Clearly not screwing up is an important strategy and it is entirely down to Sony that they did not screw up.
I'm not really sure how Nintendo screwed up. Wii U is a good machine for the price (though maybe not for the launch price), the tablet controller works well, they might have been a bit slow to release games but they have a good library of games only 1 year after launch. Perhaps they didn't need a tablet controller and the Wiimotion plus could have seen Nintendo through 2 generations. But I think mostly Nintendo just didn't understand it's Wii audience and that most of them were never going to buy into the generation anyway.
MS did screw up plain and simple, almost in every possible way except they didn't release a console with a high failure rate.
