The purpose of this paper is to understand how lean production (LP) practices are associated with operational performance in the Brazilian automotive supply chain. A survey was carried out to identify the effect of 11 lean practices on five operational performance metrics. The sample comprised 64 companies of the Brazilian automotive supply chain. Results suggest that Brazilian companies are experiencing reduction of Lead time due to the implementation of total productive maintenance practices; and reducing inventory based on the adoption of just-in-time practices. Nevertheless, there appears to be a significant gap in the way these companies are implementing LP practices, which may hinder the achievement of better operational performance results. The survey was limited to companies from Brazil and, therefore, its findings might not be expanded to other companies or sectors. The results also provide a better understanding regarding LP practices and their individual effect on performance metrics.
