About 10 years ago, Daimler launched the zero error program. Employees should try to achieve O – errors in development, production, quality (e.g. no calls back) and commercial and technical transactions. M.E. has not yet quite succeeded. I myself am on a good path in the private sector. My sales at eBay under rinnsaal have not received a negative / red rating until today. I am on the right track. a little pride. Greetings – Dieter.
