Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO
member bodies). The work of preparing International Standards is normally carried out through ISO technical
committees. Each member body interested in a subject for which a technical committee has been established has
the right to be represented on that committee. International organizations, governmental and non-governmental, in
liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.
International Standard ISO 14258 was prepared by Technical Committee ISO/TC 184, Industrial automation
systems and integration, Subcommittee SC 5, Architecture and communications.
Annex A of this International Standard is for information only.

Introduction
The major objective of this International Standard is to define concepts and rules for enterprise models (see
clause 3) with the intent to guide and constrain other standards or implementations that do or will exist on the topic.
It accomplishes this by defining the elements to use when producing an enterprise model (see 3.2), concepts for
life-cycle phases (see 3.3), and how these models describe hierarchy (see 3.4), structure (see 3.5), and behavior
(see 3.6). This International Standard provides guidelines and constraints for enterprise models to anyone
attempting to model an enterprise or to model processes (see 3.7).
The users of this International Standard are primarily the standards bodies making more detailed standards about a
part of the integration and modeling domain. Systems implementers may also find value in the structure developed
in this International Standard so that their developments parallel the concepts outlined herein. If conforming
implementation designs have the same technology areas and nomenclature, or are able to map to them readily, the
information of one enterprise or process can be more readily shared with information of another enterprise or
process (see 3.8).
The rationale for this International Standard is that other well-designed standards in the domain of enterprise
integration and modeling are needed to provide a known environment to enterprise designers. Thus, the risk of
investing in islands of integration can be significantly reduced. Where an island does exist, then these standards
assist the designer to create the translation required for the island to interact with the known environment. A
standard for enterprise models should enhance interoperability by establishing the elements that must be present in
an enterprise model. These elements will come into play when there is need for one process to communicate with
another.

INTERNATIONAL STANDARD ISO ISO 14258:1998(E)
Industrial automation systems — Concepts and rules for
enterprise models
1 Scope
This International Standard specifies concepts and rules for computer-understandable models of a manufacturing
enterprise to better enable enterprise processes to interoperate.
This International Standard does not define standard enterprise processes, standard enterprises, standard
organizational structures, or standard enterprise data. In addition, this International Standard does not specify the
enterprise-modeling process, but forms the basis by which enterprise-modeling standards can be developed where
they are needed.
2 Definitions
For the purposes of this International Standard, the following terms and definitions apply.
2.1 Definitions of enterprise concepts
2.1.1
enterprise
a group of organizations sharing a set of goals and objectives to offer products, services or both
2.1.2
environment
the uncontrollable part of a system which is widened to the extent that a decision-taking procedure cannot be
conceived for the control of such a system
2.1.3
factors of production
that which is required to transform, transport, store, and verify raw materials, parts, (sub-) assemblies, and end
products
2.1.4
user of standard
one who applies the requirements of this International Standard for whatever purpose
EXAMPLE 1 Enterprise planners, builders, modifiers, and analyzers using the requirements to check completeness of their
activity.
EXAMPLE 2 Enterprise-model builders using the requirements to assure consistency between models to enable model
interoperability.
EXAMPLE 3 Developers of standards for enterprise representation using the requirements to assure consistency between
their standards and this International Standard.

2.2 Definitions of model concepts
2.2.1
abstraction
a shortening in duration or extent with no sacrifice of sense, used to differentiate between a real-world system and a
model of the real world
2.2.2
behavior
how an element acts and reacts
2.2.3
constraint
restrictions and limitations on the system which can come from inside or outside the system under consideration
2.2.4
element
a basic system part that has the characteristics of state, behavior, and identification
2.2.5
enterprise model
a representation of what an enterprise intends to accomplish, how it operates and possibly how it is organized,
which is used to improve the effectiveness and efficiency of the enterprise
NOTE – An enterprise model is an abstraction that represents the basic elements of an enterprise and their decomposition to
any necessary degree. It also specifies the information requirements of these elements, and provides the information needed
to define the requirements for integrated information systems.
2.2.6
model
a representation of something else expressed in mathematics, symbols, or words
NOTE – A model is an abstraction that represents one's understanding of a system or situation, and of the relevant elements
and relationships. It represents the system elements and the connectivity between the elements.
