This article defines and discusses one of these qualitative methods-the case research strategy. Suggestions are provided for researchers who wish to undertake research employing this approach. Criteria for the evaluation of case research are established and several characteristics useful for categorizing the studies are identified. A sample of papers drawn from information systems journals is reviewed. The paper concludes with examples of research areas that are particularly wellsuited to investigation using the case research approach.

The concept of decision support systems that emerged in the seventies offered the promise of computer-based tools that would enable decision makers to develop better and more creative solutions to the problems they face. The realization of this promise depends on the validity of two assumptions: (1) individuals can be helped to be more creative and (2) software, appropriately designed, can provide this help. Evidence from creativity research supports the first assumption. This paper explores the second assumption. A set of guidelines for designing DSS is developed from the creativity literature and two hypotheses involving the use of a DSS developed in accordance with these guidelines are proposed. To test these hypotheses, an experiment involving three groups of auditors from a “big eight” accounting firm was conducted. Each group was asked to respond to two different decision situations. Two groups were given separate versions of a DSS specifically selected because it contained features that were thought to enhance creativity. Another group was given no software. The results of the experiment indicate significant differences in the creativity of the responses generated by the three groups. Possible explanations for these differences are explored.
