Advanced Product Quality Planning (APQP) is a structured methodology primarily used in manufacturing industries, particularly within the automotive sector, to ensure that product development processes meet the required quality standards and customer expectations. APQP is rooted in the concept of proactive quality management, encompassing all phases of product design and development, from initial concept to final production. The method was developed by the Automotive Industry Action Group (AIAG) to help suppliers produce high-quality products efficiently, with the goal of minimizing the risks of defects, delays, and cost overruns. In this article, we’ll explore the fundamental aspects of APQP, its phases, tools, benefits, and best practices for successful implementation.
