Due to our project management system and comprehensive approach, we develop and launch the required product volumes in a short time, reducing costs for our partners. We work according to APQP and PPAP methodologies.
APQP (Advanced Product Quality Planning)
APQP is a methodology for preparing (including planning and developing) processes to produce a product that meets all customer requirements and expectations. The methodology emphasizes the prevention of potential errors, using tools such as Failure Mode and Effects Analysis (FMEA) and the Control Plan.
The APQP project consists of six phases, each of which includes a set of measures to ensure target quality:
- Planning and definition of a management plan;
- Product design and development;
- Design and process development;
- Product and process approval;
- Feedback, evaluation, and corrective actions;
- Management plan methodology.
PPAP (Production Part Approval Process)
The PPAP process is designed to demonstrate that the supplier has developed its design and manufacturing process to meet customer requirements, minimizing the risk of failure through the effective use of APQP.
PPAP is a series of documents that require formal certification/sign-off by the supplier and approval/sign-off by the customer.
