GRAI method

Last updated

The GRAI method, GRAI is short for Graphs with Results and Actions Inter-related, and the further developed GRAI Integrated Methodology (GIM) [1] is a modeling method of Enterprise modelling.

Contents

The GRAI method was first proposed by Guy Doumeingts in his 1984 PhD thesis, entitled La Méthode GRAI, [2] further developed at the GRAI/LAP (Laboratory of Automation and Productics) of University Bordeaux, [3] and followed by GRAI/GIM by Doumeingts and others in 1992. [4]

The GRAI method can represent and analyze the operation of all or part of a production activity. The strength of the GRAI method lies in its ability to provide modelers can effectively model the decision-making system of the company, i.e. organizational processes that generate decisions.

In the GRAI methodology four types of views had been incorporated: the functional view, physical view, decisional view and informational systems view. [5]

IDEF, initially an abbreviation of ICAM Definition and renamed in 1999 as Integration Definition, is a family of modeling languages in the field of systems and software engineering. They cover a wide range of uses from functional modeling to data, simulation, object-oriented analysis and design, and knowledge acquisition. These definition languages were developed under funding from U.S. Air Force and, although still most commonly used by them and other military and United States Department of Defense (DoD) agencies, are in the public domain.

CIMOSA, standing for "Computer Integrated Manufacturing Open System Architecture", is an enterprise modeling framework, which aims to support the enterprise integration of machines, computers and people. The framework is based on the system life cycle concept, and offers a modelling language, methodology and supporting technology to support these goals.

A functional software architecture (FSA) is an architectural model that identifies enterprise functions, interactions and corresponding IT needs. These functions can be used as a reference by different domain experts to develop IT-systems as part of a co-operative information-driven enterprise. In this way, both software engineers and enterprise architects can create an information-driven, integrated organizational environment.

<span class="mw-page-title-main">Metamodeling</span> Concept of software engineering

A metamodel is a model of a model, and metamodeling is the process of generating such metamodels. Thus metamodeling or meta-modeling is the analysis, construction, and development of the frames, rules, constraints, models, and theories applicable and useful for modeling a predefined class of problems. As its name implies, this concept applies the notions of meta- and modeling in software engineering and systems engineering. Metamodels are of many types and have diverse applications.

Several methods have been created to define an assessment process for free/open-source software. Some focus on some aspects like the maturity, the durability and the strategy of the organisation around the open-source project itself. Other methodologies add functional aspects to the assessment process.

<span class="mw-page-title-main">Enterprise modelling</span>

Enterprise modelling is the abstract representation, description and definition of the structure, processes, information and resources of an identifiable business, government body, or other large organization.

Enterprise engineering is the body of knowledge, principles, and practices used to design all or part of an enterprise. An enterprise is a complex socio-technical system that comprises people, information, and technology that interact with each other and their environment in support of a common mission. One definition is: "an enterprise life-cycle oriented discipline for the identification, design, and implementation of enterprises and their continuous evolution", supported by enterprise modelling. The discipline examines each aspect of the enterprise, including business processes, information flows, material flows, and organizational structure. Enterprise engineering may focus on the design of the enterprise as a whole, or on the design and integration of certain business components.

The history of business architecture has its origins in the 1980s. In the next decades business architecture has developed into a discipline of "cross-organizational design of the business as a whole" closely related to enterprise architecture. The concept of business architecture has been proposed as a blueprint of the enterprise, as a business strategy, and also as the representation of a business design.
