The Kano Model divides user needs into 4 groups:
Indifference—if you meet this need, user’s feelings are neutral. If you neglect to satisfy this need, user’s feelings are still neutral.
Linear (performance) needs—user’s dissatisfaction/satisfaction is directly proportional to the level this need is met (Note: price is often classified as a linear need)
Basic (must-have) needs—if you satisfy this need, even spectacularly, the user barely notices (neutral); but if you don’t satisfy this need, user is extremely unhappy…miserable, furious, disgusted.
Latent (Excitement) needs—this is the G-spot. These are unexpected features. If you don’t meet this need, the user doesn’t even notice it’s missing. But if you do meet the need, the user is delighted (and writes you chirpy fan mail, pins the product on Pinterest, blogs about it…you’ve struck gold.)
Needs in bold type are more abstract needs, followed by more specific needs that might fall under the more abstract one.
Needs in italics with an exclamation point (!) are what I suspect could be the users’ latent needs.
