The selection and use of system development methodologies

Abstract

Selection of system development methodologies (SDMs) are driven from characteristics of the organisation using the SDM, and the project to which the SDM is applied by individuals working on it. No figure is available for the number of SDMs, but the need exists to select the correct SDM to use. Although previous selection models only focus on the project, the organisation and individual were identified as also having an influence, thus the selection should be made on organisational level, project level, and individual level. This research aimed at identifying characteristics of the organisation, project, and individual levels that can guide the selection of an SDM. This led to the construction of a conceptual model for this research. Using the conceptual model and empirical research, a survey was used as the research method. Statistical analysis was used to identify which characteristics of the organisation, project and individual have an influence on the selection and use of an SDM. It was determined that the various characteristics of each level influence which SDM should be used, either directly or indirectly. The influence these characteristics have on the selection is presented in a theoretical framework based on the conceptual model constructed. This addresses the need for the organisation, project and individual to be involved in the selection of an SDM to use. This research will impact future research about contingency, and the selection of SDMs that “fit” the organisation, project, and the individual. This theoretical framework could be expanded to propose the SDM to use, refining the influence of the identified characteristics on the decision.
