Kano Model: How to Prioritise Product Features (With Example)

Quick Overview

• The Kano model is a product management framework that classifies product features based on their impact on customer satisfaction. It helps teams understand customer expectations and prioritise features that deliver meaningful value.
• Categories of the Kano model: The five categories are must-be features (basic expectations), performance features (improve satisfaction as performance increases), attractive features (unexpected benefits), indifferent features (have little impact on satisfaction), and reverse features (some customers dislike them).
• How does the Kano model work? It uses functional and dysfunctional survey questions to understand how customers feel when a feature is available and when it is absent. Teams combine the responses using a Kano evaluation matrix to classify each feature.
• This guide explains what the Kano model is, its five feature categories, how the evaluation process works, and how product managers can use practical examples from mobile apps, e-commerce platforms, and smartphones to prioritise features and improve product roadmaps.

What is the Kano model?

The Kano model is a product management framework that helps classify product features based on their impact on customer satisfaction. Developed by Japanese professor Noriaki Kano, it explains how different product attributes influence how customers feel about a product.

The framework groups features into five categories: must be, performance, attractive, indifferent, and reverse. Each category represents a different relationship between a product feature and customer satisfaction.

Product managers use the Kano model to:

• Understand what customers expect from a product.
• Identify features that have the greatest impact on satisfaction.
• Separate essential requirements from additional features.
• Avoid spending resources on features customers do not value.
• Make more informed product development decisions.

What is the purpose of the Kano model in product management?

The main purpose of the Kano model in product management is to help teams understand which product features matter most to customers. It provides a customer focused way to evaluate feature ideas instead of prioritizing them only based on business assumptions or internal preferences.

Its key uses include:

• Feature prioritization: Helps product managers decide which features should receive attention first.
• Customer satisfaction: Identifies features that can improve the overall product experience.
• Product planning: Supports better decisions when creating or updating a product roadmap.
• Resource allocation: Helps teams avoid investing too much time in features with limited customer value.
• Competitive differentiation: Highlights opportunities to introduce features that customers may not expect but appreciate.

What are the five categories of the Kano model?

The Kano model divides product features into five categories based on how they influence customer satisfaction. Understanding these categories helps product teams distinguish between basic expectations and features that can make a product stand out.

Must be features: Basic customer expectations

Must be features are the basic requirements customers expect a product to have. Customers may not feel especially satisfied when these features are available, but their absence can cause significant dissatisfaction.

For example, customers expect an e-commerce platform to process payments securely. If the payment system does not work properly, customers are likely to lose trust in the platform.

Common characteristics include:

• Customers consider these features essential.
• Their presence is often taken for granted.
• Their absence creates dissatisfaction.
• They should be addressed before optional enhancements.

Performance features: Requirements that increase satisfaction

Performance features are attributes where customer satisfaction generally increases as the product performs better. Customers notice these features and often compare them when choosing between competing products.

For example, smartphone users may value longer battery life. A phone that lasts longer between charges can offer a better experience.

Key characteristics include:

• Better performance generally leads to greater satisfaction.
• Customers can compare these features across products.
• They often influence purchasing decisions.
• Their improvement can strengthen a product's competitive position.

Attractive features: Unexpected features that delight customers

Attractive features are additional benefits that customers do not necessarily expect. Their presence can create a positive impression, while their absence usually does not cause dissatisfaction.

For example, a mobile banking app that offers personalized spending insights may pleasantly surprise users.

These features are useful because they can:

• Create a memorable customer experience.
• Differentiate a product from competitors.
• Exceed basic customer expectations.
• Encourage customers to explore more product capabilities.

Indifferent features: Features that do not affect customer satisfaction

Indifferent features are product attributes that have little or no impact on customer satisfaction. Customers generally do not care whether these features are available.

For example, a rarely used customization option may not influence how customers evaluate a product.

Product teams should examine these features carefully because they may consume development time without creating meaningful customer value.

Reverse features: Features that some customers dislike

Reverse features are attributes that can reduce customer satisfaction when they are included. Some customers may prefer a simpler product experience and dislike additional functionality.

For example, users who prefer a clean mobile interface may find excessive notifications or complicated menus frustrating.

Product managers should consider:

• Whether a feature creates unnecessary complexity.
• Whether different customer groups have different preferences.
• Whether the feature should be optional.
• Whether removing or simplifying it could improve the experience.

How does the Kano model work?

The Kano model works by collecting customer feedback about individual product features and classifying each feature according to the responses. It uses two questions for every feature to understand how customers feel when the feature is present and when it is absent.

The results help product managers identify which features meet basic expectations, increase satisfaction, or have little value to customers.

1. Functional and dysfunctional customer survey questions

A Kano survey uses two types of questions to evaluate each product feature.

• Functional question: Asks how customers would feel if a particular feature were available.
• Dysfunctional question: Asks how customers would feel if the same feature were not available.

For example, a product team evaluating a dark mode option might ask:

• Functional: How would you feel if this app offered a dark mode?
• Dysfunctional: How would you feel if this app did not offer a dark mode?

Customers can select responses such as:

• I like it.
• I expect it.
• I am neutral.
• I can tolerate it.
• I dislike it.

2. Kano evaluation matrix for classifying product features

The Kano evaluation matrix is used to interpret the answers to functional and dysfunctional questions. It combines the two responses to determine the category of a product feature.

