  4. Types of Decisions in an Organization • Structured decisions • Well-defined standard operating procedure exists • Also called programmable tasks • Can be automated • Semistructured decisions • Not as well-defined by standard operating procedures • Include a structured aspect that benefits from information retrieval, analytical models, and information systems technology

  5. Types of Decisions in an Organization (cont’d.) • Unstructured decisions • Typically one-time decisions • Does not rely on standard operating procedure • Decision maker’s intuition plays the most important role • Information technology offers little support for these decisions • Management support systems (MSSs) • Different types of information systems have been developed to support certain aspects and types of decisions

  6. Phases of the Decision-Making Process • Herbert Simon • Winner of the 1978 Nobel Prize in economics • Defines three phases in the decision-making process: intelligence, design, and choice • Fourth phase, implementation, can be added

  7. Intelligence Phase • Decision maker examines the organization’s environment for conditions that need decisions • Data is collected from a variety of sources and processed • Decision maker can discover ways to approach the problem

  8. The Intelligence Phase (cont’d.) • Three parts • First: determine what the reality is • Second: get a better understanding of the problem by collecting data and information about it • Third: gather data and information needed to define alternatives for solving the problem

  9. Design Phase • Objective • Define criteria for the decision • Generate alternatives for meeting the criteria • Define associations between the criteria and the alternatives • Defining associations between alternatives and criteria involves understanding how each alternative affects the criteria • Information technology does not support this phase of decision making much

  10. Choice Phase • Best and most effective course of action is chosen • From the practical alternatives • Analyze each alternative and its relationship • To the criteria to determine whether it’s feasible • Decision support system (DSS) can be particularly useful in this phase

  11. Implementation Phase • Organization devises a plan for carrying out the alternative selected in the choice phase • Obtains the resources to implement the plan • DSS can do a follow-up assessment on how well a solution is performing

  12. Decision Support Systems • Decision support system (DSS) • Interactive information system • Consisting of hardware, software, data, and models (mathematical and statistical) • Designed to assist decision makers in an organization

  13. Decision Support Systems (cont’d.) • Requirements: • Be interactive • Incorporate the human element as well as hardware and software • Use both internal and external data • Include mathematical and statistical models • Support decision makers at all organizational levels • Emphasize semistructured and unstructured tasks

  14. Components of a Decision Support System • Three major components: • Database • Model base • Includes mathematical and statistical models that enable a DSS to analyze information • User interface • How users access the DSS • DSS engine • Manages and coordinates these major components

  15. Exhibit 12.2 Components of a DSS

  16. DSS Capabilities • What-if analysis • Goal-seeking • Sensitivity analysis • Exception reporting analysis • More capabilities, such as: • Graphical analysis, forecasting, simulation, statistical analysis, and modeling analysis

  17. Roles in the DSS Environment • Roles include: • User, managerial designer, technical designer, and model builder • Users • Most important role because they’re the ones using the DSS • Managerial designer • Defines the management issues in designing and using a DSS

  18. Roles in the DSS Environment (cont’d.) • Technical designer • Focuses on how the DSS is implemented • Model builder • Liaison between users and designers

  19. Costs and Benefits of Decision Support Systems • Benefits of a DSS: • Increase in the number of alternatives examined • Fast response to unexpected situations • Ability to make one-of-a-kind decisions • New insights and learning • Improved communication • Improved control over operations • Cost savings from being able to make better decisions and analyze several scenarios (what-ifs) in a short period

  20. Costs and Benefits of Decision Support Systems (cont’d.) • Better decisions • More effective teamwork • Time savings • Better use of data resources

  21. Executive Information Systems • Branch of DSSs • Interactive information systems that give executives easy access to internal and external data • Typically include: • “Drill-down” features • Digital dashboard • Ease of use • EIS designers should focus on simplicity when developing a user interface

  22. Executive Information Systems (cont’d.) • Require access to both internal and external data • So that executives can spot trends, make forecasts, and conduct different types of analyses • Should also collect data related to an organization’s “critical success factors”

