Designers should not be afraid of being criticized and afraid to make mistakes. Any new design will have errors or flaws. As long as they are discovered during EVT/DVT or even PVT trial production and corrected in time before mass production, they are fine. I have seen many engineers insist on their own opinions during trial production or attribute the errors to production line assembly problems or incoming material quality problems. If they are not corrected in time and wait until PVT to correct them, the losses will become increasingly greater! I once encountered a case where a junior supervisor resigned after DVT. The engineers under his supervision did not deal with this defect in a timely manner. The PM was also inexperienced and accepted the engineers' countermeasures. At that time, I was stationed at Huawei and After the PVT test, the defect rate was still high. Resisting the pressure of everyone pushing for mass production, I halted the production schedule and requested two weeks to develop five experimental plans and instruct the engineers to track and document the root cause before resuming production. This kind of situation has happened to me in my 14 years of R&D experience, but we must focus on uncovering the root cause rather than just seeing the minor issues on the surface. Obvious mistakes must be avoided so that we can focus on addressing the fundamental issues. Innovation companies' R&D work allows for trial and error within a controlled range, which is the driving force for growth. My strengths are attention to detail and the ability to quickly spot problems. My weaknesses are overthinking and a tendency to be too obsessed with perfection, which I've been working on over the years. Having children these past few years, I've become more accustomed to using patience, encouragement, and creative communication. The above is my working experience. Thank you for taking the time to review it.
