Information modeling design is the key of product development. An information modeling is discussed in this paper. It determines product function, form and basic structure. Major cost is spent in early product development. The model presented in this paper includes activity model for the process design. The activity model sets the context in which the objects are defined and used. The main purpose of the model development is to initiate standard interface specifications that are necessary for design and process development. The design information that is necessary for conceptual process planning has been collected and modeled using UML.
