The Product Development Process (PDP) multidisciplinary characteristic, into a Concurrent Engineering (CE) environment, where several systems, methods and tools are used, means that the information flow on PDP becomes complex. There are approaches, even as Product Lifecycle Management (PLM), and support tolls (e.g. CAD; CAE; CAM), but there is no a common language for all PDP components, arise multiple interpretations about information, prejudicing product results. This scenario highlights the requirements dynamism along the PDP stages. These are given from the customer needs, increasing its detail level through the process evolution. Generally, enterprises treat the requirements through standalone stages at the PDP start, but not consider the requirements interactions and its impacts about the all products systems components. In this context, the Model-based System Engineering (MbSE) approach proposes a product representation structure, through a unique and atemporal model, which assumes the role of a PDP guide, being the unique information source to stakeholders. This model is able to represent all components, system and subsystems interactions. Last years, several enterprises has used the language System Modeling Language (SysML) for modeling complex systems, achieving good results. In this sense, the goal of this work is propose a model that allows a loyal product representation, able to help the requirements definition and management along the PDP. This model allow the product information access, usage and traceability at various abstraction levels, by all stakeholders. The execution of the methodological procedures is based on the DSR approach. This approach consists of problem identification, goal setting, solution development, evaluation and reporting of results. The research is applied in the context of a global manufacturer of agricultural machinery, especially a tractor PDP. The product is represented through a system model using the SysML language. The modeling and product information is demonstrated and evaluated according to the DSR criteria. Using the model, is possible to identify the impact of the requirements on the different components of the product, as well as the interrelationships present in the system. In addition, it is possible to access the model information by different stakeholders, demonstrating its use with CAD tools and Requirements Management.
