A conceptual QFD planning model

Abstract

Quality function deployment (QFD) is a structured approach to seek out customers, understand their needs, and ensure that their needs are met. QFD is probably the most important management tool developed to assure quality in new or improved products and services. As with any other tool, the quantum of benefits obtained from the use of QFD is proportional to the effectiveness of its use. To enhance the effectiveness and efficiency of QFD as a means to transfer the``voice of the customer'' into design and production, a new comprehensive hierarchical framework for QFD planning process and a zero-one goal programming model for the selection of design requirements are proposed. The hierarchical framework contributes to the strategic guidance and provides clear direction for QFD teams during the construction of the house of quality. The decision model assists in determining a set of design requirements that most effectively meet customer needs subject to limited resources and other organizational restrictions. An illustrative example is also provided to demonstrate the practical usage of the design selection model.

Which Design Methodologies Are Effective to Support a Capstone Project in Aerospace Design Engineering?

“…In a general sense [32], QFD serves as a methodology to support the processes: 1) defining the decision context and the decision maker's objectives, 2) identifying/generating alternatives, 3) creating a decision model, 4) analyzing the alternatives, and 5) selecting the best alternatives. The whole QFD procedure uses a series of matrices (HOQs) to express linkages between input and outputs of different phases of development (e.g., design, manufacturing, and quality control) [34]. Although the integration of QFD and SE has been suggested in the literature, some difficulties in applying QFD exist such as 1) its popularity has not always been translated to successful practice, and 2) when applied inappropriately, it may increase work without producing any benefits [34].…”

Based on Eversheim [18], comprehensive implementations of the QFD methodology may involve processing up to 30 matrices.…”

Manufacturing Quality Function Deployment: Literature Review and Future Trends

“…Han et al [88] proposed a new comprehensive hierarchical framework for QFD planning process and a zero-one goal programming model for the selection of design requirements to enhance the effectiveness and efficiency of QFD as a means to transfer the VOC into design and production. The hierarchical framework contributes to the strategic guidance and provides clear direction for QFD teams during the construction of the HOQ.…”

Information Quality Function Deployment

“…QFD is driven by what the customer wants and not just by technological innovation and is considered as a means translating the 'voice of the customer' into specific, measurable product and process characteristics [5,12]. The matrix representing QFD is often called the 'House of Quality'.…”
