One funny thing was that our team of 4 hardware folks built something in a year and a team at a competitor took more than twice as long with a *much* larger team to build something similar. I wouldn't recommend our methodology, but it wasn't as important as other factors.
Another funny thing is that a lot of high-level promotions went out in our competitor's team; the incredible effort they put in was prima facie evidence that the problem must be very hard and we have no real way to measure problem complexity, but that's a topic for another thread
