One of our core responsibilities is to make informed decisions about which features and enhancements to prioritize for our product roadmaps. Getting this right can mean the difference between a successful product that resonates with users or one that falls flat.
That’s where the Kano Model comes in. Developed in the 1980s by Dr. Noriaki Kano, a Japanese professor and management consultant, the Kano Model provides a framework for categorizing and prioritizing customer needs and preferences for a given product or service.
By truly understanding which attributes of your product are must-haves, which are differentiators, and which are insignificant to customers, you can focus your development efforts on the areas that will have the biggest positive impact.
In this guide to using the Kano Model, we’ll dive deep into what it is, how it works, and how to apply it effectively to make better product decisions that delight your customers.
Guide to Using the Kano Model for Better Product Decisions
What is the Kano Model?
The Kano Model posits that not all product attributes are created equal in the minds of customers. It classifies customer preferences for product capabilities into five primary categories:
1. Must-Be Attributes:
These are basic attributes that customers view as prerequisites or minimum requirements. If these fundamental needs aren’t met, customers will be extremely dissatisfied.
2. One-Dimensional Attributes:
These are attributes where customer satisfaction is proportional to how well the attributes are delivered or fulfilled. The more the attribute is present, the more satisfied the customer will be, and vice versa.
3. Attractive Attributes:
Also known as “delighters,” these are unexpected or unspoken attributes that go beyond customer expectations. Delivering on these can lead to high levels of customer satisfaction and product differentiation, but their absence doesn’t cause dissatisfaction.
4. Indifferent Attributes:
These are aspects of the product that don’t impact customer satisfaction one way or the other – customers don’t really care about them.
5. Reverse Attributes:
These are attributes where the presence of the attribute actually causes customer dissatisfaction. Think of features that are overly complex or intrusive.
By mapping customer needs and preferences to these categories, the Kano Model helps product teams visualize where to focus their efforts, which features to prioritize or eliminate, and how to optimize the product roadmap over time to maximize satisfaction.
The Benefits of Using the Kano Model
There are several compelling reasons why product managers should leverage the Kano Model:
1. Better Understanding of Customer Needs
The Kano Model provides a structured way to deeply understand what truly matters to your customers and segment those needs based on their impact on satisfaction. This level of insight allows you to prioritize your roadmap accordingly.
2. Differentiation and Competitive Advantage
By delivering on “attractive” attributes that competitors overlook, you can build a product that stands out and provides unexpected value and delight to customers. This differentiation gives you a competitive edge.
3. Improved Customer Satisfaction and Retention
When you focus on nailing the “must-be” and “one-dimensional” attributes while layering in “attractive” elements, you create a product experience that maximizes customer satisfaction. Satisfied customers are more likely to be loyal and stick with your product.
4. Optimized Resource Allocation
With the Kano Model’s categorization, you can avoid wasting resources on attributes that don’t actually matter to customers (“indifferent“) or risk irritating them (“reverse“). Your development efforts stay laser-focused.
5. Data-Driven Product Decisions
Rather than relying solely on intuition or assumptions, the Kano Model allows you to base product decisions on hard data about what customers actually want, need, and value.
How to Apply the Kano Model
While the core principles are straightforward, successfully implementing the Kano Model requires following a proven, structured process:
Step 1: Define the Decision Context
Start by clearly articulating the product, feature set, or specific enhancements you want to analyze through the Kano lens. Having this bounded context clarified upfront is crucial.
Step 2: Identify Potential Attributes
Brainstorm a comprehensive list of all the potential product capabilities, features, or attributes that could relate to your defined decision context. Leave no stone unturned during this stage – the goal is to capture as many attributes as possible.
Step 3: Gather Customer Feedback
This is where the rubber meets the road. You’ll need to collect customer feedback and requirements using carefully designed survey questions.
For each potential product attribute identified in Step 2, you’ll ask two questions:
Functional Question:
How would you feel if this attribute was present in the product? (With responses like “I would be happy,” “I wouldn’t care,” etc.)
Dysfunctional Question:
How would you feel if this attribute was not present in the product? (With the same response choices.)
The specific combinations of responses across the functional and dysfunctional questions will allow you to categorize each attribute based on the Kano Model, as we’ll see in Step 4.
When crafting your survey, keep these best practices in mind:
- Ask questions tailored to your specific product/features rather than generalized ones.
- Provide clear definitions and examples to ensure respondents understand each attribute.
- Use consistent scales and language throughout.
- Survey a representative sample of your target customers to get an accurate picture.
- Consider a mix of open-ended questions as well to gather additional context.
Step 4: Categorize Attributes Using the Kano Evaluation Model
With customer survey data in hand, it’s time to categorize each product attribute based on the responses according to the Kano Evaluation Model:
Must-Be Attributes:
If the dysfunctional response is “I would be extremely unhappy” and the functional response is “I wouldn’t care” or “I would be neutral.”
