What are the differences? If they are the same thing should we merge the two articles?--GrWikiMan 16:54, 18 October 2006 (UTC)
- Enterprise architecture generally refers to a framework or methodology involving a number of different models or representations, whereas enterprise modelling refers to the representation itself. However I agree this is not clear from the articles at present. --RichardVeryard 19:04, 6 July 2007 (UTC)
Comparison of methodologies
I have removed the unsubstantiated claim that "the most effective and least time-consuming approach to Enterprise Modelling has proven to be Soft Systems Methodology". There have been some comparative reviews of methodologies, but they rarely produce such one-sided results. --RichardVeryard 10:47, 29 August 2007 (UTC)
"Enterprise modelling is the process of improving the enterprise performance through the creation of enterprise models" is a terrible definition. Someone who knows what enterprise modeling is needs to write a better definition. Defining a term using the terms being defined is a bad idea. It doesn't help out people who don't know what "enterprise modelling" is —Preceding unsigned comment added by 188.8.131.52 (talk) 07:28, 7 November 2007 (UTC)
In my opinion, this field is notable but somewhat incoherent, and this page reflects the lack of coherence.
- It cites a ragbag of techniques, with varying relevance to enterprise modelling. (For example, this page has a link to the Object-Oriented Modeling page, but this page is largely about OO programming and doesn't mention enterprise modelling at all. Of course some form of OO modelling could be used in an enterprise modelling purposes, but where is the source verifying this usage?)
- There are links to various obscure research projects.
- There is a vague mention of Mario Bunge. Now I am aware of a possible connection here, I have heard people talking about Bunge in this context, but I don't know of any verifiable source for this connection.
The main problem here is that I can't see how to make the page more coherent without doing the original research needed to make the field itself more coherent. --RichardVeryard (talk) 13:27, 6 November 2008 (UTC)
- I guess I agree on the enterprise modelling being incoherent. I think this is also true with close related fields as enterprise architecture, enterprise engineering, business process modelling, enterprise ontology, etc. But this is a general phenomenon in contemporary applied science. Now I have a few ideas about improving these articles and I hope to get to it in the weeks to come.

Hi Marcel. I appreciate the efforts you are making to improve this page. But there are still some problems with it, and I can't see how to get around these problems without doing a bit of original research. For example, I think it was you who added a link to Object-Oriented Modeling. Now I am aware of people who claim the relevance of OO modelling to enterprise modelling, but those claims are disputable and possibly even unverifiable. And if we included all the techniques for which people have made similar claims, we'd produce an extremely long list indeed. Meanwhile, the language that is possibly closest to being adopted as a standard for enterprise modelling isn't in there yet. (I guess I'd better add it myself.) --RichardVeryard (talk) 13:39, 6 November 2008 (UTC)
- Hi Richard. I gave a general respons on my talkpage. I will respond here on the specific issues:
- So far I just wikified the article. I haven't started improving this article which I will.
- I didn't add the link to Object-Oriented Modeling in the apst days, see my changes here. The link was added in 2006, see here by User:GrWikiMan.
- I am not sure about the link between enterprise modelling and object-oriented modelling. I do think the term enterprise modelling itself should be better explained.
- I understand that with "the language that is possibly closest to being adopted as a standard for enterprise modelling", you mean ArchiMate. Maybe we can improve that article some more. I can translate parts of the Dutch article here.
- I will separately respond on your "coherence" remarks.

