Abstract
In order to survive globalization and worldwide quality competition, Japanese manufacturing must work towards the simultaneous achievement of quality, cost, and delivery (QCD) in order to shorten development times, ensure high quality, and lower production costs. Therefore, in this chapter, the author creates the Total Quality Assurance Networking Model (TQA-NM) for the new defect prevention that uses the product quality assurance tools for the new manufacturing management. This model focuses on integrated quality assurance spanning different departments from design to production in automobile manufacturing companies and extending further to part manufacturers. TQA-NM is developed, and its effectiveness is verified at Toyota and its suppliers.
