ISO 19439

ISO 19439 is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand ISO 19439 rather than just read about it. In short: ISO 19439:2006 Enterprise integration—Framework for enterprise modelling, is an international standard for enterprise modelling and enterprise integration developed by the International Organization for Standardization, based on CIMOSA and GERAM.

Key takeaways

ISO 19439 belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect ISO 19439 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of ISO 19439 from memory before moving on to harder problems.

Reference excerpt

ISO 19439:2006 Enterprise integration—Framework for enterprise modelling, is an international standard for enterprise modelling and enterprise integration developed by the International Organization for Standardization, based on CIMOSA and GERAM.

Overview ISO 19439 framework wants to provide a "unified conceptual basis for model-based enterprise engineering that enables consistency, convergence and interoperability of the various modelling methodologies and supporting tools. The framework does not encompass methodological processes; it is neutral in this regard". This standard specifies a framework, which "serves as a common basis to identify and coordinate standards development for modelling of enterprises, but not restricted to, computer integrated manufacturing. It also serves as the basis for further standards for the development of models that will be computer-enactable and enable business process model-based decision support leading to model-based operation, monitoring and control".

Dimensions According to David Shorter (2004) the ISO19439 is alike CIMOSA, and has defines three dimensions for enterprise modelling:

Model phase : "The enterprise model phases are based on the idea that enterprise models have a life cycle that is related to the life cycle of the entity being modeled. The phases defined in the standard are: Domain Identification, Concept Definition, Requirements Definition, Design Specification, Implementation Description, Domain Operation, Decommission Definition." View dimension : "This is based on the idea that both enterprise modelers and users filter their observations of the real world by particular views. The predefined views are: Function View, Information View, Resource View, Organization View/Decision View." Genericity dimension: "This defines the dimension from general concepts to particular models . The standard defines three levels of genericity: Generic Level, Partial Level, Particular Level"

Worked examples

Example 1 — a first encounter with ISO 19439

Start with the simplest possible case. Write down what ISO 19439 claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to ISO 19439 before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about ISO 19439 ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of ISO 19439

In research: ISO 19439 appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses ISO 19439 in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: ISO 19439 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Enterprise modelling, ISO standards, Modeling languages, so understanding it makes those chapters shorter.
In everyday life: Look for ISO 19439 outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is ISO 19439 in simple terms?

Why does ISO 19439 matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study ISO 19439?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