  23. Executive Information Systems (cont’d.) • Digital dashboard • Integrates information from multiple sources and presents it in a unified, understandable format • Often charts and graphs • Many digital dashboards are Web-based

  24. Exhibit 12.3 Digital Dashboard

  25. Reasons for Using EISs • Increase managers’ productivity • Convert information into other formats • Spot trends and report exceptions

  26. Avoiding Failure in Design and Use of EISs • Factors that can lead to a failed EIS: • Corporate culture isn’t ready • Organizational resistance to the project • Project is viewed as unimportant • Management loses interest or isn’t committed • Objectives and information requirements can’t be defined clearly • System doesn’t meet its objectives • System’s objectives aren’t linked to factors critical to the organization’s success • Project’s costs can’t be justified

  27. Avoiding Failure in Design and Use of EISs (cont’d.) • Developing applications takes too much time • System is too complicated • Vendor support has been discontinued • Executives themselves • Nature of executives’ work • Nature of information the EIS provides

  28. EIS Packages and Tools • Generally designed with two or three components: • Administrative module for managing data access • Builder module for developers to configure data mapping and screen sequencing • Runtime module for using the system • Some EIS packages provide a data storage system

  29. EIS Packages and Tools (cont’d.) • Tasks managers perform for which an EIS is useful: • Tracking performance • Flagging exceptions • Ranking • Comparing • Spotting trends • Investigating/exploring

  30. Group Support Systems • Use computer and communication technologies to formulate, process, and implement a decision-making task • Considered a kind of intervention technology that helps overcome the limitations of group interactions • Reduce communication barriers • Introduce order and efficiency into situations that are inherently unsystematic and inefficient

  31. Group Support Systems (cont’d.) • Useful for: • Committees • Review panels • Board meetings • Task forces • Decision-making sessions that require input from several decision makers

  32. Groupware • Assist groups in: • Communicating, collaborating, and coordinating their activities • Intended more for teamwork than for decision support

  33. Groupware (cont’d.) • Some capabilities of groupware include: • Audio and video conferencing • Automated appointment books • Brainstorming • Database access • E-mail • Online chat • Scheduling • To-do lists • Workflow automation

  34. Groupware (cont’d.) • Examples of Web-based GSS tools: • Microsoft Office SharePoint Server and IBM Lotus Domino • Other software used for e-collaboration: • Electronic meeting systems, such as Microsoft LiveMeeting, Metastorm, and IBM FileNet

  35. Electronic Meeting Systems • Enable decision makers in different locations to participate in a group decision-making process • Various types; all have these features: • Real-time computer conferencing • Video teleconferencing • Desktop conferencing

  36. Advantages and Disadvantages of GSSs • Advantages: • Costs as well as stress are reduced due to decreased travel • More time to talk with each other and solve problems • Shyness isn’t as much of an issue in GSS sessions • Increasing collaboration improves the effectiveness of decision makers

  37. Advantages and Disadvantages of GSSs (cont’d.) • Disadvantages: • Lack of the human touch • Unnecessary meetings • Security problems • Costs of GSS implementation are high

  38. Geographic Information Systems • Captures, stores, processes, and displays geographic information • Uses spatial and nonspatial data • Uses three geographic objects: • Points • Lines • Areas

  39. Geographic Information Systems (cont’d.) • Common example of a GIS: • Getting driving directions from Google Maps • User-friendly interface that helps you visualize the route • After you make a decision, you can print driving directions and a map

  40. GIS Applications • Education planning • Urban planning • Government • Insurance • Marketing • Real estate • Transportation and logistics

  41. Guidelines for Designing a Management Support System • Get support from the top • Define objectives and benefits clearly • Identify executives’ information needs • Keep the lines of communication open • Hide the system’s complexity and keep the interface simple • Keep the “look and feel” consistent • Design a flexible system • Make sure response time is fast

  42. Summary • Different types of decisions • Stages of decision making in a typical organization • DSS: • Components, capabilities, key players, and costs and benefits • Executive information systems • Group support systems • Geographic information systems
