Advanced Product Quality Planning (APQP) is a structured approach to product and process development that aims to ensure suppliers understand customer requirements and are able to meet them. It involves 5 phases - planning and defining the program, product design and development, process design and development, product and process validation, and feedback and assessment. The key goals of APQP are up-front quality planning, satisfying the customer, and supporting continual improvement. Common roadblocks to effective APQP implementation include a lack of management commitment, unclear responsibilities, and insufficient resources or knowledge.
