PERSPECTIVES ON THE PERFORMANCE OF SUPPLY CHAIN SYSTEMS: THE EFFECTS OF ATTITUDE AND ASSIMILATION

The introduction of information systems into industry to enhance operational efficiency is a common business strategy. Introducing such information systems should be expected to enhance employee satisfaction if the systems work as expected. Based on previous studies of supply chain management (SCM) and using institution theory, and technology use and acceptance models, this study applies the lens of attitude and assimilation to explore employee behavior toward using SCM systems after implementation, as well as how employees' attitude and assimilation impact on the performance of the supply chain. Collecting data from employees in the relevant departments from selected companies through a survey and applying SEM in the analysis, the study finds that the employee's perceived ease of use, perceived usefulness, and the subjective norm (Theory of Reasoned Action) have a positive impact on their attitudes toward their use of the SCM systems. Furthermore, it was found that top management's positive beliefs and participation also have a positive impact on assimilation and SCM performance. Finally, it was found that attitudes toward the use of SCM systems impact upon information performance but not in other outcomes of SCM operations. Implications for research and practice are raised. This study contributes to the body of knowledge by adding to our understanding of the relationships among users' attitude, assimilation, and business performance at the post-adoption stage within the context of SCM systems.
