The house of quality (HOQ), which serves as the initial matrix in quality function deployment (QFD), is widely employed to set the technical objectives for engineering characteristics. Nevertheless, there exist methodological deficiencies within the HOQ, concerning the assessment of relationship ratings between customer requirements and engineering characteristics, as well as the lack of a structured process for determining design specifications. Therefore, this study proposes a formal HOQ procedure to determine the technical targets of engineering characteristics. The swing method and a specific normalization technique are utilized to incorporate correlations between engineering characteristics, aiming to improve relationship ratings. Additionally, an optimization model has been devised to maximize customer satisfaction within the constraints of available organizational resources. The procedure is illustrated using a wooden dining chair design as an example. © 2024 The authors.
