Building information system requirements using generic structures

We present generic knowledge to speed up the construction of information system requirements and more importantly the behavioral part of entities. Our solution is based on the hypothesis that generic structures (independent of a particular application) can be associated to classes of real world phenomena. Building information system requirements using such structures means to instantiate those structures to the current context. The designer no longer has to redo the conceptualization effort, he can concentrate on the perception of the reality being described. In order to use those structures and to represent the generic knowledge, we present a design model process based on the triplet formalism <situation, decision,
