The increasing complexity of automotive products and the need to control quality, time and costs make Product Quality Planning a strategic activity for automotive companies. In this context, Advanced Product Quality Planning (APQP) provides a structured methodology to prevent risks, reduce late changes and ensure robust product and process development. This thesis analyses APQP as a preventive quality framework, with reference to IATF 16949 and AIAG-VDA APQP 3rd Edition, highlighting the role of its phases, deliverables and risk-oriented tools throughout the product lifecycle. The thesis originates from the internship carried out at BCS Automotive Interface Solutions, where a new global APQP standard composed of 43 deliverables was developed to harmonize quality practices across different plants.
