Who needs a PPAP?
The Production Part Approval Process (PPAP) is used by OEM’s and other large organisations to minimise the risk that component suppliers are unable to meet their expectations. This is an important part or their risk management strategy and helps to satisfy the ISO 9000 / TS 16949 requirement that:-
The organisation will ensure that purchased product conforms to the specified purchase requirements….and will select suppliers based on their ability to meet the organisations requirements
The Production Part Approval Process used in the automotive industry, requires suppliers to provide their commercial clients customers with evidence that –
- Component suppliers have understood their requirements,
- The product meets the customers requirements
- The production process is capable of consistently producing conforming product
PPAP approval is normally required before component can be used in volume production, and failure to achieve PPAP approval may have serious implications for the supplier and the their customer
How you can achieve PPAP Approval
PPAP is an important part of the product development process, allowing OEM’s to evaluate the components and sub-systems which they receive from suppliers, and establishing confidence in the supplier’s management systems. Although individual vehicle manufacturers have their own customer specific requirements, the Automotive Industry Action Group (IAAG) has developed a common PPAP standard as part of the Advanced Product Quality Planning Process (APQP) – encouraging the use of common terminology and standard forms to document component status.
The PPAP process is designed to demonstrate that component suppliershave developed their design and production process to meet the client’s requirements, As suppliers are expected to use Advanced Product Quality Planning APQP to reduce the risk of failure, requests for part approval may be supported by:-
- Sample Parts
- Documentary evidence from the APQP development process.
- Evidence of satisfactory design and process validation
The evidence may be collated as the project progresses from concept through to production, reducing the administrative burden and overheads associated with the approval process. However, the supplier must demonstrate that they have responded to changing customer requirements, and that records are up to date.
Failure to follow the the APQP development process, or poor record keeping exposed during the PPAP process will undermine confidence in the quality of the components supplied and supplier’s management systems.

The level of risk associated with particular failure modes is determined by considering:-
- The effects the failure will have when it occurs (Severity), and
- The chance that the causes of failure will be present (Occurrence), and
- The ability to detect when the error condition is present (Detection) allowing the effects of failure to be prevented or minimized.
