As experts in automotive market, EBV can help you to recognise the most common terms and abbreviations in the areas of AEC, Functional safety and Telematics:

5 Why


Based on the Ishikawa diagram analysis the 5 Whys is a questions-asking method used to explore the cause/effect relationships underlying a particular problem. Ultimately, the goal of applying the 5 Whys method is todetermine a root cause of a defect or problem.  Ishikawa Diagrams might be known as: Pareto, fishbone diagrams, cause-and-effect diagrams orFishikawa


6 Sigma


refers to a quality improvement and business strategy concept started by Motorola in the United States in 1987.  In statistical terms, 6-Sigma is the abbreviated form of 6 standard deviations from the mean, which mathematically translates to about 2 defects per billion.  Thus, strictly speaking, your process is said to have achieved 6-sigma if it is producing no more than 2 defects per billion parts produced. Nowadays replaced by (or part of) Zero defect tolerance strategies.

IEC61508“This International Standard covers those aspects to be considered when electrical/electronic/programmable electronic (E/E/PE) systems are used to carry out safety functions. A major objective of this standard is to facilitate the development of application sector international standards [ … ] A dual objective of this standard is to enable the development of E/E/PE safety-related systems where application sector international standards do not exist.”  -> applicable for all vehicles esp. those >3,5 t

Delco / GM / Ford –Bussystem (US Standard - new applications addressed with CAN)




Japan Automotive Software Platform Architecture consortium was created by Japanese OEMs to define an open architectural platform, whereby making it easier for all the suppliers and OEMs to develop the next-generation system architecture.




a Japanese term that basically translates to 'continuous improvement' or 'change to become good', is a management concept originated by the Japanese in order to continuously effect incremental changes for the better, involving everybody within the organization from workers to managers. Kaizen is aimed at producing more and more value with less and less wastes (higher efficiency), attaining better working environment, and developing stable processes by standardization.


Media oriented system transport (MOST)

Mistake proofing is a quality management concept developed by a Matsushita manufacturing engineer to prevent human errors from occurring in the production line.Poka yoke (pronounced “poh-kahyoh-kay”) comes from two Japanese words – “yokeru” which means “to avoid”, and “poka” which means “inadvertent errors. The main objective of poke yoke is to achieve zero defects




Level 1 Part Submission Warrant (PSW) only. Level 2 PSW with product samples and other items requested. Level 3 PSW with product samples and complete supporting data. -> Most used format (w/o NDA) Level 4 PSW and other items requested.Level 5 PSW with product samples and complete supporting data available for review at the manufacturer.


Production part approval process (PPAP)


PPAP, 3rd edition, Automotive Industry Action Group (AIAG) is one of the key requirements for the automotive industry. A PPAP document outlines all the manufacturing quality processes that an integrated circuit (IC) manufacturer undertakes for a specific device.




Peripheral Sensor Interface 5 - used forsatelite sensorsf.ex acceleration Sensors in Airbag systems




Part Submission Warrant Beside the testing of the sampled parts the PSW is the basic document for the initial sampling procedure. The PSW is equal to a commitment from customer to release the product ant the intention to use it. Comment: if a customer accepts the sampling with sending back the PSW we (the supplier) needs to confirm every change in the process.(ACN / PCN / PDN must be sent out in time)
