Some antecedent factors that shape actors' adoption of enterprise systems

This paper proposes a conceptual model based on technology-organization-environment (T-O-E) and institutional frameworks and examines how the traditional and isomorphic factors explain adoption of enterprise systems (ES) by service small and medium enterprise (SMEs) in Nigeria. The model extends the T-O-E framework by integrating environmental typology with institutional changes in order to recognize homologous behavior in the social systems. Logistic regression and Wald's statistics were used to analyze the data from field survey questionnaire administered to a purposive and snow-ball sample of 262 executives. The results show that adoption of ES is significantly influenced by organizational, technological and isomorphic factors though normative and mimetic isomorphism had negative coefficients; a unit increase in the complexity of the two attracts less analogous modeling and mimicry or vice versa. The technical, economic and legitimated elements are critical adoption determinants; thus, managers make informed decisions that improve competitive advantage when they understand the institutional homogeneity that drives less efficiency in the social structure.
