Unveiling Customer Needs with the Kano Model: Product Managers Guide to Prioritization

In the dynamic landscape of product development and service design, understanding customer needs is the cornerstone of success. The Kano model stands as a powerful tool for dissecting and categorizing these needs into distinct categories: basic, performance, and attractive. In this blog post, we'll explore the Kano model and delve into the detailed steps of constructing a Kano matrix to decipher customer preferences effectively.

Understanding the Kano Model

The Kano model, devised by Dr. Noriaki Kano in the 1980s, offers a structured approach to understanding customer satisfaction and dissatisfaction. It classifies customer requirements into three main categories:

1. Basic Needs: These are essential features that customers expect as a minimum requirement. Their absence leads to dissatisfaction, but their presence does not necessarily enhance satisfaction.

2. Performance Needs: These features directly impact customer satisfaction. As their performance improves, satisfaction increases, but their absence does not necessarily lead to dissatisfaction.

3. Attractive Needs: These are unexpected or innovative features that delight customers when present but don't necessarily cause dissatisfaction when absent. Their presence can differentiate a product or service and foster customer loyalty.

Steps to Constructing a Kano Matrix

Step 1: Identify Potential Features or Attributes

Begin by brainstorming a list of potential features or attributes relevant to your product or service. These could be gathered through market research, customer feedback, or team discussions.

Step 2: Develop Survey Questions

Craft survey questions to gauge customer preferences for each feature. Use a combination of direct and indirect questions to uncover both explicit and implicit needs.

Step 3: Conduct Customer Surveys

Distribute the surveys to a representative sample of your target audience. Ensure that the surveys are designed to elicit honest and detailed responses from participants.

Step 4: Analyze Survey Responses

Once you've collected survey responses, analyze the data to determine how customers perceive each feature. Pay attention to the level of satisfaction or dissatisfaction expressed for each attribute.

Step 5: Construct the Kano Matrix

Based on the survey data, construct the Kano matrix by plotting each feature along two axes: customer satisfaction and feature implementation. Classify features into one of the following categories:

• Must-Be Quality: Basic needs that customers expect as a minimum requirement.
• One-Dimensional Quality: Performance needs where satisfaction increases with improved performance.
• Attractive Quality: Features that provide unexpected delight and differentiation.

Step 6: Interpret the Results

Interpret the results of the Kano matrix to prioritize feature development and allocation of resources. Focus on enhancing must-be qualities, improving performance qualities to meet or exceed customer expectations, and innovating to introduce attractive qualities that differentiate your offering.

Example: Applying the Kano Model to Buying a Car

Let's illustrate the application of the Kano model with an example in the context of buying a car:

• Must-Be Quality: Customers expect essential safety features such as airbags, anti-lock braking system (ABS), and stability control. Their absence would lead to immediate dissatisfaction and compromise safety.

• One-Dimensional Quality: Performance features like fuel efficiency, engine power, and interior comfort directly influence customer satisfaction. As these features improve, satisfaction increases, but their absence does not necessarily lead to dissatisfaction.

• Attractive Quality: Innovative features such as advanced driver-assistance systems (ADAS), smartphone integration, and voice-controlled infotainment systems provide unexpected delight to customers. While not essential, their presence can differentiate a car model and attract tech-savvy buyers.

How is Kano Surveys and Matrix structured?

To demonstrate how Kano surveys are structured and how the Kano matrix is calculated, let's consider an example scenario in the context of a smartphone app for a ride-sharing service. We'll outline sample survey questions and then illustrate how responses are analyzed to create a Kano matrix.

Sample Kano Survey Questions:

1. Question for Must-Be Quality:

   • How important is it for you that the ride-sharing app provides accurate arrival time estimates?
     • Very Important
     • Somewhat Important
     • Neutral
     • Not Very Important
     • Not Important at All

2. Question for One-Dimensional Quality:

   • How satisfied would you be if the ride-sharing app offered various payment methods (e.g., credit card, PayPal, mobile wallets)?
     • Very Satisfied
     • Satisfied
     • Neutral
     • Dissatisfied
     • Very Dissatisfied

3. Question for Attractive Quality:

   • How would you feel if the ride-sharing app provided a gamified loyalty program where users earn points for every ride and can redeem them for discounts or free rides?
     • Delighted
     • Pleased
     • Neutral
     • Unhappy
     • Angry

Sample Matrix Calculation:

Let's assume we collected survey responses from 100 users for each question and categorized their responses based on the Likert scale. Here's how we can calculate the Kano matrix:

Must-Be Quality:

• Very Important: 70 respondents
• Somewhat Important: 20 respondents
• Neutral: 5 respondents
• Not Very Important: 3 respondents
• Not Important at All: 2 respondents

Satisfaction Score: 100% of Very Important respondents are satisfied, while 0% of the other respondents are satisfied.

One-Dimensional Quality:

• Very Satisfied: 40 respondents
• Satisfied: 30 respondents
• Neutral: 15 respondents
• Dissatisfied: 10 respondents
• Very Dissatisfied: 5 respondents

Satisfaction Score: Calculate the weighted average satisfaction score based on the Likert scale responses.

Attractive Quality:

• Delighted: 25 respondents
• Pleased: 30 respondents
• Neutral: 20 respondents
• Unhappy: 15 respondents
• Angry: 10 respondents

Satisfaction Score: Calculate the weighted average satisfaction score based on the Likert scale responses.

Constructing the Kano Matrix:

Based on the calculated satisfaction scores for each question, we can plot the features on the Kano matrix:

• Must-Be Quality: High customer satisfaction, as the feature is expected.
• One-Dimensional Quality: Linear relationship between satisfaction and feature performance.
• Attractive Quality: Satisfaction peaks at a certain point but diminishes with excessive implementation.

By analyzing the Kano matrix, the product managers can prioritize features accordingly:

• Must-Be Quality features should be ensured to meet customer expectations.
• One-Dimensional Quality features should be optimized to enhance customer satisfaction.
• Attractive Quality features can be strategically introduced to surprise and delight customers.
