What is MIS? Merle P. MartinCSUSacramento
Agenda • Definition • Complexity Spectrum • MIS Continuum • Development Sequence • Areas and characteristics
Definition Management Information Systems • Management • Focus on decision making • Blunting the technical edge • People-oriented • Output-oriented
Definition • Information • Processed data • Computer or otherwise • Systems • Not just hardware / software • People and procedures
The IT System Hardware/Soft-ware Interface TECHNOLOGY MANAGEMENT COMPUTER USER Connectivity Change Management IT Operations Management Decision Support Database Application Programming Systems Development
Contrast with Computer Science • Future orientation • Adaptive to change • Satisficing, not optimizing • Business (profit) orientation • Balance between • technology • people
