The world we live in today demands systems that make our lives easier and help us
make the right choices on time. There exists a growing need for quality products that
help us in our day to day activities. Easy-to-use computer-based decision support
systems apply all available and applicable data with the correct model, knowledge
and skill of decision makers to support the user to choose the best solution. It is
therefore important to develop decision support systems correctly to be of value to
the user. Looking at other information system developments, the author tries to
suggest ways to develop decision support systems. System development
methodologies are investigated to determine if they are able to address the
development of the very important decision support system components. Five
methodologies were discussed and researched for their theoretical suitability to
address the development of decision support systems. The author performed
qualitative research using case studies and semi-structured interviews to assess the
use or non-use of system development methodologies in the development of
decision support systems in a South African context. Content and cross-case
analyses were used to achieve results that are discussed to broaden the knowledge
on the development of decision support systems. The author provides some
explanations to why system development methodologies were not used in the
development of the case studies. This research not only contributes to the academic
body of knowledge about using system development methodologies in the
development of decision support systems, but could also be useful to developers
embarking on a new decision support system development. / Thesis (MSc (Computer Science))--North-West University, Potchefstroom Campus, 2011.
