Comparison of Information System Development Methodologies

摘要

This research critically evaluated a select sampling of current information systems development methodologies. The research had two primary objectives. The first was to enhance the manager's understanding of information systems and design methodologies. The second was to provide a tool to assist managers in deliberately choosing which methodology best fits their own specific needs. Two sets of attributes were selected as the basis for an evaluative framework to compare methodologies. One set was chosen based on an information systems development life-cycle model. The intent was to specifically compare the utility of the methodologies for development throughout the complete range of information systems development. Another set of attributes was derived from factors that contribute to the institutionalization of the change represented by the information system in the organization. Each of the selected methodologies was then compared in relation to its degree of coverage of the attributes in the framework. A matrix format was used to present the relative coverage of the different methodologies within the bounds of the framework.
