The design of mechanical systems, due to their multi-disciplinary and technological aspects, involves different people who, together, work and make decisions and jointly participate in the development of the product. They work in a collaborative manner; however, they may have different strategies, geographical positions, cultures and do not know the other members of the team. Preliminary design represents the early stages of the design cycle or product definition. A number of uncertainties regarding the parameters and product information are very important. There is an important lack of knowledge at this stage of the design process that must be managed or filled in order to improve and support the decision making in the early phases. It is this lack of knowledge that I propose to qualify and characterise, providing an answer to the question: how does one to take into account the lack of knowledge in decision making during the preliminary design collaboration? To do so, we propose a meta-model for structuring product information and knowledge by integrating product maturity. A metric allows this maturity to be defined, to identify the level of knowledge of the product designers and to guide the decision making, thanks to the use of a qualitative and quantitative approach. Finally, we evaluate the ability of the meta-model to generate the different models produced and its relevance to the implementation in an industrial case.
