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

2 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.

3 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.

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

5 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.

6 Fundamentals of Information Systems, Second Edition 6 Decision Making and Problem Solving

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

8 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

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