PERCEIVED IMPORTANCE OF INFORMATION-SYSTEM SUCCESS FACTORS - A META ANALYSIS OF GROUP-DIFFERENCES

Factors influencing the success or failure of an information system (I S) have been discussed frequently in the literature. This study identi fies several additional factors and proposes that the existing ones be classified into eight different dimensions. These encompass, not only the system aspect, but also the human aspect of IS success (ISS). The study further uses data from past ISS studies and also those collecte d from a field survey to analyze the differences in the perceived impo rtance of ISS factors between four groups of subjects from North Ameri ca, namely, the user staff, the IS staff, and the managers of the two groups. It reveals that the rank orders of ISS factors between IS staf f and IS managers and between user staff and user managers are not sig nificantly different. However, the rank orders between IS personnel an d user personnel are significantly different. Based on these, the top and the least important ISS factors are identified. The findings have several implications for IS management practice. (C) 1997 Elsevier Sci ence B.V.
