Harvard Business Review writes that behavior is changed in five steps:
1. Make it understood.
2. Make it easy.
3. Make it desirable.
4. Make it rewarding.
5. Make it a habit.
Example of the great benefits of changing behavior:
Handwashing promotion is an extremely cost-effective intervention: a $3.35 investment in hand washing brings the same health benefits as an $11 investment in latrine construction, a $200 investment in household water supply and an investment of thousands of dollars in immunization.
Consider the implications for UX.
1. Make it understood.
Make it clear how one is to navigate.
2. Make it easy.
Make it easy to move through the app.
3. Make it desirable.
How is a user rewarded by the app for interaction? What do they get out of it? Does the game provide escape? Does the utility work?
4. Make it rewarding.
Is there tactile, aural or visual feedback?
5. Make it a habit.
Is the experience consistent throughout? Will the user want to use this app again?
