Enterprise: a complex set of business processes that can be designed to accomplish a specific set of objectives.
Enterprise integration ( agile manufacturing, business process reengineering, CIM):
The coordination of the operation of all elements of the enterprise working together in order to achieve the optimal fulfillment of the mission of that enterprise as defined by enterprise management. 1
A description (often graphical) of the structure of something 1 .
A structured plan, a framework on the basis of which a product or an organization of an enterprise can be constructed 2
Developed by the laboratory for automation and production at the university of Bordeaux- France since 1970’s.
GIM is composed of the following elements:
GRAI conceptual model: a representation of basic concepts of a manufacturing system decomposed into three sub-systems: physical system, decision and information system.
GIM modeling framework (RA) with three dimensions: views, life cycle, and abstraction level.
GIM structured approach: guide to show how to perform analysis and design of the manufacturing system in three main phases: analysis, user-oriented design, and technical-oriented design.
GIM modeling formalisms (languages): GRAI grid and GRAI nets for decision system modeling, IDEF0 and stock/resource for physical system modeling, ER for information system modeling, IDEF0 for functional system modeling.

The IFAC/IFIP Task Force on Architectures for Enterprise Integration was formed by IFAC (The International Federation of Automatic Control) and IFIP (The International Federation for Information Processing) in August 1990.
The Task Force objective was to contribute a single, universally accepted architecture, framework, or model for enterprise integration.
They developed the architectural specification GERAM (Generalized Enterprise Reference Architecture and Methodology).
Task Force recognized three RA:
The "matrix" model for GERAM was developed by combining the distinctive characteristics of each of three studied architectures into one diagram.
