Supplier changes can hurt you very bad. I had to evaluate a problem with a GPS assembly that was not able to accomplish a first fix after a change of suppliers of the crystal. On analysis, the replacement device was drifting more in 3 weeks than was permitted over 10 years. The supplier left some acid on the quartz slice. The previous supplier had made a product to spec and the GPS oscillator was within spec. No problem getting a first fix. The manufacturer wanted to just flash the firmware on the GPS to compensate for the drift. That would have been fruitless. The labor to swap the GPS module vs reflash was a wash. They swapped in replacement modules with in-spec crystals and remanufactured the modules with the bad crystal with "in spec" devices. A painful consequence of a supplier change, but resolved to the satisfaction of customer and manufacturer.

Globalists wanking themselves into a frenzy over “policy prescriptions” and “guidance” without a single thought of lining up and imprisoning the thousands of CEOs, MBAs, CFOs, and the like, who shifted all of US manufacturing and FEEDSTOCKS to China.

“Supplier changes can hurt you very bad.”

Yea, people not too close don’t realize the value of a ‘production line’, nor the complexity of it. It’s basically like a well-tuned orchestra. Throw in a replacement member, give him the music, and it will still take a while to get back up to where you were, and that assumes the replacement is as good to start with.
