The validation of development reaches its peak in the manufacturing of a functional prototype. This allows for the first software and hardware tests to be conducted. Based on these tests, critical adjustments to the layout and components are often made to ensure the functionality of the electronic assembly and to compensate for potential deviations.

Production follows the same process as for zero-series or mass production. The work preparation team reviews the data sets and clarifies production details. The procurement team sources components, PCBs, and necessary tools. If needed, alternative component options are discussed with the customer to find the most suitable solution.
