> Design is not like engineering. In many cases it should? I've seen initial versions of UIs having been created in a certain way because of multiple valid reasons (people that worked on it really put some thoughts into it), those reasons (priorities of fields, differentiation of informations, speed of entering data, overview of the data, ...) were never written anywhere => the next people that worked on it changed that because of any reason and the result was often worse - maybe by having guidelines/explanations associated to the UI (similar to what is done for the app's code) would avoid that.
