'''Generalised Enterprise Reference Architecture and Methodology''' (GERAM) is a generalised [[Enterprise Architecture framework]] for [[enterprise integration]] and [[business process]] [[engineering]]. It identifies the set of components recommended for use in [[enterprise engineering]].<ref name="Nell97"> [[J.G. Nell]], NIST (1997).

This framework is developed in the 1990s by an [[International Federation of Automatic Control|IFAC]]/[[International Federation of Information Processing|IFIP]] Task Force on [[Enterprise Architecture|Architectures]] for [[Enterprise Integration]]. The development startingstarted with the evaluation of then existing frameworks for [[Enterprise application integration|enterprise integration]], which was developed into an overall definition of a socalledso-called "generalised architecture", which was named GERAM for "Generalised Enterprise Reference Architecture and Methodology".<ref name="BN94"> [[P. Bernus]], and L. Nemes (1994). "A Framework to Define a Generic Enterprise Reference Architecture and Methodology".

== Overview ==
One of the basics of GERAM is that [[Enterpriseenterprise modelling]] iswas seen as the major itemissue in [[enterprise engineering]] and integration. ThereforeIt contained several of building blocks, bothin which the methodologies and the corresponding languages willhave bebeen implemented, insuch enterpriseas:
* Enterprise modelling tools (GEMT) which willto support the enterprise integration process.
* Ontological theories (OT),
* genericGeneric enterprise models (GEMs) and generic
* Generic modules (GMs) will
The building blocks where designed to support the modelling process by providing means for more efficient modelling.<ref name="Nell97"/>
 
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.
