Kano Model: A Step-by-Step Guide to Prioritizing User Needs

In today's fast-paced and ever-evolving market, thorough market research is the cornerstone of introducing new product features that truly resonate with users. Developing innovative features is akin to navigating uncharted territory, and market research acts as the compass that guides businesses toward identifying user pain points, meeting their needs, and ultimately winning their loyalty. But how can companies accurately pinpoint user expectations and deliver features that excite and delight? Enter the Kano Model — a powerful tool that helps businesses classify and prioritize user needs effectively.

What is the Kano Model?

The Kano Model, introduced in 1979 by Professor Noriaki Kano of the Tokyo Institute of Technology, is a qualitative framework that categorizes customer preferences into five distinct types:

- Must-Be Needs (Basic): These are the essential features that customers expect as a given. If these needs are not met, customers will be extremely dissatisfied. However, fulfilling these needs does not necessarily increase satisfaction—it simply prevents dissatisfaction. 

- One-dimensional Needs (Performance): These needs have a linear relationship with customer satisfaction. The better the performance of these features, the higher the satisfaction, and vice versa. These are often the features customers explicitly ask for and compare when choosing between products.

- Attractive Needs (Excitement): These are the unexpected features that surprise and delight customers. When present, they significantly boost satisfaction, but their absence does not cause dissatisfaction because customers don’t expect them. These features often differentiate a product from its competitors.

- Indifference Needs (No difference): These are features that customers don’t care about one way or the other. Their presence or absence has no significant impact on customer satisfaction.

- Reverse Needs: These are features that, when present, actually decrease customer satisfaction. They represent things customers do not want or find unnecessary. Including these features can lead to frustration or dissatisfaction.

This model helps businesses understand the non-linear relationship between product performance and user satisfaction, enabling them to focus on features that matter most to their audience.

Practical Application: Tesla's Success with the Kano Model

A prime example of the Kano Model in action is Tesla (FasterCapital). The company has masterfully applied the model to its vehicle performance features, such as superior acceleration, range, and safety. For instance, Tesla's "Ludicrous Mode" — a feature that delivers extreme acceleration — falls under the Performance Requirements category. This feature not only excites high-performance enthusiasts but also sets Tesla apart from competitors. By continuously innovating and optimizing these features, Tesla has successfully met customer expectations and strengthened its market position.

How to Use the Kano Model in Practice: A Step-by-Step Guide

1. Questionnaire design

To apply the Kano Model, start by designing a survey that aligns with its principles. For example, if you're evaluating some features about a smartwatch, your questionnaire should include:

Positive Questions: "If this feature is present, how would you rate it?"

Negative Questions: "If this feature is absent, how would you rate it?"

Use the standard Kano response options:

Really like it

Take it for granted

Indifferent

Barely acceptable

Strongly dislike

Surveymars offers a professional Kano research model. Simply input all the features of your product that need to be researched, and it will generate corresponding questions. Create a professional market research questionnaire in just one minute!

2. Data Organization and Categorization

Once the data is collected, categorize the responses into the five Kano categories. The category with the highest percentage for a specific feature determines its classification.

3. Calculating the Better-Worse Coefficients

The Better coefficient (Satisfaction Improvement Coefficient) and Worse coefficient (Satisfaction Reduction Coefficient) are calculated as follows:

Better Coefficient: (Performance + Excitement) / (Basic + Performance + Excitement+ Indifference)

Worse Coefficient: [(Basic+ Performance) / (Basic + Performance + Excitement + Indifference) x (-1)

For example, if your data shows:

Basic = 20

Performance = 30

Excitement = 30

Indifference = 10

Reverse = 10

Then:

Better Coefficient = (30 + 30) / 100 = 0.6

Worse Coefficient = [(20 + 30) / 100] x (-1) = -0.5

4. Interpreting the Results

Better Coefficient (0.6): Indicates a 60% chance that the video call feature will improve user satisfaction.

Worse Coefficient (-0.5): Suggests a 50% chance that the absence of this feature will decrease satisfaction.

By analyzing these coefficients, businesses can prioritize features that have the highest impact on satisfaction and minimize the risk of dissatisfaction.
