“…IT Usefulness and Ease of Use ment Corporation (Good, et al, 1986) measure user perceptions to guide the development of new information technologies and products; industry publications often report user surveys (e.g., Greenberg, 1984;Rushinek and Rushinek, 1986); several methodologies for software selection call for subjective user inputs (e.g., Goslar, 1986;Klein and Beck, 1987); and contemporary design principles emphasize measuring user reactions throughout the entire design process (Anderson and Olson 1985;Gould and Lewis, 1985;Johansen and Baker, 1984;Mantei and Teorey, 1988;Norman, 1983;Shneiderman, 1987). Despite the widespread use of subjective measures in practice, little attention is paid to the quality of the measures used or how well they correlate with usage behavior.…”

“…There is a considerable body of literature that has addressed the issue of IS/IT appraisal (see for example, Lucas and Moore, 1976;King and Schrems, 1978;Ginzberg, 1979;Hamilton and Chervancy, 1981;Chandler, 1982;Klein and Beck, 1987;Hawgood and Land, 1988;Hirschheim and Smithson, 1988;Parker et al, 1989;Willcocks, 1994), and there appears to be general agreement that appraisal of IS/IT investments is a task which most organizations feel they have a responsibility to perform (Carlson, 1974). However, despite the existence of this wealth of literature, even as at 1997 the IS community appears to be no nearer a solution to many of the problems associated with IS/IT appraisal.…”

This paper explores the techniques used by organizations to appraise Information Systems (IS)/Information Technology (IT) investments, and concentrates, in particular, on techniques of capital investment appraisal. We draw on relevant studies reported in both the accounting and ® nance, and the IS literature, which have addressed their usage. Where possible comparisons are drawn between both sets of literatures. The results of a survey that speci® cally examined IS/IT investment appraisal practices of a sample of UK companies is also presented. Among the issues discussed include the extent to which capital investment appraisal techniques are used to appraisal investments, the importance of the techniques used and the problems attendant on the decision making process.

The authors report the findings of a survey of hospital managers on the utilization of various project selection and evaluation methodologies. The focus of the analysis was the empirical relationship between a portfolio of project evaluation(1) methods actually utilized for a given project and several measures of perceived project success. The analysis revealed that cost-benefit analysis and top management support were the two project evaluation methods used most often by the hospital managers. The authors' empirical assessment provides evidence that top management support is associated with overall project success.
