Kano Analysis

Introduction: Kano Analysis – Understanding Customer Satisfaction

Kano Analysis is a customer satisfaction model developed by Japanese professor Noriaki Kano in the 1980s. It helps organisations classify product or service features into categories that explain how they influence customer satisfaction. By understanding these categories, businesses can prioritise which features to focus on in product development and service design.

Background

The model highlights that not all features contribute equally to satisfaction. Some are simply expected, while others can delight customers and create competitive advantage. Kano Analysis is widely applied in quality management, Lean, Six Sigma, and product innovation.

Key Elements

1. Basic Features (Must-Be / Dissatisfiers):
   • Essential attributes customers take for granted.
   • Their absence creates dissatisfaction, but their presence does not increase satisfaction.
   • Example: A hotel room must be clean and safe.
2. Performance Features (One-Dimensional / Satisfiers):
   • Directly linked to satisfaction: the better they perform, the more satisfied customers become.
   • Example: Longer battery life in a smartphone.
3. Attractive Features (Delighters / Exciters):
   • Unexpected extras that create delight when present.
   • Their absence does not cause dissatisfaction.
   • Example: A surprise free upgrade to first class.

Applications

• Data Collection: Surveys ask customers how they feel if a feature is present and how they feel if it is absent.
• Analysis: Responses classify features into categories.
• Decision-Making: Teams prioritise improving must-be features, optimising performance features, and adding delighters.
• Continuous Review: Regular updates ensure alignment with evolving customer expectations.

Relevance/Impact

Kano Analysis supports targeted innovation, resource efficiency, and a stronger customer focus. By balancing essentials with differentiating features, organisations can improve loyalty, stand out in competitive markets, and foster long-term growth.
