Study Notes
- The Kano model, developed in 1984 by Noriaki Kano, is used to analyze customer needs and determine new product requirements.
- The Kano model categorizes customer requirements into five categories: basic needs, performance needs, excitement needs, indifferent needs, and reverse performance needs.
- Basic needs are must-haves that when not present or executed well, lead to dissatisfaction.
- Performance needs are where more is better, and the better they are executed, the higher the satisfaction level.
- Excitement needs are the delighters of a product design, leading to extremely high satisfaction levels when present.
- The Kano questionnaire involves asking functional and dysfunctional questions for each feature to determine customer responses and classify features into the five categories.
- The Product Design Specification (PDS) is an exact statement of what the product must do and what the customer design requirements are, serving as the foundation for the design process.
- The PDS should contain all facts identified in market research, realistic design constraints and targets, and clear, specific product requirements to guide the design process effectively.
