Management Information Systems
? Terminology Confusion ± MIS = the study of information technology in business settings ± But, MIS is also term to refer to class of systems used to support operational and tactical decisionmaking

A Model for Problem Solving
? Decision Making Phase ± Intelligence gathering ± Design ± Choice ? Implementation ? Monitoring

MIS 175 Spring 2002 Chapter 10

3

Decision Making
? A step in problem solving ? Intelligence gathering ± Definition of problem ± Data gathered on scope ± Constraints identified ? Design phase ± Alternatives identified and assessed ? Choice ± Selection of an alternative
MIS 175 Spring 2002 Chapter 10 4

Structured vs. Unstructured Problems
? Structured problems lend themselves to programmed decisions ± The implication is that a repeatable process can be employed and these can be automated ? Unstructured problems require unprogrammed decisions

MIS 175 Spring 2002 Chapter 10

5

Unstructured Problems
? Can be addressed (or partially addressed) with Decision Support Systems

MIS 175 Spring 2002 Chapter 10

6

Structured Problems
? Can be addressed by an MIS ? Three decision models or techniques ± Optimization
? Find the best solution

± Satisficing
? Find a solution which meets certain criteria

± Heuristics
? Rule-based solution generation
