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. 相似文献

This research adopts the institutional and relational view theories to empirically test the impact of organisational culture (OC) on sustainable supply chain performance (SSCP) and further examines the impact of external integration on their relationship, drawing on a study in the food manufacturing industries in the UK and Greece. Using the mixed method approach, structural equation modelling (SEM) technique was first used to empirically analyse the data from a survey of 315 firms. In addition, insights from 11 interviews from top managers were qualitatively used as the basis to enrich and confirm the findings from the quantitative study. Our findings revealed that in the context of global supply chains only developmental, hierarchical, and group culture components of the competing values framework (CVF) as a model for assessing OC are conducive for achieving a higher SSCP. Although developmental, hierarchical and group cultures are instrumental for SSCP, a strong external integration is still required. Thus, external integration was found to mediate the relationship between the dimensions of OC and SSCP. The results further confirmed a positive relationship between all the dimensions of OC (developmental, group, hierarchical and rational culture) and external integration and a positive impact of external integration on SSCP. This research expands the institutional and relational view theories to examine the effect of OC (using CVF) on SSCP and further reveals the extent of external integration needed in the relationship to enhance SSCP in global supply chains. Supply chain managers are encouraged to adopt integrated competing values, namely, developmental, group, and hierarchical cultures to intensify the external integration in the supply chain to overcome several sustainability challenges and improve SSCP. 相似文献

Today's information technology (IT) organizations are under pressure to meet or improve IT service levels for critical business functions. Various industry standards, such as the IT Infrastructure Library (ITIL) and the Control Objectives for Information and Related Technology (COBIT) standard, have gained wide acceptance as comprehensive methodologies for improving the effectiveness of IT management. The role of IT operations management is subsequently changing from a component orientation (such as networks, systems, storage, database, and applications) to managing business‐oriented, end‐to‐end IT services. This article presents a detailed analysis of available literature in order to identify the most appropriate competencies and necessary skill sets that will be needed by an operation manager for strategic business alignment. 相似文献
