A Contingent analysis of the relationshiop between IS implementation strategies and IS success

摘要

This study suggests that based on the planned change theory the behavioral management strategies of information system (IS) implementation are divided into 3 kinds of strategies—the empirical/rational, the normative/re-educative, and the power/ coercive ones. And the integrative research framework of contingent relationships between these strategies and IS success is reasoned theoretically and hypothesized. This research model includes 10 contingency variables. Five of them relate to the characteristics of the environment under which IS is implemented and the remaining five relate to the characteristics of the task replaced or supported by an IS. An empirical analysis of 109 IS implementation projects in 57 Korean Business firms suggests the existence of three generic behavioral management strategies of IS implementation and significant contingent relationships between these strategies and IS success. That is, three generic strategies proved to be identified empirically through common factor analysis. To test the contingent relationships statistically, multiple regression analyses, in which the independent variables were the three strategies and the dependent variable was IS success, were performed for the subsamples bifurcated according to the median values of each contingency variable.
