Overview
Enterprise modelling is seen as the major item in enterprise engineering and integration. Therefore, both the methodologies and the corresponding languages will be implemented in enterprise modelling tools (GEMT) which will support the enterprise integration process. Ontological theories (OT), generic enterprise models (GEMs) and generic modules (GMs) will support the modelling process by providing means for more efficient modelling.
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.
Generalised Enterprise Reference Architecture and Methodology (GERAM) is an enterprise-reference architecture that models the whole life history of an enterprise integration project from its initial concept in the eyes of the entrepreneurs who initially developed it, through its definition, functional design or specification, detailed design, physical implementation or construction, and finally operation to obsolescence. The architecture aims to be a relatively simple framework upon which all the functions and activities involved in the aforementioned phases of the life of the enterprise-integration project can be mapped. It also will permit the tools used by the investigators or practitioners at each phase to be indicated. The architecture defined will apply to projects, products, and processes; as well as to enterprises.
