Advanced product quality planning (APQP) is a framework of procedures and techniques used to develop products in industry, particularly in the automotive industry. It differs from Design For Six Sigma in that the goal of DFSS is to reduce variation. According to the Automotive Industry Action Group (AIAG), the purpose of APQP is "to produce a product quality plan which will support development of a product or service that will satisfy the customer." It is a product development process employed by General Motors, Ford, Chrysler, and their suppliers. History Advanced product quality planning is a process developed in the late 1980s by a commission of experts who gathered around the 'Big Three' of the US automobile industry: Ford, GM, and Chrysler. Representatives from the three automotive original equipment manufacturers (OEMs) and the Automotive Division of American Society for Quality Control (ASQC) created the Supplier Quality Requirement Task Force for developing a common understanding on topics of mutual interest within the automotive industry. This commission worked five years to analyze the then-current automotive development and production status in the US, Europe, and especially in Japan. At the time, the Japanese automotive companies were successful in the US market. APQP is utilized by US automakers and some of their affiliates. Tier 1 suppliers are typically required to follow APQP procedures, techniques, and are also typically required to be audited and registered to IATF 16949. This methodology is also being used in other manufacturing sectors. The Automotive Industry Action Group (AIAG) is a non-profit association of automotive companies founded in 1982. The basis for the process control plan is described in AIAG's APQP manual These include: failure mode and effects analysis (FMEA) manual statistical process control (SPC) manual measurement systems analysis (MSA) manual production part approval process (PPAP) manual Main content of APQP APQP serves as a guide in the development process and also a standard way to share results between suppliers and automotive companies. APQP specifies three phases: Development, Industrialization, and Product Launch. Through these phases, 23 main topics will be monitored. These topics must be completed before the production is started. They include the following aspects: design robustness, design testing, and specification compliance, production process design, quality inspection standards, process capability, production capacity, product packaging, product testing, and operator training plan. APQP focuses on: Up-front quality planning Determining if customers are satisfied by evaluating the output and supporting continual improvement APQP
