Well, in theory you should design to be safe for the worst crews on their worst days. Even if something is designed to be usable by the "average crew", nearly half of your pilots on a given day will be below the level that you designed for. And even the average ones or the best ones can be stressed or startled or sleep deprived or all three.
So either the design has to be - quite literally, fool proof - or the training has to be consistently good.
