The use of system development methodologies in the development of decision support systems : An interpretive study / J.P.S. EllisEllis, Jacobus Philippus Swart January 2010 (has links)
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.

The development of a hybrid agile project management methodology / Grey, J.Grey, Johannes January 2011 (has links)
The aim of this study is to investigate whether a combination of agile system development methodologies (ASDMs) and project management methodologies (PMMs) can be used to develop a hybrid APMM that will have the ability to deliver information technology (IT) projects successfully in a constantly changing business and project environment.
To achieve this objective, a literature review was conducted on the relatively well–established ASDMs by firstly defining a SDM and an ASDM. Each ASDM and its effectiveness are described, after which ASDMs in general are evaluated by considering their area of application, advantages and disadvantages. A comparison is then done of the seven different ASDMs using the four elements of an SDM (Huisman & Iivari, 2006:32) to emphasise some of the main similarities and differences amongst the different ASDMs. The seven ASDMs investigated in this study are Dynamic System Development Methodology, Scrum, Extreme Programming, Feature Driven
Development, Crystal ASDMs ? Crystal Clear and Crystal Orange in particular, Adaptive Software
Development and Lean Development.
A literature review was also conducted on two structured and relatively well–established PMMs,
PMBOK and PRINCE2, and a relatively new PMM called Agile Project Management. Each PMM is
evaluated by considering their area of application, advantages, disadvantages and integration with
other methodologies, after which a comparison is made of the different PMMs.
The research was conducted by following a mixed methods research plan, which included the
mixed methods research paradigm (combination of the interpretive research paradigm and the
positivistic research paradigm), research methods (design science, case study and survey),
quantitative and qualitative data–collection techniques (interviews and questionnaires), and dataanalysis
techniques (cross–case and statistical).
The reasons that projects fail and critical project success factors were studied and summarised to
form the critical project success criteria, which were used to create the agile project success criteria. The ASDM best practice and PMM best practice frameworks were created by identifying
whether a certain ASDM or PMM would satisfy a specific agile project success factor (APSF) of the
agile project success criteria. The findings of each APSF in the respective frameworks were used
as a foundation to develop a hybrid APMM (ver. 0) that would address the agile project success
criteria. The hybrid APMM (ver. 0) was developed interpretively using design science (research
approach) and constructivism by combining the strengths, addressing the weaknesses and bridging
the gaps identified in the frameworks.
The hybrid APMM (ver. 0) was then evaluated and improved by conducting an interpretive case
study, which entailed interviewing participants from large and small organisations. Once the
qualitative data collected had been analysed using cross–case analysis, the findings were
incorporated in order to create an improved hybrid APMM (ver. 1).
The hybrid APMM (ver. 1) too was evaluated and improved by conducting a survey, which entailed
administering questionnaires to various respondents in order to collect quantitative and qualitative
data. The findings of the statistical analysis of the data were also used to improve the hybrid APMM
(ver. 1), resulting in the final hybrid APMM (ver. 2).
This study demonstrates that a combination of ASDMs and PMMs can be used to develop a hybrid
APMM with the ability to deliver IT projects in a constantly changing project and business
environment. / Thesis (Ph.D. (Computer Science))--North-West University, Potchefstroom Campus, 2012.
