Kano Model in Surveys: How to Understand Customer Expectations and Exceed Them

Developed by Japanese professor Noriaki Kano in the 1980s, the model has become one of the key tools for analyzing customer expectations. Today, it is used in marketing, product management, and customer experience research, helping companies not just meet but exceed customer expectations.

The Essence of the Kano Model: Understanding What Matters to the Customer

The model classifies customer requirements into three groups:

• Basic (must-be) — mandatory functions or qualities without which the product is not perceived as complete. Their fulfillment does not cause delight, but their absence causes dissatisfaction.
• Performance (one-dimensional) — parameters that directly influence the level of satisfaction. The better a company meets these requirements, the higher the customer's rating.
• Delighters (attractive) — unexpected yet pleasant characteristics capable of evoking strong positive emotions and increasing loyalty.

This approach helps businesses see the product through the customer's eyes and assess not only the quality of execution but also the emotional component of the customer experience.

Why Businesses Should Use the Kano Model

Applying the Kano model provides companies with strategic advantages. It helps:

• determine product and service development priorities;
• understand which characteristics truly influence customer satisfaction;
• optimally allocate resources between maintaining basic functions and implementing innovations;
• identify opportunities for creating a unique customer experience.

Thus, the Kano model becomes a planning and decision-making tool that allows building strategy not on intuition, but on data and audience behavior.

Who Benefits from This Tool

The Kano model is relevant for specialists working with customer experience, service quality, and product strategy:

• Marketers — for evaluating audience response to a product;
• Product managers — for determining development priorities;
• CX analysts — for structural analysis of feedback;
• Heads of service departments — for increasing customer satisfaction levels.

Using this approach, businesses gain a tool that helps not just eliminate dissatisfaction, but build a sustainable emotional connection with the customer.

Principles of the Kano Model: Three Levels of Customer Needs

The Essence of the Kano Model Principles

The principles of the Kano model are based on understanding that all customer needs differ in their degree of influence on satisfaction. Some product features are considered mandatory, others directly affect the perception of quality, and still others can create delight and form emotional loyalty.

Dividing requirements into three levels helps companies see the product through the consumer's eyes and understand where to focus efforts to increase value and competitiveness.

1. Basic (Must-Be) Requirements

Basic requirements are the foundation without which the customer will not be satisfied, even if all other characteristics are of high quality. They are taken for granted: their fulfillment does not elicit gratitude, but their absence leads to strong dissatisfaction.

Examples:

• For a bank — stable operation of a mobile app and transaction security.
• For a hotel — room cleanliness and availability of hot water.
• For an online store — accuracy of product information and delivery times.

Companies that ignore basic requirements lose customer trust. Therefore, these aspects must be unconditionally fulfilled before implementing additional improvements.

2. Performance (One-Dimensional) Requirements

Performance requirements are parameters that directly affect the customer's level of satisfaction. The better a company meets them, the higher the perceived product quality.
These expectations are formed based on market standards, reviews, competitor experience, and customers' personal preferences.

Examples:

• For an online delivery service — fast and accurate delivery at the chosen time.
• For an internet platform — convenient navigation and a clear interface.
• For an educational project — access to materials without delays and competent feedback from instructors.

Correctly identifying performance requirements helps companies retain customers and increase their loyalty. If these expectations are not met, the customer quickly switches to competitors.

3. Delighter (Attractive) Requirements

Delighter requirements are those product characteristics that are not expected by the customer but evoke strong positive emotions when present. They create a surprise-and-delight effect, enhance trust, and form an emotional connection with the brand.

Examples:

• A free room upgrade upon hotel check-in.
• Personalized recommendations or gifts for regular customers.
• A convenient additional feature the user didn't even anticipate but now considers indispensable.

Such factors often become key for brand differentiation in a competitive market. They not only increase satisfaction but also create that added value for which customers are willing to pay more.

Why It's Important to Distinguish Between Requirement Levels

A clear understanding of the three requirement categories allows businesses to:

• Set product development priorities wisely;
• Avoid overspending resources on features that do not affect perceived value;
• Identify areas for innovation and customer "delight".

How to Apply the Kano Model in Customer Surveys

Why Use Surveys Based on the Kano Model

Applying the Kano model in surveys allows companies to understand which product characteristics truly shape customer satisfaction, and which remain unnoticed.
This approach turns a survey from a mere opinion-gathering tool into a full-fledged method for analyzing customer expectations and perceived value.

Surveys based on the Kano model help:

• Determine which features are considered basic and which are perceived as competitive advantages;
• Assess which improvements will bring the maximum effect;
• Set priorities when developing a product or service.

Survey Structure: Three Types of Questions

For a Kano model survey to be effective, it's important to include questions corresponding to all three requirement levels — basic, performance, and delighter.

1. Questions About Basic Requirements

Goal — To identify how well minimum customer expectations are met.
Example:

• "Was the information about the product or service clear and up-to-date?"
• "Did the product quality meet your expectations?"

Such questions help determine if there are problems in the fundamental aspects of customer interaction.

2. Questions About Performance Requirements

Goal — To measure the degree of satisfaction with key parameters.
Example:

• "How satisfied are you with the service speed?"
• "How convenient was the ordering or registration process?"

Answers show where the business meets standards and where improvement is needed.

