The Fogg Behavior Model

The Fogg Behavior Model shows that three elements must converge at the same moment for a behavior to occur: Motivation, Ability, and Trigger. When a behavior does not occur, at least one of those three elements is missing. 

Using my Behavior Model (FBM) as a guide, designers can identify what stops people from performing behaviors that designers seek. For example, if users are not performing a target behavior, such as rating hotels on a travel web site, the FBM helps designers see what psychological element is lacking.

I have used this as an approach to identifying problems in the design of mobile software during my time in China. It was a great way to frame the activity.
