I was never formally educated in that field but I just try to make something I would want to use. Bragging: I've been complimented by a Xerox exec "this looks better than our software" There is a lot more theory and practices than I will ever understand. But if you are not an expert, just ask yourself if you would want to use it. Not as a developer, but some random user.
