Using product design methods in designing and validating entreprise models

In our research, the enterprise is considered as a system evolving in an environment (the market, the concurrences, suppliers, humanity) with given objectives, generating certain values, that carries out an activity (a set of processes) and sees its internal structure evaluating without loosing its unique identity. To handle the complexity, the ever-changing state of this particular system many models are proposed. The profusion of enterprise models makes it confusing to understand and use them. But as enterprises continue their evolution, we will be building new models to fit new enterprise needs. But models design is rarely discussed. Besides, it is already difficult to choose between different existing models. Studying models' validation can give us some criteria to assume that a model is more efficient and though will be better used. In this paper, we, first, draw a state of the art of enterprise models that will justify our focus on some enterprise models. Second we present a design method to guide the building of selected enterprise models. The proposed design method is made clear by its application to a selected model. Third, we are proposing to validate the model through the functions it is fulfilling for the enterprise. And finally we present the perspective for our research.
