- #5: Developed by Human Factors It’s a toolkit of principles designed to help Motivate, Enable and Constrain user behaviour. Strong focus on interaction and en- couraging “Will do” actions from usersBroadly compliments usability, but there are a few important exceptions. It’s a toolkit of concepts. Not a rule book.
