Use a defined set of tests along with real world metrics. [1] Ensure your tests match reality as close as possible. Ensure you test for the most important events found in the real world. In the case of crash tests, make sure you test for crashes that often cause death or serious injury. Real world metrics get really tricky and expensive, but when speaking about life and safety, it's probably important enough to measure. It's also very important to be smart about measurement and reporting of events, statistics, and trends. 1. http://lesswrong.com/lw/1ws/the_importance_of_goodharts_law/ http://lesswrong.com/lw/1ws/the_importance_of_goodharts_law/
