  1. What is MIS? Merle P. MartinCSUSacramento

  2. Agenda • Definition • Complexity Spectrum • MIS Continuum • Development Sequence • Areas and characteristics

  3. Definition Management Information Systems • Management • Focus on decision making • Blunting the technical edge • People-oriented • Output-oriented

  4. Definition • Information • Processed data • Computer or otherwise • Systems • Not just hardware / software • People and procedures

  5. The IT System Hardware/Soft-ware Interface TECHNOLOGY MANAGEMENT COMPUTER USER Connectivity Change Management IT Operations Management Decision Support Database Application Programming Systems Development

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