—Success in engineering activities mostly depends on success in transfer of human intent into product. Recently, product development applies product model as medium to describe product information in product data base. While modeling gives a great chance for the description of engineer’s intent, current information based product models are not capable of this description. Human intent remains in the mind of engineers and its description in interrelated data of engineering objects is still at a shallow level. Because the main barrier is information based nature of current product models, the authors propose a method to extend this product model to the background of modeled object information to include human intent. Called as information content based modeling, this new product modeling method is developed starting from modeled intent of engineers and other influencing people. Definition of information in the product model is controlled by human intent and other information content entities that are also defined by using of model of human intent. This paper concentrates on definition of human control on product model information, modeling of human intent, human intent based definition of information content and some implementation issues.
