the strategic objectives of the company help create competitive advantages in the marketplace.Teaching Tip: For example, Wal-Mart stores can provide lower prices in part due to the lower costs incurred by their state-of-the art computerized inventory, tracking, and distribution system.SupportBusiness Processes and Operations

9 Types of Information Systems Support ofManagerialDecision MakingSupport ofBusinessOperationsOperationsSupportSystemsManagementSupportSystemsInformation Systems can be classified by the type of support they provide an organization.Operations support systems process data generated by and used in business operations. They produce a variety of information products for internal and external use. Operations support systems do not emphasize producing the specific information products that can best be used by managers. Further processing by management information systems is usually required. The role of a business firm’s operations support systems is to:1. Effectively process business transactions (TPS)2. Control industrial processes3. Support team and workgroup collaborationManagement support systems assist managers in decision making. Providing information and support for decision making by all types of managers and business professionals is a complex task. Conceptually, several major types of information systems support a variety of decision-making responsibilities.1. Management information systems - provide information in the form of reports and displays to managers and many business professionals.2. Decision support systems - give direct computer support to managers during the decision-making process.3. Executive information systems - provide critical information from a wide variety of internal and external sources in easy-to-use displays to executives and managers.TransactionProcessingSystemsProcessControlSystemsEnterpriseCollaborationSystemsManagementInformationSystemsDecisionSupportSystemsExecutiveInformationSystemsProcessingBusinessTransactionsControlof IndustrialProcessesTeam andWorkgroupCollaborationPrespecifiedReportingfor ManagersInteractiveDecisionSupportInformationTailored forExecutives

13 Developing IS Solutions InvestigateAnalyzeMaintainDesignEmphasis on the steps in the traditional information systems development cycle is based upon the stages in the systems approach to problem solving: (More details in Chapters 10-12)Systems Investigation. This stage may begin with a formal information systems planning process to help sort out choices from many opportunities. Typically, due to the expense associated with information systems development this stage includes a cost/benefit analysis as part of a feasibility study. This stage is covered in more detail on the following slide.Systems Analysis. This stage includes an analysis of the information needs of end users, the organizational environment, and any system currently used to develop the functional requirements of a new system.Systems Design. This stage develops specifications for the hardware, software, people, and data resources of the system. The information products the system is expected to produce are also designated.Systems Implementation. Here the organization develops or acquires the hardware and software needed to implement the system design. Testing of the system and training of people to operate and use the system are also part of this stage. Finally, the organization converts to the new system.Systems Maintenance. In this stage, management uses a postimplementation review process to monitor, evaluate, and modify the system as needed.Implement

From the end user perspective, it is necessary to understand the fundamentals of systems theory:System. A system is a group of interrelated components working together toward a common goal by accepting inputs and producing outputs in an organized transformation process.Systems have the following three basic interacting functions:(Give examples of each)Input. Input involves capturing and assembling elements that enter the system to be processed.Processing. Processing involves the transformation of input into output.Output. Output is the end result of the transformation process. Output involves transferring elements that have been produced by a transformation process to their ultimate destination.Identify:External Constituencies.Feedback Systems.Managerial Control.EconomicResourcesBusinessResourcesGoods &ServicesSuppliersStockholdersInputProcessingOutputFinancial InstitutionsLabor Unions

These include all sets of information processing instructions. Software resources include:System Software. This controls the computer.Application Software. These are for a specific end user task, such as word-processing.Procedures. These are the operating instructions for the people who use the IS.Data Resources. Data is both the raw material of and among the most valuable organizational resources in the IS. Data can be in alphanumeric, text, image and/or audio form. Data are typically organized into either Databases - which hold processed and organized data; or Knowledge bases - which hold knowledge in a variety of forms such as facts and rules of inference about a given subject.Data:Data is the plural of datum, though data commonly represents both singular and plural forms.Data are raw facts or observations, typically about physical phenomena or business transactions.Data should be viewed as raw material resources that are processed into finished information products.Data are usually subjected to a value-added process (data processing or information processing) whereIts form is aggregated, manipulated, and organizedIts content is analyzed and evaluatedIt is placed in a proper context for a human userInformation:Information can be defined as data that have been converted into a meaningful and useful context for specific end users.Information should be viewed as processed data which has been placed in a context that gives it value for specific end users.
