  1. Types of Information Systems:Ways to Use IT in Organizations MIS 320 Kraig Pencil Summer 2014 PPT Slides by Dr. Craig Tyran

  2. A. Game Plan • Introduction • Basic functions of IS • Types of information systems • TPS … MIS … DSS … ES … • Office automation systems • Functional Area Information Systems • And more ! PPT Slides by Dr. Craig Tyran

  3. B.

  19. F. Decision Support Systems (DSS) • The key Cs: Create and Convey • DSS can come in many forms • Managers often use spreadsheet-based DSS • MIS 320 Excel experiences will be helpful! • Common components of a DSS (see figure) • User interface • Model management • Data management

  20. DSS: Paper Production Planning and Scheduling Models: Product demand forecast Capacity planning/scheduling Paper roll cutting Company Data Base Easy to use interface, Data charts, etc.
