Recent literature in Systems Engineering has suggested the use of “value” to drive decision-making activities during preliminary design. Here the choice of a technology for a system/component is often oriented by the outcomes of a value analysis. However, to correctly evaluate design trade-offs, a visual link has to be established between these results and the product requirements/geometry. The paper proposes the use of color-coded 3D CAD models to support the visualization of value analysis results in a Stage-Gate® process. The approach has been developed and exemplified within a case study related to the design of an aero-engine component, and has been demonstrated using SIEMENS NX HD3D Visual Reporting. Eventually, the paper presents the results of verification activities conducted in academia.
