The use of systems development methodologies in web-based application development in South Africa

Abstract

This study investigated the use of systems development methodologies in Web-based application development in South Africa. Web-based systems differ from traditional information systems by integrating different media for knowledge representation and utilizing hypertext functionality. By doing this, Web-based systems not only support creation, integration, analysis, and distribution but also storage and transfer of knowledge of business transactions within a structured information system. There are numerous methodologies available to develop Web-based systems. In this study five of these methodologies were discussed. The methodologies include Web IS Development Methodology (WISOM), Internet Commerce Development Methodology (ICOM), Web Engineering, Extreme Programming and the Relationship Management Methodology (RMM). In this study a qualitative research approach was followed. Case studies were done on three different organizations in the South African marketplace. Semi-structured interviews were used for data collection at each organization. The interviews were transcribed, and the data were analysed using content analysis and cross-case analysis. One of the main goals of this research was to determine "how" system development methodologies are used in practice to develop Web-based systems, and to what extent it is used. The research pointed out that those organizations who participated in this study in South Africa mainly use in-house developed methodologies to develop Web-based systems, and that these organizations adhere strictly to their methodology. The main reasons organizations choose to use methodologies are that methodologies aid in the delivery of a better quality Web-based system, and also act as a good project management mechanism within the organization.
