What is MIS? Merle P. Martin CSU Sacramento

Agenda t Definition t Complexity Spectrum t MIS Continuum t Development Sequence t Areas and characteristics

Definition M anagement I nformation S ystems t Management u Focus on decision making u Blunting the technical edge u People-oriented u Output-oriented

Definition t Information u Processed data u Computer or otherwise t Systems u Not just hardware / software u People and procedures

The IT System TECHNOLOGYMANAGEMENT COMPUTERUSER Hardware/Soft- ware Interface Change Management Decision Support Application Programming Systems Development Database IT Operations Management Connectivity

Contrast with Computer Science t Future orientation t Adaptive to change t Satisficing, not optimizing t Business (profit) orientation t Balance between u technology u people

Complexity Spectrum Minor Modifi- cations ComplexityComplexity Major Modifi- cations System Enhance- ments System Replace- ments Maintenance (85%) Development (15%) Systems Analysis (Options to Choose)

MIS Continuum t Data Flow Diagram u Processes (programs) u Data Stores (files) u Data Flows (forms / messages) u External Entities (customers)
