The document discusses the Kano model for product development. The Kano model classifies product features into three categories: basic/hygiene factors, performance factors, and excitement/delight factors. It provides a framework to evaluate features based on these categories, estimated technical effort, business benefits and costs, and time sensitivity to prioritize development. The goal is to identify high return on investment features by focusing first on critical hygiene needs, then highly attractive delight factors, and high value-added performance features. Over time, excitement needs may become performance needs and then basic needs, so features and needs are not timeless.

7. About KANO MODEL
by Kanō Noriaki (狩野紀昭 )
Kano challenged the conventional beliefs
that improving each attribute of a
company's product or service will lead to
increased customer satisfaction.
Kano believed that not all attributes of
product or service performance are equal
in the eyes of the customer, and that some
attributes create higher levels of customer
satisfaction than others.
8. 3 Core Tenets
1. Value attracts customers
2. Quality keeps customers & build loyalty
3. Innovation is necessary to differentiate and
compete in the market
9. 2 Dimension
Customer very satisfied
Level of Satisfaction
Execution Quality
Executed poorly Executed
or not at all very well
Customer very dissatisfied
10. 3 Core Type of Attribute
1. Hygiene
2. Performance
3. Excitement
12. Kano Model
Customer very satisfied
Executed poorly Executed
or not at all very well
Hygiene
Satisfying basic minimizes
dissatisfaction. Absence
or poor execution leads to
great dissatisfaction.
Customer very dissatisfied
13. Hygiene
Absence of these features will cause dissatisfaction,
but no amount of execution quality will cause positive
satisfaction, it will only minimize dissatisfaction
14. Hygiene – Example
No toilet roll in cubicle Very dissatisfied
10 toilet roll in cubicle Okay, so what?
No forget password Dissatisfied
Super efficient password recovery Okay, move on
15. Hygiene - Nature
Nothing exciting Customer unlikely to list it as its
expected
Uncover by studying the environment and observe
repeating pattern
16. Performance
Need that are consciously evaluated by the
customer and at the top of their minds when
evaluating a product
17. Kano Model
Customer very satisfied
Performance
Performance needs yield a
proportional satisfaction for an
investment in execution quality
Executed poorly Executed
or not at all very well
Customer very dissatisfied
18. Performance
Satisfaction is proportional to the quality of the
feature.
Poor quality WTF? Why even bother?
Standard quality Didn’t notice it was there before
Good quality Ahh, this is how it should be done
19. Performance – Example
Low car mileage WTF? It suck like a jetplane
minus the speed
High car mileage Let’s drive across the road!
Website loading time 30 sec Why am I still here?
Website loading time 0.005 sec Why is not every
site like that?
22. Kano Model
Customer very satisfied Delight
Excitement needs delight when
present but no dissatisfaction
when not
Executed poorly Executed
or not at all very well
Customer very dissatisfied
23. Delight
Presence of these will delight customer and increase
satisfaction. Absence won’t cause dissatisfaction.
24. Delight – Example
Internet access on plane Holy sh*t! I can
Facebook if this plane got highjack!
24 hr online chat support Awesome!
25. Delight - Nature
Really hard to come by. Require an understanding of
‘latent need’ which can only really be understood
through observation or incredible genius intuition.
26. Basic Kano Model Delight Excitement needs delight when
Customer very satisfied present but no dissatisfaction
when not
Performance
Performance needs yield a
proportional satisfaction for an
investment in execution quality
Executed poorly Executed
or not at all very well
Hygiene
Satisfying basic minimizes
dissatisfaction. Absence or poor
execution leads to great
dissatisfaction.

33. Which has better ROI?
Customer very satisfied Highly attractive
High Value Added
Executed poorly Executed
or not at all very well
Critical
Customer very dissatisfied
34. Which to focus?
1. Fulfil the Critical
2. Pick a few Highly Attractive
3. Spend more effort on a few High Value Added
As the gradient become gentler, it means ROI is
low. This might be a feature you want to drop.

38. So I just choose based on
ROI for user, business and
effort right?
39. Almost… but
Over time, excitement needs become
performance needs, then basic needs.
The innovations of tomorrow, will become the
hygiene factors of yesterday
