The modelling process will result in an enterprise model (EM) which represents all or part of the [[enterprise operation]]. These models will allow simulation of operational alternatives and thereby their evaluation leading to the optimum structure, contents and behaviour of the enterprise operation. GERAM provides a generic description of all the elements recommended in enterprise engineering and integration.

* ''GERA--Generic Enterprise Reference Architecture'' : Defines the enterprise related generic concepts recommended for use in enterprise integration projects. These concepts include enterprise systems life cycle; business process modelling; modelling languages for different users of the architecture (business users, system designers, IT modelling specialists, others); integrated model representation in different model views.
The Generalised Enterprise Reference Architecture and Methodology (GERAM) consists of a series of eight main components, as shown in figure 1:

''Generic Enterprise Reference Architecture'' (GERA) defines the enterprise related generic concepts recommended for use in enterprise integration projects. These concepts include [[life cycle]]; enterprise [[entity type]]s, [[enterprise modelling]] with [[business process modelling]]; integrated model representation in different [[view model|model view]]s and [[modelling languages]] for different users of the [[enterprise architecture]] (business users, system designers, IT modelling specialists, among others).<ref name="Nell97"/>
