5. Evaluate



This fifth phase is about testing the best Nudge(s) ideas you have pre-selected in the previous step and watch their efficiency. The input to this Evaluate phase are your Nudge ideas, that you may have prototyped.

Then you are going to test them, enhance them and reduce the risks (if any) surrounding those ideas by adapting them to qualify for the next step’s scale up! If you do it right, you’ll stay confident about the project and, as an output, will be prepared for implementation.
