The Kano Model
Interaction Design Foundation Free Beginner
Kano gives you a vocabulary for why exciting features can mislead you: delighters add satisfaction, but missing basics (reliability, honouring what you promised) actively create anger. It shows that a broken basic hurts more than a shiny delighter helps. That is the model behind treating reliability as non negotiable and exciting as optional.
- Basic expectations, when broken, cause outsized anger
- Exciting delighters add satisfaction but never cover a broken basic
- Reliability is a must have, not a nice to have
