Hello everyone! Need help with selecting terms for translation. The situation is as follows: A new production process is being developed. First, this process is tested on lab-scale equipment to see if it goes ok. (It may be full-scale equipment in a workshop too.) If any bugs are identified, they are removed and trials are repeated to refine the process before going to larger scale production. In Russia we call the above actions "otrabotka tehnologii", which could be translated with more or less matching the original as "process refining". So, here is the question: Is there a term in the U.S. that could cover the above situation? Please, share your experience. Thank you.
