Organizational and Interorganizational Determinants of EDI Diffusion and Organizational Performance: A Causal Model

Abstract Electronic data interchange (EDI), a specific form of interorganizational systems, has the potential to significantly influence business operations and the exchange of business documents in a number of industries and to provide substantive tangible and intangible benefits to the participating firms. However, successful implementation and diffusion of these systems innovations requires the cooperation and commitment of all participating member firms. A number of interorganizational as well as internal, organization-specific factors can influence both the extent to which EDI is diffused and used and the level of subsequent benefits that accrue to the firms. Research from sociopolitical process framework in marketing, organizational theory, innovation theory, use of information technology for competitive advantage, and information systems (IS) implementation was used to identify 3 interorganizational variables (customer support, customer expertise, competitive pressure) and 4 organizational variables (internal support, EDI's benefits potential, EDI compatibility, resource intensity). In this study, we develop a multidimensional measure for EDI diffusion to capture both external integration and internal integration. We then examine the influence of these 7 variables on the extent to which EDI adopter firms pursue diffusion and whether more diffusion leads to superior organizational-level outcomes. Two senior executives (the chief executive officer and a senior manager responsible for the IS function or EDI) from 83 firms in the motor carrier industry participated in a field survey. The results from a structural equation model (SEM), developed using LISREL, provide quite a strong support for the hypothesized relations. All 4 organizational variables and 2 of the 3 interorganizational variables (customer support and competitive pressure) influence EDI diffusion. The results also indicate that external integration dimension of diffusion enables adopter firms to achieve improved operational and market-oriented performance, whereas internal integration contributes only to operational performance.