Soft Systems Methodology section removed
I removed the following section:
- Enterprise modeling has been developed as a variant of Soft Systems Methodology by Brian Wilson. He also developed an Enterprise Model entitled Vision Realisation in support of the Office of Government Commerce's (OGC) methodology for programme management, i.e. Managing Successful Programmes (MSP) and applied his approach in a large number of public and private organisations, e.g. MoD, NHS, DWP, British Telecom, BAE Systems, Hachette Livre UK, etc.
Economic model section replaced
I replaced the following text with an introduction about economic modeling
- The modeling of the enterprise network could facilitate the creation of enhanced understanding of the business processes of the extended enterprise and relations that extend across the boundaries of the enterprise. A particularly effective form of enterprise modelling is concerned with the definition of statements of purpose and the derivation of human activity systems. In an organisational context these Human Activity Systems become conceptual Enterprise Models, whereas in a programme and project management context they are known as Programme Blueprints, each representing what needs to be done to achieve the stated purpose. Enterprise models derived in this way are useful tools for conducting organisational reviews, information analysis and business systems alignment.
Motivation and Governance in Enterprise Modeling
The current article does not make enough emphasis on the modeling of "motivation" in enterprise modeling. In Zachman Framework, this is the entire top row, called "Scope", addressing the goals of the enterprise (the "What"), the means and strategies (the "How"), the organizational structure ("Where"), the roadmap ("When") and the motivation ("Why"). This is important, because this is what constitutes the policy of the enterprise, which then provides input into the system requirements and system design.
Another important aspect of an enterprise is governance. This includes the regulations to which the enterprise has to comply; business rules of the organization and how they support the scope; certification and accreditation issues, assurance, etc.
Enterprise Architecture Framework do cover the "scope" issues.
There are several international standards that are relevant to this area, such as the ITU-T User Requirement Notation (URN), OMG Business Motivation Metamodel (BMM), the upcoming ISO 15026 related to the assurance case, etc.
- If you think the Business Motivation Model or Business motivation modeling as a subject is notable enough, you could try write an article about it first. -- Mdd (talk) 00:04, 11 March 2009 (UTC)
- It's already been deleted (in my view wrongly) so be careful. Wikipedia:Articles for deletion/Business Motivation Model --RichardVeryard (talk) 18:14, 11 March 2009 (UTC)
Focussing and expanding the article
I like to get this article more focussed, and differences with inter-related pages clearified, sucha as business process modeling, enterprise engineering, enterprise architecture and enterprise architecture framework. The article could use improvement in every section:
- The history section should be expanded.
- In the "Enterprise modeling basics" is more focussed on the building blocks of enterprise modeling techniques. If the Enterprise modelling techniques (see next step) are descriped here, maybe this section could be expended as well some more.
- In the Enterprise modelling techniques schould be expended. As a start I added the Design and Engineering Methodology for Organisations, and removed.
- An introduction of Enterprise engineering is added
- Related items have been grouped in a related field section. I think eventually this section should be reduced.
I also think this article needs an other first (introduction) image.

Enterprise Models & Methodologies listings
Ted Williams (2000) : Enterprise Models and Methodologies
Ted Williams (2000) on http://www.pera.net/ (Last updated August 18, 2000) gave an interesting listing Enterprise Models and Methodologies. He claimed it is "difficult to distinguish between Models that have associated Methodologies, and Methodologies which are based on a conceptual model".
- CARNOT - Part of Enterprise Integration Program at MCC : The Carnot Project in the Enterprise Integration Program of the Information Systems Division at MCC is addressing the problem of logically unifying physically-distributed, enterprise-wide, heterogeneous information. Source: Charles J. Petrie (1992). Enterprise integration modeling. p.300
- C4 - General Motors : ln 1989, General Motors embarked on a corporation-wide, five-year effort to transform the way it designs and produces. The GM/EDS C4 program addresses systems technology as it applies to preproduction, and provides a standard technology platform
- CPDEP - Chevron Project Development and Execution Process : This methodology was developed by Chevron to manage their internal projects. This is a project management process or a process for capital project management. The key outcomes of the project are to select the right projects by improving decision making throughout Chevron and to improve project outcomes through excellence in executing decisions.

