Advanced product quality planning (APQP) is a framework of procedures and techniques used to develop products in industry, particularly in the automotive industry. It differs from Six Sigma in that the goal of Six Sigma is to reduce variation, but has similarities to Design for Six Sigma (DFSS). According to the Automotive Industry Action Group ...
First article inspection. A First Article Inspection (FAI) is a production validation process for verifying that a new or modified production process produces conforming parts that meet the manufacturing specification detailed in technical or engineering drawings. Typically, a supplier performs the FAI and the purchaser reviews the report.
Nadcap was established in 1990 by SAE International. Nadcap's membership consists of "prime contractors" who coordinate with aerospace accredited suppliers to develop industry-wide audit criteria for special processes and products.

It was released in October, 1999, by the Society of Automotive Engineers and the European Association of Aerospace Industries. [1][2] AS9100 replaces the earlier AS9000 and fully incorporates the entirety of the current version of ISO 9001, while ...
DO-178C. DO-178C, Software Considerations in Airborne Systems and Equipment Certification is the primary document by which the certification authorities such as FAA, EASA and Transport Canada approve all commercial software-based aerospace systems. The document is published by RTCA, Incorporated, in a joint effort with EUROC and replaces DO-178B.
ANOVA Gage R&R is an important tool within the Six Sigma methodology, and it is also a requirement for a production part approval process (PPAP) documentation package. [3] Examples of Gage R&R studies can be found in part 1 of Czitrom & Spagon. [4]
Manufacturing readiness level. The manufacturing readiness level (MRL) is a measure to assess the maturity of manufacturing readiness, similar to how technology readiness levels (TRL) are used for technology readiness. They can be used in general industry assessments, [1] or for more specific application in assessing capabilities of possible ...
