Success is complicated. If you are a big company success often means getting promotions and raises. At a small startup success might mean getting the company acquired. When success depends on pleasing your boss or peers it really has more to do with their check list than any list like you created. Different people value different things. When success depends on getting a company acquired then sometimes having all your bases covered is very helpful.
