Renault SA and Nissan Motor Co. Ltd. executives said their joint purchasing operation has changed production processes and saved money.
Because of combined purchasing, Renault adopted Nissan's quality management system and Nissan is following Renault's use of modules in vehicle design, said Jean-Baptiste Duzan.
Duzan is managing director of the Renault-Nissan purchasing organization.
"Nissan has had a tremendous impact on our quality approach," Duzan said. "The Nissan quality system is very successful. It has been very well received by suppliers because it is positive and they can use it to seek help."
Renault's quality already has improved, Duzan said.
"We have not reached the Nissan level, but we are on the curve," he added. "When we say common suppliers, it means common standards. We can only choose the supplier together if we agree on everything - including quality."
