Start of series production

The primary goal of the series start-up phase is to gradually convert a new product from the laboratory-like conditions of development into a stable, manufacturable series product. This phase begins as soon as all product components have been successfully integrated into the prototype construction and ends with the ability to produce in the desired quality and quantity.
