I saw -10x: they chose some crazy architecture for something then dug their heels in. The two people who historically got all the work done, both about 5x, decided to quit because of this. So now the work still needed to be done, in the crazy architecture, without the two best engineers, and on top of that time needed to be spent on hiring. Go forward a year and the progress the company made was probably less than it would have in a month before the fancy new architecture was introduced, and the loss of talent. Additionally I've seen managers/HR demotivate a team of 5 so thoroughly that nobody got work done for 2 weeks. That is -5x from a single meeting.
