Identifying a problem, choosing an algorithm to solve it, and implementing that algorithm. I'd say 1 is the hardest for computers and 2 and 3 are the hardest for humans. There's a cliff in artificial intelligence that people have been saying is just on the horizon for decades. Eventually they'll be right.