- SEW-OSA - System Engineering Workbench centered on CIM Open System Architecture
- SSADM - Structured Systems Analysis and Design Method

Now this is a rather contrast with the current listing of Enterprise modelling techniques:
- Active Knowledge Modeling,
- Design & Engineering Methodology for Organizations (DEMO)
- Dynamic Enterprise Modeling
- Enterprise Modelling Methodology/Open Distributed Processing (EMM/ODP)
- Extended Enterprise Modeling Language
- Process modelling such as CIMOSA, DYA, IDEF3, LOVEM, PERA, etc.
- Integrated Enterprise Modeling (IEM), and
- Modelling the enterprise with multi-agent systems.
And this seems worth examing. At first site several initiatives mentioned by Williams don't classify here as enterprise modelling, such as:
- I have tried to find some more information about all these initiatives, but it seems about 8 of the 40 initiatives mentioned have gained notability. -- Mdd (talk) 19:54, 29 July 2009 (UTC)

Source: Terje Totland Enterprise Modeling as a Means to Support Human Sense-making and Communication in Organizations. Dr. ing. dissertation Norwegian University of Science and Technology at idi.ntnu.no, August 29, 1997 (content online)
In Ch 5. Contemporary Approaches to Enterprise Modeling (online) Totland gave a similar listing of contemporary approaches to Enterprise Modeling. He mentioned:
- From Fuzzy to Formal (F3) : F3 is a comprehensive framework for improving requirements acquisition and transformation into valid information systems specifications by Bubenko (1993).
- The Enterprise framework : Enterprise project is a UK initiative incorporating both academic and industrial partners. The main aim of the project is to "provide a method and computer toolset which will help capture aspects of a business and analyse these to identify and compare options for meeting the business requirements." (Fraser, 1994:3)
- Toronto Virtual Enterprise (TOVE) : The TOVE project at Enterprise Integration Lab, University of Toronto, develop a framework for enterprise integration (EI) based on enterprise modeling.
- The Caesar Framework : The CAESAR framework (Christiansen and Thomsen, 1994) was developed as a part of the CAESAR Offshore project, focusing on more cost effective development of small petroleum fields located at the Norwegian continental shelf.
- The METIS approach : METIS Solutions, a subsidiary of the NCR corporation, have a product series aimed at enterprise modeling and related activities
- Soft System Methodology (SSM) : Soft Systems Methodology is an approach to inquiry into problem situations perceived to exist in the real world (Checkland and Scholes, 1990:18).
- Object Modeling Technique (OMT) : OMT (Rumbaugh et al., 1991) was developed as an approach to software development.
- Object-Oriented role analysis and modeling (OOram) : OOram (Reenskaug, 1996) is intended to be a generic methodology for software engineering.
- Speech-Act based office Modeling aPprOach (SAMPO) : SAMPO is an approach to development of office information systems based on a language/action view of the office (Hirschheim et al., 1995:199). An office is seen as a system of communicative action (Auramäki et al., 1988:126), and an information system is considered a technical implementation of a social system.
Fraser and Tate (1995): Enterprise Ontology
Source: John Fraser and Austin Tate (1995). The Enterprise Tool Set: An Open Enterprise Architecture. AIAI, University of Edinburgh.
- Enterprise Ontology
- We have explored five areas pertinent to enterprise modelling (activity, organisation, strategy, marketing and time) and, after discussion, we have `bought in' to the definition of over 100 terms. We acknowledge the time, expertise and material of various other people and bodies who have contributed, directly or indirectly, to the development of the ontology. These contributors include:
- KSE: ARPA Knowledge Sharing Effort
- ARPI: ARPA/Rome Laboratory Planning and Scheduling Initiative
- O-Plan: O-Plan Project, University of Edinburgh
- PIF: Process Interchange Format and the Process Handbook work at MIT and the University of Hawaii
- TOVE: Toronto Virtual Enterprise Project, University of Toronto
- ORDIT: Esprit project No. 2301
- CYC: Common Sense Knowledge Base Project at MCC and Cycorp
- WfMC: Work Flow Management Coalition
- The first version of the ontology is paper based and we are now working on encoding it in KIF, the Knowledge Interchange Format developed under the Knowledge Sharing Effort. We know that the ontology will evolve as the pro ject proceeds. We envisage the Enterprise tool set providing facilities to maintain and expand the ontology
