A Systematic Method for Generating EC Candidates in QFD

품질기능전개에서 체계적인 설계특성후보 도출 방법 제안

Although it is not easy to generate EC's (Engineering Characteristics), there have been few studies so far. In this paper, a systematic method for generating EC candidates is proposed. This method use the concept of 'attribute listing'. In the proposed method, customer attributes are divided into their objects and issues. And attributes from their objects and issues are generated by help of guidelines proposed, respectively. Then, measurable metrics are attained from those attributes. Finally, the metrics result in EC candidates by consistency and redundancy check. This paper gives an illustrative example for easy comprehension of the proposed method.
