Recker, Berente, and Gregor identify three problems with design principles:
Design principles rarely build on existing work (They should be developed over extensive amounts of research (eg review articles), not one-off papers)
Design principles are rarely very surprising or useful (“the UI has to be easy to use”)
They often depend too much on context → indeterminacy
Interesting: even though (to her chagrin) she is the “[Design] Theory” person, Gregor doesn’t always include or look for a design theory in design science research. She said “A theory is just a body of work” in defense of why she doesn’t sometimes include a full Design Theory.
