QS 9000 APQP and PDCA in ISO 9001

Answer:

QS 9000 is old version of the quality system requirements related specifically to the automotive industry and is replaced by TS 16949 and later with IATF 16949. Advanced product quality planning (or APQP) is a framework of procedures and techniques used to develop products in industry, particularly the automotive industry.

PDCA (Plan Do Check Act) cycle is a repetitive four-stage model for continuous improvement in business process management and it is integral part of not only ISO 9001 but many other management system standards, such as IATF 16949, ISO 14001, ISO 27001 and many others.

PDCA and APQP are completely different when it comes to their purpose and nature and they are really hard to compare in any way.
