APQP (Advanced Product Quality Planning)

APQP is a very detailed approach to quality planning. This is more a process than a method. APQP describes relatively comprehensively which steps and activities have to be carried out prior to the start of production for a product in order to guarantee a high-quality product for the end customer and thus also to fulfill all customer wishes and requirements. This process is divided into five phases in which the results from the previous phase represent the input for the subsequent phase.


  • Planning
  • Product Development
  • Process Development
  • Product and process validation
  • Series start-up phase

Automotiv- Core Tools

The use of these methods and tools, which are used within the framework of the advanced quality planning / APQP Advanced Product Quality Planning) of new products, promote the quality of the products that are produced in the series process. Thus, efficient and robust process and products are achieved.
