Designer-buyer-supplier interface: Theory versus practice

The paper focuses on facilitating an interface and collaboration among designer, buyer, and supplier at three planning horizons: strategic, tactical, and operational with respect to supplier relations. To accomplish this interface, nine propositions for all areas of interface at three levels of planning are presented. These included: (1) long-term strategic alliances,(2) supplier R&D investment and financial strength, (3) confidential relationships, (4) reduction in the number of suppliers, (5) information sharing, (6) supplier plant visitation, (7) supplier selection, evaluation, and certification, (8) supplier training/meetings, and (9) the inspection and receiving policy. Then, each proposition is evaluated in practice for a company and the extent of difference from theory to practice is identified. The results indicate that the company performed well for three propositions (4), (7), and (9), while it performed very poorly for six propositions of(1), (2), (3), (5), (6), and (8). These results indicate that the company performed poorly in the strategic aspects of supplier relationships. The company performed marginally well in the tactical aspects of supplier relationships. The company performed well in the operational aspect of supplier relationships. Finally, the conclusions, assessment, and future research directions are presented. (C) 2000 Elsevier Science B.V.
