I agree with @srg36 about the nuances when it comes to quality control. Quality assurance process and quality control processes are crucial for any company/organization. In fact, it’s so important that it should be paid attention carefully and fully invested so that it function as efficiently as possible. For example: hiring the best people knowning what they are doing, good commucation plan, streamline process…(I summarized these points in a different post). What I have seen is that people from quality control and quality assuarance and people from R&D are often not synchronized in a process, even about the same topic. Maybe, people from quality control and quality assuarance can be introduced the R&D a bit more and their work should be also constantly checked for reduncy and effectiveness.