3. Questions About Delighter Requirements

Goal — To identify hidden opportunities for a "wow-effect."
Example:

• "What additional functions or services would make our product perfect for you?"
• "What would you like to receive from us as a pleasant bonus?"

Such questions reveal what customers usually don't voice but what can become a driver of loyalty.

How to Use Survey Results

After collecting responses, the data is analyzed in terms of the three requirement categories.

• If the score on basic questions is low — deficiencies need to be addressed.
• If customers express dissatisfaction with performance requirements — processes should be reviewed.
• If strong reactions to "delighter" factors are identified — this is an area for investment and strengthening competitive advantage.

How to Analyze Survey Results Using the Kano Model

Why Analyze Results with the Kano Model

Conducting a survey is only the first part of the work. The main value of the Kano model emerges at the analysis stage, when customer responses help determine which product or service characteristics influence satisfaction the most.

Analyzing data with this model allows businesses to:

• classify requirements by their degree of influence on perceived quality;
• determine which functions bring real value and which are excessive;
• build an improvement strategy based on facts, not assumptions.

Step 1. Classifying Responses by Requirement Type

The first stage of analysis is distributing responses into the three categories of the Kano model:

1. Basic requirements — aspects without which the customer will be dissatisfied, even if everything else is perfect.

Example: if a customer complains about payment errors, this signals a breach of the basic level.

2. Performance requirements — parameters that directly influence the level of satisfaction.

 Example: order processing speed, staff courtesy, quality of feedback.

3. Delighter requirements — unexpected features or services that evoke positive emotions.

Example: a gift with purchase, personalized recommendations, or individual bonuses.

Classification helps see which product elements need refinement and which can become loyalty tools.

Step 2. Interpreting Data and Determining Priorities

At this stage, it is important to determine which factors have the maximum impact on customer expectations.

• High scores on basic questions indicate product stability.
• Medium scores indicate a risk of dissatisfaction as competition grows.
• Low scores indicate a need for urgent improvements.

Next, aspects that cause "delight" are identified — these are precisely what give a business the opportunity to stand out in the market. Companies that notice these signals in time are able not only to satisfy customers but to create a unique interaction experience.

Step 3. Visualizing and Analyzing Results

For effective analysis, it's important not only to collect data but to present it clearly. Visualization helps quickly assess which requirement categories need attention and which are already being met at a high level. Typical visualization tools include Kano diagrams, priority matrices, and satisfaction graphs.

Using such reports, analysts and product managers can easily present results to the team and visually show which changes will bring the greatest effect.

Advantages of Using the Kano Model in Marketing and Product Management

Why the Kano Model is Important for Business

In a highly competitive environment, companies can no longer limit themselves to just product quality — they need to understand what customers truly value. The Kano model helps approach this question systematically, turning subjective feedback into concrete data that can be used for managerial decisions.

Thanks to this approach, businesses gain the ability not just to eliminate customer dissatisfaction, but to create factors that evoke delight and form emotional loyalty.

1. Improving Product and Service Quality

One of the main advantages of the Kano model is its ability to precisely determine which product characteristics truly influence customer satisfaction.

• Basic requirements ensure perception stability and trust in the brand.
• Performance requirements help retain customers through predictable and comfortable interaction.
• Delighter requirements turn customers into loyal brand advocates, boosting word-of-mouth and recommendations.

Applying the Kano model helps identify product weaknesses, improve service quality, and enhance the user experience.

2. Deep Understanding of Customer Expectations

Using the principles of the Kano model, companies can gain a deeper understanding of what customers actually expect. Surveys built on this model allow not just measuring satisfaction levels, but revealing the structure of expectations — from basic to delightful.

Example: A company might discover that for customers, not only delivery speed is important, but also pleasant details like a personal notification or a small bonus. These elements become the key to building trust and increasing brand value.

This approach makes marketing and product management strategies oriented towards real customer expectations, not the team's assumptions.

3. Identifying Factors That Create Competitive Advantage

Delighter requirements are a source of innovation and the key to brand differentiation. The Kano model helps uncover hidden drivers of loyalty — those characteristics customers don't expect but value the most.

Examples:

• implementing additional features that save the customer's time;
• creating personalized services;
• using unexpected bonuses and privileges.

Such solutions allow a brand to move beyond standards and offer the customer something unique that competitors cannot replicate.

4. Improving Strategic Planning

The results of Kano model analysis give companies a tool for intelligent resource allocation.
They allow:

• focusing on functions that bring the greatest effect;
• abandoning excessive improvements that do not affect product perception;
• building development and communication priorities based on real data.

Conclusion

Modern companies no longer limit themselves to standard satisfaction research — it's important for them to understand what exactly creates value for the customer. The Kano model provides this answer, turning feedback into a strategic planning tool. It helps determine which product characteristics are necessary, which increase satisfaction, and which are capable of evoking delight and emotional attachment.

This approach makes conscious product development possible: a business doesn't just react to complaints, but proactively shapes an experience that customers remember and value.

Using the Kano model allows companies to rely on data when making decisions. Based on the analysis, one can:

• identify product or service development priorities;
• direct resources towards improvements that bring the greatest effect;
• strengthen competitive advantage through an understanding of customer expectations;
• increase loyalty levels and build trust in the brand.

The Kano model doesn't just measure satisfaction — it helps predict customer behavior and develop strategies based on real needs.
