This paper uncovers the experiences of automotive suppliers in Thailand, which have implemented web-based application to support vendor managed inventory (VMI). First, we identify enabling factors with greatest influence on the outcomes of web-based application implementation. Data was obtained from seventy tier-1 suppliers of the two biggest automobile assemblers in Thailand. Then, exploratory factor analysis was employed to construct enabling factors and outcomes of this implementation support VMI. The results indicate technology readiness is the most important enabler in implementing web-based application technology to support VMI. It is followed by leadership, and systems integration. In the implementation of such technology, it is important to understand the crucial role that management support and the deployment of relevant technical skills play in the success of such implementation.
