DSS has many definitions
Complexity of managerial decision making is increasing
Computer support for managerial decision making
Several MSS technologies including hybrids
 There are no specific rules (convergence is taking a leading role)

Why Decision Support Systems?
 Decision support systems (DSS) can help managers
understand problems in addition to providing solutions
 The objective of decision support systems is to increase the
effectiveness of decision making

Figurehead, performs routine duties of social, ceremonial, or legal nature
Leader, motivates subordinates
Liaison, maintains network of contacts in environment for trading information and services
Monitor, seeks and acquires information to have understanding of organization and its environment

Managers and ICT
 Managers need information and use information and
communication technology to support the decision making

IS and Managerial Decision Making
 Management is a process by which organizational goals are
achieved through the use of resources




Resources = Inputs
Goal attainment = Output
Measuring success is determined through productivity
Productivity = Outputs/Inputs

From TPS to DSS
 Computer applications evolving from TPS and MIS to
proactive applications such as decision support systems
(DSS)
 New modern management tools for decision support could
be reflected in
 Data access
 On-line analytical processing (OLAP)
 Internet/Intranet/Web

From Unstructured to Structured
Simon Taxonomy 1977
 Unstructured problems have no structured phases (often
solved with human intuition)
 Semi-structured problems have some (or some parts with)
structured phases (usually solved with standard solution
procedures and human judgment)
 Structured problems have all structured phases
 Procedures for obtaining the best solution are known
 Objectives are clearly defined
 Management support systems can be useful

Decision Making Phases
Simon Taxonomy 1977
 Intelligence
 Searching for conditions that call for decisions
 Design
 Inventing, developing and analyzing possible courses of action
 Choice
 Selecting a course of action from those available

Since the 1960s
Repetitive in nature
High level of structure
Can abstract, analyze and classify them into prototypes
Solve with quantitative formulas or models

Scientific Approach for
Managerial Decision Making

Define problem
Classify problem
Construct mathematical model
Find and evaluate potential solutions
Choose and recommend a solution
Modeling is transforming the real-world problem into an
appropriate prototype structure

DSS as a Concept
 DSS are interactive computer-based systems, which help
decision makers utilize data and models to solve
unstructured problems (Scott Morton, 1971)
 Decision support systems couple the intellectual resources of
individuals with the capabilities of the computer to improve
the quality of decisions
 DSS are computer-based support system for management
decision makers who deal with semi-structured problems
(Keen and Scott Morton, 1978)
 There is no universally accepted definition of DSS
