1 Fundamentals of Information Systems Fourth Edition
Chapter 6 Information and Decision Support Systems

2 Principles and Learning Objectives
Good decision-making and problem-solving skills are the key to developing effective information and decision support systems Define the stages of decision making Discuss the importance of implementation and monitoring in problem solving Fundamentals of Information Systems, Fourth Edition

3 Principles and Learning Objectives (continued)
The management information system (MIS) must provide the right information to the right person in the right format at the right time Explain the uses of MISs and describe their inputs and outputs Discuss information systems in the functional areas of business organizations Fundamentals of Information Systems, Fourth Edition

4 Principles and Learning Objectives (continued)
Decision support systems (DSSs) are used when the problems are unstructured List and discuss important characteristics of DSSs that give them the potential to be effective management support tools Identify and describe the basic components of a DSS Fundamentals of Information Systems, Fourth Edition

5 Principles and Learning Objectives (continued)
Specialized support systems, such as group support systems (GSSs) and executive support systems (ESSs), use the overall approach of a DSS in situations such as group and executive decision making State the goals of a GSS and identify the characteristics that distinguish it from a DSS Identify the fundamental uses of an ESS and list the characteristics of such a system Fundamentals of Information Systems, Fourth Edition

6 Why Learn About Information and Decision Support Systems?
True potential of ISs is to help employees make more informed business decisions These systems can cut costs, increase profits, uncover new opportunities Examples Transportation coordinator can find least expensive way to ship products Loan manager can determine creditworthiness Store managers can better maintain inventory Fundamentals of Information Systems, Fourth Edition

7 Decision Making and Problem Solving: Decision Making as a Component of Problem Solving

40 Components of a Decision Support System (continued)
Figure 6.14: Conceptual Model of a DSS Fundamentals of Information Systems, Fourth Edition

41 The Database Data-driven DSS
Primarily performs qualitative analysis based on the company’s databases Taps into vast stores of information contained in the corporate database, retrieving information on inventory, sales, personnel, production, finance, accounting, and other areas Often uses data mining and business intelligence Fundamentals of Information Systems, Fourth Edition

43 The User Interface or Dialogue Manager
User interface or dialogue manager allows users to interact with the DSS to obtain information Assists with all aspects of communications between the user and the hardware and software that constitute the DSS Fundamentals of Information Systems, Fourth Edition

44 Group Support Systems Group support system (GSS)
Consists of most elements in a DSS, plus software to provide effective support in group decision making Also called group decision support system or computerized collaborative work system Fundamentals of Information Systems, Fourth Edition

46 Characteristics of a GSS That Enhance Decision Making
Special design Procedures, devices, and approaches for creative thinking and effective communication Ease of use Complex systems will seldom be used by groups Flexibility Takes different decision-making styles and preferences into account Decision-making support for different approaches Delphi, brainstorming, group consensus, nominal group Fundamentals of Information Systems, Fourth Edition

47 Characteristics of a GSS That Enhance Decision Making (continued)
Anonymous input Helpful in ranking performance of managers Reduction of negative group behavior Avoids dominance of one member, sidetracking, and groupthink Parallel communication Speeds meeting times and results in better decisions Automated record keeping Provides efficient voting, ranking, future review, and analysis Fundamentals of Information Systems, Fourth Edition

48 GSS Software Often called groupware or workgroup software
Helps with joint work group scheduling, communication, and management Examples: Lotus Notes, Microsoft’s NetMeeting, Microsoft Exchange, IBM’s Workplace, NetDocuments Enterprise, Collabra Share, OpenMind, TeamWare Some transaction processing and enterprise resource planning packages include collaboration software Fundamentals of Information Systems, Fourth Edition

49 GSS Alternatives GSS alternatives include:
Decision room: decision makers in same geographic area; GSS is used occasionally Local area decision network: decision makers in same geographic area; GSS is used frequently Teleconferencing: decision frequency is low; location of group members is distant Wide area decision network: decision frequency is high; location of group members is distant Use virtual workgroups Fundamentals of Information Systems, Fourth Edition
