I have had the oppurtunity to work in the QC and QA department. From what I have seen and experienced as a summer intern, the quality department never had any issues dealing with the other departments or vice versa. Maybe this could have been because both the companies I’ve worked with are very small and therefore communication is stronger and easy. If a signature was missing or certain paperwork had to be completed, it was easy to track the person down since everyone knew each other. Another reason could be that both the companies have had a proper quality system in place and therefore everyone knew the procedure and that is why the company ran smoothly without interruptions from other departments.
