Abstract

This paper examines issues of rigour and relevance in IS research through an investigation of the validity of case study analysis as a methodology. In order to achieve this it looks at a fundamental issue in the study of information systems: do systems known to deliver accurate, relevant and timely information, actually lead to more effective decision making? The focus is on the applicability of a case study approach to distinguishing IS issues from other organisational factors and on the extent to which such a distinction is valid. The two cases studied are UK National Health Service Trusts. The paper targets the validity of such research into IS issues to establish this differentiation or to refute the existence of factors that are peculiar to IS but are in fact general organisational determinants. This will illustrate some characteristics of IS research and whether they are individual to the field. The context of health service Trusts is one with which there is much familiarity in the IS community and a continual growth of research opportunities and benefits. The research on which this paper is based was designed to establish links between managers' use of information systems and their application of post-suppositional ("What if. ..?") decision making queries
