I heard Derek Featherstone give a very insightful presentation at An Event Apart in Washington DC where he talked about a minimally viable interaction. This is an interesting way of thinking because it moves away from the focus on the product or service, to the use of the product or service.
Someone needs to do something. What are the minimum number of steps needed to allow them do it? What is the minimum amount of content for each step? If they need to fill out a form what is the minimum number of fields in that form?
