Investigating Information Systems Failures

Companies have invested large amounts of money on information systems development. Unfortunately, not all information systems developments are successful. An extensive body of research stream has focused on software reliability studies for the past two decades and many software reliability growth models have been developed for the estimation of software reliability and the number of errors embedded in the software. Comparatively few studies relate software structure to information systems failures. In this study the relationships among variables business requirements change, software complexity, program size and the error rate in each phase of software development life cycle are tested and interpretations of the hypotheses testing are provided.
