Knowledge that Transforms

The results from a five-part Delphi survey of chief IS executives and corporate general managers indicate the most critical information systems management issues and consensus on their importance. The research project is the second in a series of such studies conducted by the Society for Information Management and the MIS Research Center at the University of Minnesota. The research confirmed the expected in some areas and revealed surprises in other areas. While strategic planning continued to top all issues in importance, many changes have occurred since 1983. Three new issues have joined the top ten issues in importance. Also, the rank order of several issues in the top ten has shifted. Survey results are discussed in terms of the differing views of IS executives and corporate general managers. A review of how these views have changed over time is also presented. A number of conclusions are drawn about managing information systems and about the changing nature of the IS executive’s job.

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 well-suited to investigation using the case research approach.

A field study of middle- and upper-level managers was undertaken to explain managers’ selection of communication media. The findings indicate that media vary in their capacity to convey information cues. Managers prefer rich media for ambiguous communications and less rich media for unequivocal communications. The data suggest that high performing managers are more sensitive to the relationship between message ambiguity and media richness than low performing managers. Implications for managers’ use of information systems and electronic media are discussed.

The concept of consumer ethnocentrism is introduced and a corresponding measure, the CETSCALE, is formulated and validated. Four separate studies provide support for the CETSCALE's reliability and convergent and discriminant validity. A series of nomological validity tests show consumer ethnocentrism to be moderately predictive of theoretically related constructs.

Disconfirmation models of customer satisfaction employing three alternative standards of performance were compared by using causal modeling. Pre- and post-measures were obtained from subjects in three different use situations. The disconfirmation paradigm is supported. The analysis suggests that best brand norm and product norm are additional standards used for evaluating focal brand performance.

The diffusion rate of a first purchase diffusion model is interpreted as the intensity function of a counting process. Parameter estimation procedures are considered and some generalizations of the basic model are discussed.
