The design phase is one of the crucial and important steps in the development of any product. All processes in the product life cycle are strongly determined by the product design, the concept of lean design aims to maximize customer value and minimize waste throughout the product life cycle by an optimized product design. However, and considering the complicated aspect of the design activity, a designer generating a holistic product design must take into consideration several parameters and aspects. Therefore, this paper argues for formalizing the product design methodology in a lean vision, throughout the modeling of different aspects of the product design process while integrate the lean principals, that can be exploited by company actors or software analysts. For this purpose, we used the UML modeling standard who has become an effective tool in information analysis in industrial design, we believe that such proactive collaboration between tools can significantly reduce the effort and time required for product design.
