Getting Started

Based on the characteristics and features of their goods or services, businesses can better understand and classify customer satisfaction with the aid of the Kano Model. Developed by Professor Noriaki Kano in the 1980s, this model is a valuable tool for identifying which features significantly impact customer satisfaction and which have little or no effect. 

This article thoroughly explores the Kano Model, including its categories, benefits, challenges, and practical applications. It allows you to expedite your process to deeply understand your customers’ desires. 

What is the Kano Model?

Origin and Definition

Japanese professor Dr. Noriaki Kano introduced the Kano Model to classify customer preferences into different categories. The model is built on the premise that not all product features contribute equally to customer satisfaction, and some may even lead to dissatisfaction if not implemented correctly.

Purpose of the Kano Model

Organizations can use the Kano Model to understand better how various features impact customer satisfaction and thus prioritize product development efforts. That way, efforts can be directed toward completing features with the most significant potential for impact.

Focus on basic, performance, and excitement features to enhance customer experience.

Key Categories of the Kano Model

Must-be, one-dimensional, attractive, and indifferent attributes impact customer satisfaction differently.

1. Must-Be Attributes

Must-be attributes are the fundamental features that consumers look for in a good or service. While their presence does not substantially raise satisfaction, their absence causes discontent.

Examples
The braking system of a car.
Fundamental hotel hygiene standards.

2. One-Dimensional Attributes

Customer satisfaction is directly correlated with one-dimensional attributes. The better the performance of these attributes, the higher the satisfaction.

Examples
Higher ISP internet speeds.
More efficient use of petrol in vehicles.

3. Attractive Attributes

Features that delight customers but are unexpected are considered attractive attributes. Their absence won’t make you unhappy, but having them around will make you happier than you would be otherwise.

Examples
Complimentary snacks on a flight.
Personalized recommendations on a streaming platform.

4. Indifferent Attributes

Indifferent attributes are features that neither increase nor decrease customer satisfaction. They have little impact on the customer experience.

Examples
The color of packaging for most products.
A minor app interface detail that goes unnoticed.

5. Reverse Attributes

Reverse attributes are characteristics that are favoured by certain customers and despised by others. Their effect is contingent upon the intended receivers’ tastes and preferences.

Examples
Options for customization are complex and may be overwhelming for users who are not tech-savvy.
Products with a too minimalist design and no clear instructions to users.

How to Use the Kano Model

Identify features, conduct surveys, analyze results, and prioritize must-have & one-dimensional attributes.

Step 1: Identify Features

Make sure to include all the features or attributes you want to evaluate in your list. Both current and future features could be a part of this.

Step 2: Conduct Customer Surveys

Use Kano surveys to gather customer feedback. These surveys typically include paired questions for each feature:

  • Functional: How do you feel if this feature is present?
  • Dysfunctional: How do you feel if this feature is absent?

Step 3: Analyze Survey Results

Categorize features based on customer responses into one of the five Kano categories. This helps prioritize features according to their impact on satisfaction.

Step 4: Prioritize Development

Focus on implementing Must-Be and One-Dimensional attributes first. Next, look into appealing attributes to boost customer satisfaction.


Benefits of the Kano Model

1. Improved Customer Satisfaction

Businesses can maximize customer satisfaction by tailoring their offerings directly to the customer’s core needs.

2. Resource Optimization

The model helps focus available resources on your product or service’s most critical features – allowing you to build a more impactful MVP if the budget is limited and the product or service is not market-tested.

3. Competitive Advantage

Adding attractive attributes can differentiate a product or service in a congested or highly competitive market.

4. Strategic Decision-Making

The Kano Model prioritizes features and develops products using data, processes, and detailed feedback in a self-improving loop.

Improves satisfaction & optimization but has data complexity & implementation costs.

Common Challenges with the Kano Model

1. Complexity in Data Collection

Planning is necessary, and creating and carrying out Kano surveys can take time.

2. Subjectivity in Responses

Accurately classifying features can be challenging due to the subjective nature of customer preferences.

3. Changing Customer Expectations

Customer anticipations evolve over time, requiring regular updates to the analysis.

4. Overemphasis on Delightful Features

Focusing too much on Attractive attributes can lead to neglect of Must-Be or One-Dimensional features.
