D***esign-for-X (DfX) approaches are of great importance to support sustainable development of new products, since the goal of DfX practices is to improve life cycle cost, life cycle environmental performance, increase design flexibility, manufacturing efficiency, etc. Therefore DfX supports a better decision-making process whenever a new complex product is being developed. In this work the new Lean Design-for-X (LD f X) approach is presented embracing the principles of Lean Product Development and Modular Design, for a systematic applicability by design engineers and product managers, assessing the effectiveness and efficiency of a given product design. An LD f X index metric, ranging between 0-100%, and original scorecard were created for consistent decision support for the comparison of different design concepts or products, integrating different “X” domains. The approach was applied in a real design study of a machine tool (press-brake), integrating Ecodesign principles, Design for Structural Optimization and Modular Design.
