Product development is often a balancing act. You have limited resources and time, yet the list of potential features for your product seems endless. How do you decide which features will truly delight your customers and which ones they will barely notice? This is a challenge every product manager faces. Without a structured approach, you risk wasting effort on updates that don’t move the needle or, worse, ignoring the basics that users expect as a standard.
This is where the Kano Model becomes an essential tool. It offers a clear framework for categorising features based on how they impact customer satisfaction. Instead of guessing what users want, you can use this model to make informed decisions that align development efforts with customer needs. By understanding the different ways features influence perception, you can build products that not only function well but also create genuine excitement.
What is the Kano Model?
The Kano Model is a theory for product development and customer satisfaction developed in the 1980s by Professor Noriaki Kano. At its core, the model challenges the idea that customer satisfaction is a simple linear scale where “more is better.”
Traditional thinking might suggest that if you improve a feature, satisfaction goes up proportionally. However, the Kano Model posits that not all features are created equal. Some attributes are taken for granted, while others can surprise and delight users even if they aren’t fully polished. The model classifies customer preferences into five distinct categories, helping teams visualise how different attributes contribute to the overall user experience. This perspective shifts the focus from simply adding more features to adding the right features.
Kano Model Categories
To use the model effectively, you must understand the five categories of product attributes. These categories explain how the presence (or absence) of a feature affects customer satisfaction.
Must-be Attributes are the basic expectations. These are the features that customers assume will be there. If your phone cannot make calls, you are dissatisfied. However, if the calling feature works perfectly, you aren’t necessarily thrilled; you are just neutral. These are the non-negotiables for entry into the market.
One-Dimensional Attributes follow a linear relationship. The better the functionality, the happier the customer. For example, battery life in a smartphone falls here. A longer battery life leads to higher satisfaction, while poor battery life leads to dissatisfaction. These are typically the areas where companies compete directly on performance.
Attractive Attributes are the delighters. These are features users did not expect but love when they find them. If an Attractive attribute is missing, the customer doesn’t mind because they didn’t know they needed it. But if it is present, satisfaction skyrockets. These features often differentiate a product from its competitors.
Indifferent Attributes are features that the customer simply does not care about. Whether the feature is present or absent, it makes no difference to their satisfaction levels. Identifying these is crucial so you can avoid wasting resources on them.
Reverse Attributes are features that actually cause dissatisfaction when present and satisfaction when absent. For example, some users might find high-tech security features overly complicated and frustrating, preferring a simpler interface instead.
Prioritising for Success
The Kano Model provides a sophisticated lens through which to view feature prioritisation. It moves beyond gut feelings and internal politics, grounding decisions in actual customer sentiment. By distinguishing between what users expect, what they want, and what will delight them, product managers can craft strategies that satisfy current needs while building excitement for the future. Using this model helps you deliver products that resonate deeply with your audience, ensuring long-term loyalty and market success.