The matrix helps classify features into the five categories:

• Must be
• Performance
• Attractive
• Indifferent
• Reverse

3. Customer responses and feature classification

After collecting survey responses, product teams compare the answers for each feature using the evaluation matrix. The most suitable category is assigned based on the response combinations.

For example:

• If customers expect a feature and become dissatisfied without it, it may be classified as must be.
• If satisfaction improves when a feature is available, it may be classified as performance.
• If customers appreciate a feature they did not expect, it may be classified as attractive.
• If customers show little interest either way, it may be classified as indifferent.
• If customers prefer the product without a feature, it may be classified as reverse.

How to use the Kano model to prioritize product features

Product managers can use the Kano model as part of their feature prioritization process. It helps teams move from collecting ideas to understanding which features are likely to deliver the most customer value.

The process involves identifying possible features, collecting customer feedback, evaluating responses, and validating priorities before adding features to the roadmap.

1. Identify potential product features

Start by creating a list of features that could improve the product. These ideas may come from customer feedback, support requests, market research, competitor analysis, or internal product discussions.

While preparing the list:

• Focus on features connected to customer needs.
• Include both essential requirements and potential enhancements.
• Avoid adding unrelated ideas to the same evaluation.
• Make sure each feature is clearly described.

2. Design and conduct Kano surveys

Once the feature list is ready, prepare functional and dysfunctional questions for every feature. Keep the questions simple so customers can understand what they are being asked.

For better survey results:

• Use clear and unbiased language.
• Ask both functional and dysfunctional questions.
• Provide consistent response options.
• Collect feedback from relevant customer groups.
• Avoid making the survey unnecessarily long.

3. Analyze customer responses and classify features

After the survey, review the responses and use the evaluation matrix to classify each feature. This helps teams understand which product attributes are essential, which improve satisfaction, and which may not be worth developing.

During analysis:

• Group responses according to the five categories.
• Look for patterns across different customer groups.
• Identify features with mixed or unexpected responses.
• Review the number of responses supporting each classification.
• Investigate differences in customer preferences.

4. Prioritize features based on customer satisfaction

Use the classifications to decide which features deserve attention. Must be features usually need to be addressed first, while performance features can be prioritized based on their expected customer value.

A practical approach is to:

• Address essential customer expectations.
• Evaluate performance features based on their impact and development effort.
• Consider attractive features that can differentiate the product.
• Reassess indifferent features before allocating resources.
• Be cautious about reverse features that may create a poor experience.

5. Validate priorities before adding features to the product roadmap

Before finalizing the product roadmap, validate the shortlisted features with relevant stakeholders and available product data. Customer preferences are important, but they should be considered alongside business requirements and technical constraints.

Check whether:

• The feature supports the product strategy.
• The expected customer benefit justifies the development effort.
• The team has the resources to build and maintain it.
• The feature fits the product's current priorities.
• Further customer testing is required.

What is an example of the Kano model?

The Kano model becomes easier to understand when applied to familiar products. The following examples show how different features can fall into different categories depending on customer expectations and preferences.

1. Kano model example for a mobile app

Consider a mobile banking app that wants to improve its user experience. The product team collects customer feedback about several possible features.

The features may be classified as follows:

• Must be: Secure login and reliable account access.
• Performance: Faster transaction processing and quicker app loading.
• Attractive: Personalized spending insights and smart savings suggestions.
• Indifferent: Decorative interface animations that do not improve usability.
• Reverse: Frequent promotional notifications that some users find distracting.

2. Kano model example for an e-commerce platform

An e-commerce platform wants to improve the shopping experience and understand which features customers value most.

Its features could be grouped as follows:

• Must be: Secure payment processing and accurate order information.
• Performance: Faster delivery and more accurate product search results.
• Attractive: Personalized product recommendations and early access to selected offers.
• Indifferent: Additional decorative elements that do not improve shopping.
• Reverse: Too many pop ups or promotional messages that interrupt browsing.

3. Kano model example for a smartphone

A smartphone manufacturer is planning its next product release and wants to understand which features matter to buyers.

Possible classifications include:

• Must be: Reliable calling, basic security, and a functional operating system.
• Performance: Battery life, camera quality, and processing speed.
• Attractive: Innovative camera modes or useful AI powered features.
• Indifferent: Features that customers rarely notice or use.
• Reverse: Unwanted preinstalled apps or unnecessary notifications.

4. Kano model feature prioritization matrix

A feature prioritization matrix brings the survey findings together so product managers can compare different features and make decisions.

The following table illustrates how a team might organize its findings:

Feature category	Customer response	Suggested priority
Must be	Expected as a basic requirement	Address first
Performance	Satisfaction increases with better performance	Prioritize based on impact
Attractive	Creates unexpected satisfaction	Consider for differentiation
Indifferent	Has little effect on satisfaction	Lower priority
Reverse	May reduce satisfaction	Review or make optional

Conclusion

The Kano model helps product managers and development teams understand customer expectations and prioritize features based on their impact on satisfaction. It is especially useful when teams have multiple feature ideas but limited time and resources.

However, customer preferences should not be the only factor in product decisions. Consider business goals, development costs, and technical feasibility before finalizing the product roadmap. Start by collecting customer feedback and classifying features into the five Kano categories to focus on what customers truly value.
