Sort of like those DVD extras we used to have: making of the PbD-model

How can we support designers to create theory-driven Designs for Behaviour Change? The Persuasive by Design-model and its accompanying suite of tools is our answer to that question. In this longread (15 minutes) published on Medium, I introduce the model, offer an insight into its development process and describe how we tried to make this model a useful tool for theory-driven design.
