  1. “If you have a choice of two things and can’t

    decide, take both”
 Gregory Corso
  2. “Improving each attribute of a companies product or service will

    not necessarily lead to greater customer satisfaction” Noriaki Kano
  3. Threshold Features (must have) • Basics required for the product

    to compete • Improving performance or volume will have little impact on customer satisfaction
  4. Linear Features (the more the better) • Features where customer

    satisfaction directly correlates with performance / quantity • Often related to product value
  5. Exciters & Delighters • Provide great satisfaction • Often adding

    a value premium • Lack of these feature will not decrease customer satisfaction below neutral • Often known as “unknown needs” because users don’t know they need them until they see them
  6. Assessing themes on the Kano Model Don’t guess! Ask your

    users by employing Kano’s functional / dysfunctional forms*. 
 
 Q. If you can add a profile photo how do you feel?
 Q. If you cannot add a profile photo how do you feel? 1. I expect it to be that way 2. I like it that way 3. I am Neutral 4. I can live with it that way 5. I dislike it that way ! * you may only need to ask 20 / 30 users to accurately prioritise requirements (Griffin & Hauser “voice of the user”1993)
  7. Talking to users If you can add a profile photo

    how do you feel? I expect it to be that way I like it that way x I am Neutral I can live with it that way I dislike it that way If you cannot add a profile photo how do you feel? I expect it to be that way I like it that way I am Neutral I can live with it that way I dislike it that way X Functional form of question Dysfunctional form of question

  11. Discussion Questions • What are the benefits of Kano analysis

    and relative weighting in relation to some of our current projects? • What exciters are going into some of our current projects • Can you think of projects where there is a mix of exciters, linear features and must have features, and what are they?
