Second-Party Quality Auditing in the Automotive Industry: In-depth Methodology Analysis

  • Today automotive producers operate on a global market with very strong competition and vast variety of customers, each with their own preferences. Under these conditions automotive companies need to provide products of excellent quality in order to stay in business. However, managing quality in the automotive production is a particularly demanding task due to the fact that automotive Original Equipment Manufacturers (OEM) have some of the most intricate production networks which exist. They are involved in only about 20% to 40% of the actual production process and the trend is that in the future this share will keep on shrinking. Therefore OEMs should make sure that they cooperate only with reliable and quality capable business partners. Supplier auditing is a very important quality management tool, which is used to assess the capability of a particular supplier to deliver products of high quality and therefore its suitability as a business partner. Quality auditing is employed before awarding contracts and during the series production to assess the quality risks down the supply chain. This work studies the ability of supplier quality auditing in the automotive industry to provide reliable process capability evaluations. The case study presented here was carried out in cooperation with Volkswagen AG and evaluates the effectiveness of the supplier auditing process at the German automotive manufacturer with respect to the challenges on the global automotive market. This paper employs a research approach for assessment of the quality auditing process, which draws similarities to sampling - an important measurement method in the field of Electrical Engineering. The discussion points out important aspects for the technical implementation of the quality audit in the automotive industry as well as critical points regarding the information management of audit evaluation records. Even though the focus of this work is on the automotive industry, the analytical approach and the statistical methods used here can be used to assess the effectiveness of supplier quality auditing also in other industry sectors.
