A draft integration of information models: Complement model and Oliver model

This paper attempts to reconcile and extend two information models that have been developed independently to describe information capture in systems engineering activities. An internationally accepted information model is a major step toward understanding different methodologies in use in different organizations. It can provide a basis for integration of tools that support the several methodologies. The information model describes the static structure of the information used in the systems engineering steps. The information model is structured so that it maps readily to a process model which describes systems engineering behavior: the engineering steps, input and output of the steps, and the sequences, concurrencies, and branches among the steps
