Design for impulse, Robert Fabricant
Robert makes the distinction between outputs, outcomes, and impacts:
“1. Outputs: the specific products & services that you will be distributing.
2. Outcomes: the immediate changes in user behavior that result from interacting with these products and services.
3. Impacts: the value / overall effect of this behavior in addressing your goals.”
He also points out that ““Behavior change is at the core of good interaction design.”
