The importance of a safe, reliable, cost-effective, high-quality, integral, and nimble supply chain cannot be overstated. Equally critical are the supply chain processes (e.g., strategic, procurement, quality assurance, technical, regulatory) that ensure these requirements are met. By extension, then, the supply chain professional is of paramount importance as a creator, driver, and full participant in these business-critical activities. ASQ's Certified Supplier Quality Professional (CSQP) certification provides valuable credentials to quality professionals in the growing field of supplier quality engineering. Due to globalization of the supply chain, supplier quality engineers are becoming more important in a broad spectrum of industries, including manufacturing and service industries. The purpose of this handbook is to assist individuals taking the Certified Supplier Quality Professional examination and provide a reference for the practitioner. Throughout this handbook, several examples are provided based upon the collective experience and knowledge of the authors and editor. However, these examples are not explicitly specified in regulations, leaving decisions to the company, as well as the burden of justifying practices using sound scientific principles that provide the context of the rationale.
