Public ISBD [article]  in Journal of operations management > Vol. 14 N°4 (Novembre 1996) . - pp. 333–343 Titre : An exploration of supplier selection practices across the supply chain Type de document : texte imprimé Auteurs : Thomas Y. Choi, Auteur ; Janet L. Hartley, Auteur Année de publication : 2007 Article en page(s) : pp. 333–343 Note générale : Génie Industriel Langues : Anglais (eng) Mots-clés : Out-sourcing  Supplier  chain  Supplier-selection  practices Résumé : The US auto industry has undergone tremendous changes during the past decade. Companies have increased their level of out-sourcing and are relying more heavily on their supply chain as a source of their competitive advantage. Thus, determining which suppliers to include in the supplier chain has become a key strategic consideration. However, previous studies of supplier selection have not considered a company's position in the supply chain. In this paper, we compare supplier-selection practices based on a survey of companies at different levels in the auto industry. Our findings rebut the common thinking that indirect suppliers who are more involved in commodity purchasing emphasize initial price and de-emphasize relational considerations. We learned that selecting suppliers based on the potential for a cooperative, long-term relationship is just as important to direct and indirect suppliers as it is to the auto assemblers. We also learned that price is one of the least important selection items, regardless of position on the supply chain. Further, contrary to the existing understanding that quality and delivery are separate constructs, they formed a single construct in our study. To summarize the empirical results, no differences among the auto assemblers, direct suppliers, and indirect suppliers were found for the importance placed on consistency (quality and delivery), reliability, relationship, flexibility, price, and service. Statistically significant differences were found between the auto assemblers and indirect suppliers on the importance placed on technological capability and financial issues.

ISO 9000/1994, ISO 9001/2000 and TQM / Micaela Martínez-Costa in Journal of operations management, Vol. 27 N° 6 (Décembre 2009) 

Public ISBD [article]  in Journal of operations management > Vol. 27 N° 6 (Décembre 2009) . - pp. 495–511 Titre : ISO 9000/1994, ISO 9001/2000 and TQM : The performance debate revisited Type de document : texte imprimé Auteurs : Micaela Martínez-Costa, Auteur ; Thomas Y. Choi, Auteur ; Jose A. Martínez, Auteur Année de publication : 2010 Article en page(s) : pp. 495–511 Note générale : Génie Industriel Langues : Anglais (eng) Mots-clés : Quality  management  ISO  9000  TQM  Postal  survey Résumé : The debate about the impact of ISO 9000/1994 on performance has been waging since its inception. While there is a general agreement regarding the positive impact of TQM on performance, there has been less agreement among the academics about the impact of ISO 9000/1994. Perhaps in response to such debate, the new ISO 9001/2000 has appeared purporting to be more in line with the TQM philosophy. As of now, how this 2000 version actually affects performance is yet to be explored. In this study, we compare the implementation of ISO 9000/1994 and ISO 9001/2000 as representing two different efforts to implement quality management practices. We evaluate its impact on company performance with a sample of 713 Spanish industrial companies. We also examine if the 2000 version of ISO is taking us closer to the implementation of TQM. Further, we depart from the past studies methodologically by considering performance as a formative construct rather than a reflective construct. Based on the mean and covariance structural (MACS) analyses, we conclude that ISO 9001/2000 certified companies do not perform noticeably better than ISO 9000/1994 or non-certified companies. However, we find that ISO 9001/2000 certified companies apply TQM at a higher level than ISO 9000/1994 certified companies, but whether they actually perform better is less clear.

Supplier–supplier relationships in buyer–supplier–supplier triads: Implications for supplier performance / Zhaohui Wu in Journal of operations management, Vol. 28 N° 2 (Mars 2010) 

Public ISBD [article]  in Journal of operations management > Vol. 28 N° 2 (Mars 2010) . - pp. 115–123 Titre : Supplier–supplier relationships in buyer–supplier–supplier triads: Implications for supplier performance Type de document : texte imprimé Auteurs : Zhaohui Wu, Auteur ; Thomas Y. Choi, Auteur ; M. Johnny Rungtusanatham, Auteur Année de publication : 2011 Article en page(s) : pp. 115–123 Note générale : Génie Industriel Langues : Anglais (eng) Mots-clés : Supplier–supplier  relationships  Triads  Co-opetition  Supplier  performance Résumé : A growing number of studies and evidence from industries suggest that, besides managing the relationship with its suppliers, a buyer needs to proactively manage the relationships between those suppliers. In a buyer–supplier–supplier relationship triad, the buyer, as the contracting entity, influences the suppliers’ behaviors and the relationship between them. By considering the relationships in such a triad, we are able to gain a richer and more realistic perspective of buyer–supplier relationships. In this study, our goal is to examine supplier–supplier relationships in buyer–supplier–supplier triads, focusing on how such relationships impact the supplier performance. We frame the supplier–supplier relationship as co-opetition—one in which competing suppliers work together to meet the buyer's requirements. We investigate the role of the buyer on such relationships, and how the buyer and co-opetitive supplier–supplier relationships affect supplier performance. We find mixed empirical support for our hypotheses. However, we are able to demonstrate the dynamics of supplier–supplier co-opetition in the buyer–supplier–supplier triad. We point out the need for further studies in this area.