One-Dimensional Attributes:
If the dysfunctional response is “I would be extremely unhappy” and the functional response is “I would be happy.”
Attractive Attributes:
If the dysfunctional response is “I wouldn’t care” or “I would be neutral” and the functional response is “I would be extremely happy.”
Indifferent Attributes:
If both the functional and dysfunctional responses are “I wouldn’t care” or “I would be neutral.”
Reverse Attributes:
If the functional response is “I would be extremely unhappy” and the dysfunctional response is “I would be happy” or any other combination of responses that indicates a negative reaction to the attribute’s presence.
It’s best to map out each attribute on a table or matrix to visualize where it falls within the various Kano categories.
Step 5: Prioritize and Act
With attributes categorized based on customer preferences, you can now prioritize your product decisions for maximum impact:
1. Ensure All Must-Be Attributes Are Met:
These are absolute requirements – if you don’t have these covered, customers won’t be satisfied at all.
2. Focus on Strengthening One-Dimensional Attributes:
These attributes directly correlate to satisfaction, so improving them should be a priority.
3. Identify Opportunities to Deliver Attractive Attributes:
Look for low-hanging fruit and differentiated “delighters” you can build to exceed expectations.
4. Eliminate Reverse and Insignificant Attributes:
Don’t waste resources on attributes that frustrate customers or that they simply don’t care about.
5. Rinse and Repeat:
As customer needs evolve, continue cycling through the Kano process to realign your product roadmap accordingly.
By following these prioritization guidelines informed by the Kano Model, you can optimize your roadmap to invest in the highest-impact areas for your customers.
Case Study: Using the Kano Model for Product Success
To illustrate the Kano Model in action, let’s walk through a simplified example in the context of a hypothetical project management SaaS application:
Decision Context: We want to analyze our product’s core task management capabilities to identify areas for improvement and potential new features to build.
Identified Potential Attributes:
- Ability to create tasks and subtasks
- Task due dates and reminders
- Commenting and file attachments on tasks
- Team collaboration and task assignment
- Integrations with communication tools
- Task visualization via Kanban boards
- Custom fields for task properties
- Workload analytics and reporting
After surveying customers about the importance and impact of each of these attributes, the Kano analysis revealed the following categorizations:
Must-Be Attributes:
- Ability to create tasks and subtasks
One-Dimensional Attributes:
- Task due dates and reminders
- Commenting and file attachments on tasks
- Team collaboration and task assignment
Attractive Attributes:
- Task visualization via Kanban boards
- Integrations with communication tools
Indifferent Attributes:
- Custom fields for task properties
Reverse Attributes:
- Workload analytics and reporting (too complex for many users)
Based on this analysis, the product team was able to formulate an optimized roadmap:
1. Foundational Priorities:
Ensure the “must-be” ability to create tasks/subtasks is solid. Enhance the “one-dimensional” attributes like due dates, commenting, and team collaboration features that directly drive user satisfaction.
2. Differentiation Opportunities:
Invest in delivering the “attractive” Kanban board visualization and communication tool integrations, which could delight users and set the product apart from competitors.
3. Areas to Simplify:
Eliminate the overly complex workload reporting capabilities that were unimportant or even off-putting to many users. Avoid investing in building out custom field capabilities for now.
By aligning their roadmap decisions to the Kano insights, the product team optimized their way of working to double down on the highest priorities, uncover innovative new capabilities to differentiate the product and strip away lower-impact or frustrating elements.
As they continue gathering user feedback over time, the team can cycle through the Kano Model process again, adjusting their product strategy based on how customer needs evolve.
Best Practices and Tips
To get the most out of the Kano Model, keep these tips and best practices in mind:
Get the Right Sample Size:
Ensure you collect survey responses from a representative and adequate sample size of your customer base to get accurate, statistically significant data. This may require incentivizing participation.
Combine With Other Data Sources:
While powerful, the Kano Model is most effective when used in conjunction with other customer insights like product usage analytics, support ticket data, user interviews, etc. Look at it as one important lens rather than the entire picture.
Involve Cross-Functional Partners:
The Kano process works best when you involve stakeholders from customer-facing roles like sales, support, and success in addition to product and engineering.
Keep An Open Mind:
Be willing to put assumptions aside and be open to surprising or unexpected findings from the Kano analysis that contradict what you thought you knew about customer preferences.
Customize the Model:
The basic Kano framework is flexible – you can tweak the categories, scales, or questions to best fit your particular product/market needs as long as you maintain consistency.
Update Regularly:
Customer needs are constantly evolving, so plan to revisit and update your Kano Model analysis on an ongoing, periodic basis rather than treating it as a one-and-done process.
Communicate Clearly:
Help your team and stakeholders understand the “why” behind the Kano Model-driven roadmap decisions so they appreciate the customer-centric approach.
Measure Impact:
Track metrics like product usage, customer satisfaction/NPS, churn reduction, and revenue impact to validate whether delivering on the Kano priorities is paying off as expected.
