                 Typologies of Information Systems
     Information systems studied in this course and their users*:
     •  Transaction Processing system (TPS) – supervisory mgt. (S*), 
        clerks
     •  Management Information System (MIS) – mid-level mgt. (S), 
        supervisory mgt.
     •  Decision Support System (DSS) – executive mgt. (S)
     •  Knowledge Work System (KWS) - professionals
     •  Group Support System (GSS) – professionals, managers
     •  Communication & Social Media Systems – all groups
     •  Enterprise Resource Planning System (ERPS) – clerks, managers
     Typologies show similarities and differences between these systems 
     looking from different angels. 
                                                                         3

                  Typologies of Information Systems:
                     Organizational Function Focus
         • Based on Org. Function: 
            - Production systems (support the core operations in an 
              organization; UofM: Aurora, D2L/UMLearn…)
            - Accounting IS
            - HRIS (human resources)
            - Sales system, Purchasing system, Marketing system …
            - In practice, may be called by brand name (D2L, Concur)
             
         • These systems are usually TPS & MIS
         • Key difference between department-based information 
           systems is in the data coverage (look back at schemas for 
           different business domains)
                                                                        4
                                                                   Bob Travica
                 Typologies of Information Systems:
                                 Time Focus
       •  Based on Time Focus:
        • Present and past focused: 
           – Supporting & recording current operations
           – Reporting on the past business 
           – Shorter range decision making
       •  Future focused                                  Past    Now   Future
           – Planning, predicting
                                                           TPS, MIS     DSS
           – Longer range decision making
                                                                        5

              Typologies of Information Systems (IS): 
                            User Group Focus
     Different systems serve different groups of users.
     Systems have different input data, level of detail, processing capabilities, 
   and
        outputs.
