Just-in-time purchasing: an empirical study of operational practices, supplier development and performance

This paper examines the role of supplier development in establishing and managing efficient buyer-supplier operational links. The paper develops and assesses a measurement instrument for "operational" and "supplier development" just-in-time purchasing practices, followed by an examination of the relationships between the two sets, and an investigation into whether the use of "operational" and "supplier development" practices has a bearing on higher plant performance. A plant-level survey was carried out on a sample of electronics and machinery plants. The study empirically: - documents the close connection between the buyer-supplier operational link and the buyer's practices for supplier development; - demonstrates that recourse to supplier development programs and their nature depend on the kind of vendor-vendee operational connection; - test whether different plant performance outcomes result from the implementing of different "operational" and "supplier development" practices. It demonstrates that better-performing plants exhibit more advanced design and logistic links with sources, more formalised vendor-rating and ranking procedures, greater use of organisational devices for supplier-organisational integration and place greater importance on supplier assistance and training.
