A Kano Model based Computer System for Respondents Determination: Customer needs analysis for Product Development Aspects

摘要

The first step to develop a product is to identify a set of customer needs. In this regard, Kano model is often used. Using Kano model, a product developer can identify whether or not a product attribute is attractive, must-be, or alike. To do so, it is important to obtain customers' opinions using a prescribed questionnaire. This raises a fundamental question that is how many customers should be asked to make a reliable conclusion. We have developed a system that simulates customer answers in accordance with Kano model. We have used the system to know the minimal number of customers needed to determine whether or not a product attribute is attractive, must-be, reverse, or alike. We intend to show the results related to the abovementioned issue and discuss how to integrate the system into a real-life product development process.
