learning objectives
Learning Objectives
  • Have knowledge of different frameworks for understanding BIS
  • Classify BIS according to type of problem and managerial activity (Gorry and Scott Morton, 1971)
  • Classify BIS according to generic operations (Alter, 1979)
  • Classify BIS according to dominant technology component or driver of the decision support system, type of users, purpose of systems and primary deployment technology (Power, 2002)
  • Have an overall view of how topics are organised for IMS3001

DSS and BIS

No universal definition of DSS

  • DSS are interactive computer-based systems which help decision makers utilize data and models to solve unstructured problems – Gorry and Scott Morton (1971)
  • DSS couple the intellectual resources of individuals with the capabilities of the computer to improve the quality of decisions. It is a computer based support system for management decision makers who deal with semi-structured problems – Keen and Scott Morton (1978)
  • DSS is an umbrella term used to describe any and every computerised system used to support decision making in an organisation

dss and bis1
DSS and BIS

Compared to BIS? Recall from Lecture 1

  • BIS is an information system that provides BI to business decision makers at different levels of organisation (operational, tactical, strategic levels)
  • BIS is an information system that turns selected data, information, and/or knowledge into desired intelligence for business gain (Thierauf, 2001)

dss and bis2
DSS and BIS

Decision support context for BIS

  • Assumes that business intelligence is used by decision makers to support them in their business decision making
  • There should be an element of BI (either as a process, product, or organisational function) if DSS framework is adopted

Decision Support Frameworks

gorry and scott morton s framework for decision support 19711
Gorry and Scott Morton’s framework for Decision Support (1971)

Based on

  • Simon’s (1977) idea that decision making processes fall along a continuum that ranges from highly unstructured to highly structured (left column)
  • Anthony’s (1965) taxonomy of managerial activities: operational control, managerial control and strategic planning (top row)

Decision Support Framework for BIS

We adopt Power’s expanded framework with emphasis on how the system provides Business Intelligence to decision makers

  • Data-driven BIS – information systems that provide BI through access and manipulation of large databases of structured data
  • Model-driven BIS – information systems that provide BI through access and manipulation of models (mathematical, conceptual, etc)
  • Knowledge-driven BIS - information systems that provide BI through access and manipulation of predictive models and/or knowledge bases (containing expert’s domain knowledge)

decision support framework bis
Decision Support Framework BIS
  • Document-driven BIS - information systems that provide BI through access and manipulation of unstructured, semi-structured or well-structured documents
  • Communications-driven and Group BIS - information systems that provide BI through communications, collaboration, negotiations among members of team, group, or organisation structure
  • Hybrid BIS – combination of any two or more of the above types of BIS

summary
Summary
  • Different frameworks for understanding DSS
  • Types of DSS according to type of problem and managerial activity (Gorry and Scott Morton, 1971)
  • Types of DSS according to generic operations (Alter, 1979)
  • Types of DSS according to dominant technology component or driver of the decision support system, type of users, purpose of systems and primary deployment technology (Power, 2002)
  • Types of BIS based on Power’s framework and based on how the system provides BI to decision makers
