The Role of Modularized QFD in an Interdisciplinary Approach for System Concept Selection


This paper discusses a role of modularized Quality Function Deployment (QFD) matrices in an interdisciplinary approach for system concepts selection. The approach uses a set of interdisciplinary tools that consists of marketing, accounting, value engineering and design engineering. When using modularized QFD matrices in the interdisciplinary approach, engineers specify target requirements before assessing how each output design requirements (e.g., system requirements) contributes to the achievement of input design requirements (e.g., customer requirements). Then engineers use their value of each output design requirement in QFD relationship matrices. By setting target requirements for each system module, engineers can freeze interactions between modules when modularizing QFD matrices. By using engineers' value in QFD relationship matrices, engineer can allocate worth of system (for the customers) to system modules based on engineers' value. The target cost of modules calculated from the allocated worth reflect both customers' and engineers' value.
