Kano model
Abstract
The Kano model is a method to scale the layers of quality and to achieve consumer satisfaction in a project or for a product. The Model was published in 1978 by Noriaki Kano (*1940), a Professor of the Tokyo University of Science. [1] The theory is proposed to understand the relationship between customer satisfaction and quantitative measures. The requirement and the performance of the product or service derive from the different types, the model provides. The model gather the needs of the customers to include them in the development of a product or service. [2] In a product development project it is recommended to use the kano model to meet customers needs and to determine requirements in an early project phase. The article provides the explanation of the kano model, the application and how to make projects successful by involving it.
