What is PPAP?
PPAP (Production Part Approval Process) is used in the Automotive
Industry supply chain to establish confidence in component suppliers
and their production processes.
The PPAP package is a series of documents which are formally approved
by the supplier and customer.
The form that summarizes this package is called a PSW (Part
Submission Warrant), and it must contain a statistical analysis of
the part data, which is done by PPAP-StatsXPress.
The PPAP package is closely related to the Advanced Product Quality
Planning Process (APQP) used during the design and development of new
vehicles to reduce the risk of unexpected failure.
