Partnering Performance Measurement "PPM-AS" to Strengthen Corporate Management of Japanese Automobile Assembly Makers and Suppliers

In recent years, the management issue in the Japanese automobile industry playing a key role in Japanese manufacturing is “worldwide uniform quality and simultaneous production launch,” in response to current globalization. In this corporate management environment, the “key to success in global production” is the reinforcement of product power, or the “simultaneous achievement of QCD.” In order to realize this, it is vital to reinforce Japanese-style partnering, or “Japan Supply Chain Management” between automobile manufacturers and parts suppliers. This is also called the “Japan supply system.” Against this background, this study proposes and verifies the effectiveness of “PPM-AS, or Partnering Performance Measurement for Assembly Makers and Suppliers.” The purpose of “PPM-AS” is to formulate (or visualize) the actual status of “Japanese partnering” between automobile manufacturers and parts suppliers for clearer evaluation and diagnosis. This partnering has been somewhat implicitly carried out in the past, and it is viewed as the basis for deploying “Global Supply Chain Management.”
