The improvement of Kansei engineering by using the repertory grid technique

Steinberg F., Tursch P., Woll R.

Management and Production Engineering Review

2015

Vol. 6, No. 3

77--82

A customer-oriented approach to product development with particular consideration of emotions is represented by Kansei Engineering. Developed by Mitsuo Nagamachi, Kansei Engineering is characterized by the possibility to capture customer perceptions and to translate them into product features. In order to assess these perceptions, a semantic space is generated. For this purpose it is necessary to identify Kansei words that are gathered up through research in marketing concepts, scientific journals and service reports. This procedure though displays the disadvantage of not being able to identify all emotions referring to the investigated product. One way to improve the identification of Kansei words is Repertory Grid. The Repertory Grid technique makes it possible to gather unaltered perceptions through in-depth interviews from the direct interaction with customers. Thus, the interview phase of the Repertory Grid technique offers an improved approach to identify of Kansei words.

Integration of TRIZ into quality function deployment

Management and Production Engineering Review

Purpose: The objective of successful companies is the integration of customer requirements in the development process of a new product. Therefore, the Quality Function Deployment method has proven useful several times. The customer requirements often contain contradictions, which are mostly solved by compromises. The aim should be to integrate all customers’ demands and wishes into future products. Methodology: The theory of inventive problem solving can be applied to eliminate compromises in the product development. The method’s different tools enable a goal-oriented and systematic conflict resolution and may help to uncover trends. This paper displays an approach where individual tools of TRIZ are integrated into the Quality Function Deployment. Results: The result of this work is the presentation of the resulting benefits from combining the two methods. For this reason, individual tools of TRIZ are used in different points of the QFD process. The paper shows examples of starting points. Value of paper: In the context of this paper, the benefits from the interaction of QFD and TRIZ are presented. These are particularly evident in the initial phase of project implementation. In this phase the goal of the QFD process is to succeed in translating the voice of the customer for the company and then integrating it into the product development.
