If I can’t immediately decide on a good name, I like to take a single word (or occasionally as many as three) that describes it, and take the initial (or initials) and use that as a code name. That way I know I’ve got to change it, and avoid the risk of retaining a bad name because of inertia. One project I have going at present is code named “B”. Some previous examples have been “ABC”, “C” and “V”.
