  1. Information and Decision Support Systems Fundamentals of Information Systems, Second Edition

  2. Principles and Learning Objectives • Good decision-making and problem-solving skills are the key to developing effective information and decision support systems. Fundamentals of Information Systems, Second Edition

  3. Principles and Learning Objectives • The management information system (MIS) must provide the right information to the right person in the right fashion at the right time. Fundamentals of Information Systems, Second Edition

  4. Principles and Learning Objectives • Decision support systems (DSSs) are used when the problems are more unstructured. Fundamentals of Information Systems, Second Edition

  5. Principles and Learning Objectives • Specialized support systems, such as group decision support systems (GDSSs) and executive support systems (ESSs), use the overall approach of a DSS in situations such as group and executive decision making. Fundamentals of Information Systems, Second Edition

  6. Decision Making and ProblemSolving Fundamentals of Information Systems, Second Edition

  7. How Decision Making Relates to Problem Solving Fundamentals of Information Systems, Second Edition

  8. Programmed versus Nonprogrammed Decisions • Programmed decisions • Easy to computerize • Nonprogrammed decisions • Rules and relationships not defined • Problem is not routine • Not easily quantifiable Fundamentals of Information Systems, Second Edition

  9. Problem Solving Approaches • Optimization: find the best solution • Satisficing: find a good solution • Heuristics: rules of thumb Fundamentals of Information Systems, Second Edition
