2. 2 © 2005-2006 The ATHENA Consortium. Module 2 - What are the current methods and Tools for EM? Module Structure: 1.Enterprise Frameworks 2.Standards 3.Enterprise Modelling Languages 4.Languages for Model Interchange 5.Enterprise Knowledge Spaces 6.Methodologies 7.Modelling Platforms, Infrastructures and Tools 8.Execution Platforms, Infrastructures and Tools

3. 3 © 2005-2006 The ATHENA Consortium. Enterprises Frameworks are fundamental structures which allows defining the main sets of concepts to model and to build an enterprise. Examples are: ZACHMAN GERAM GRAI ARIS CIMOSA DoDAF TOGAF TEAF AKM ISO 15745 MISSION Enterprise Frameworks

4. 4 © 2005-2006 The ATHENA Consortium. Architectural frameworks mentioned are designed to define views of specific enterprise domains. Frameworks lack capabilities for: meta-data management role-driven viewing integration with platforms model-driven design generation of interoperable solutions. Enterprise Frameworks (2)

5. 5 © 2005-2006 The ATHENA Consortium. Industrial initiatives or not- for-profit organisations working on De facto standards are: BPMI WfMC OAGIS GIS OASIS BPEL OASIS BCM UN/CEFACT BCF Rosetta Net W3C OMG Industry Initiatives, Standardisation Bodies and Organisations

6. 6 © 2005-2006 The ATHENA Consortium. European and international standards relevant to enterprise interoperability are: EN/ISO 19439: Framework for enterprise modelling EN/ISO 19400: Constructs for enterprise modelling CEN TS 14818: Decisional reference model ISO CD 18629: PSL ISO 15704: Requirements for enterprise architectures and methodologies ISO 14258: Concepts and Rules for Enterprise Models ISO/IEC 15414: Open Distributed Processing – Reference Model Standards

7. 7 © 2005-2006 The ATHENA Consortium. Enterprise Modelling Languages (EMLs) should allow building the model of an enterprise according to various points of view such as: function, process decision, economic, etc. in an integrated way. Enterprise Modelling Languages

8. 8 © 2005-2006 The ATHENA Consortium. There are two categories of languages: WPDL XPDL BPML EDOC UML profile for EAI ebXML BPDM EPC IEM Metis ITM Metis BPM Metis UML MEML Petri Nets CIMOSA GRAI IDEF PSL Languages defined at high level of abstraction as Constructs for EM (for example GRAI) which are independent of the technology of implementation Languages more related to a specific technology such as INTERNET technology based languages (for example ebXML). Enterprise Modelling Languages (2)

9. 9 © 2005-2006 The ATHENA Consortium. The languages for model exchange analysed are considered not complete enough to fully support the exchange of enterprise models defined in different modelling languages without the loss of information. PIF UEML BMT Languages for Model Interchange

10. 10 © 2005-2006 The ATHENA Consortium. Enterprise Knowledge Spaces (EKSs) are externalised knowledge spaces of four or more knowledge dimensions that contain mutual and complex dependencies of domains and elements in the four dimensions. Enterprise Knowledge Spaces

11. 11 © 2005-2006 The ATHENA Consortium. Reference models provide enterprises with an initial engineering solution, letting them determine the degree of detail of the model. Adapted to company-specific requirements, reference models evolve into company- specific models. Relevant Reference models are: Reference Model Order Throughput Reference Modelling Methodology with ARIS Methodologies: Enterprise Engineering using Reference Models

12. 12 © 2005-2006 The ATHENA Consortium. Business Process Reengineering is the activity by which an enterprise reexamines its goals and how it achieves them, followed by a disciplined approach of business process redesign. Methodologies: Business Process Reengineering

13. 13 © 2005-2006 The ATHENA Consortium. Following the User Enabling Modelling Methodology the members of the organisation learn the usage of modelling for their own work. A pilot project plays a major role to train the users. The training within the organisation is based on a “snow ball principle” to reduce the necessary training effort. User Enabling Modelling Methodology

14. 14 © 2005-2006 The ATHENA Consortium. Capability and maturity models allow a company to assess and improve its capacity in a certain field. Examples are: CMMI - Capability Maturity Model Integration EMM@ - E-Business Maturity Model ACMM - IT Architecture Capability Maturity Model Methodologies: Capability and Maturity Models

15. 15 © 2005-2006 The ATHENA Consortium. Methodologies mentioned are designed to fit the requirements of specific tool suppliers in establishing and marketing their Enterprise Modelling products. Methodologies to be developed in the future must be generic enough to be independent of the modelling languages and enterprise architecture methodologies being offered. Conclusions on Methodologies

16. 16 © 2005-2006 The ATHENA Consortium. EM platforms, tools and infrastructures are based on proprietary architectures, templates, interfaces and formats. ATHENA project is developing a common integrated modelling and execution platform: the MPCE (Modelling Platform for Collaborative Enterprises). MO²GO GraiTools Metis Enterprise ARIS for SAP NetWeaver Modelling Platforms, Infrastructures and Tools

17. 17 © 2005-2006 The ATHENA Consortium. Model activation involves actors interpreting the model and adjusting their behaviour accordingly. By updating such a model, users can adapt the system to fit their local plans, preferences and terminology. This concurrent activation and articulation (modelling) is depicted in the figure.

18. 18 © 2005-2006 The ATHENA Consortium. Workflow Management Systems (WMS) Workflow is defined as "the automation of a business process, in whole or part, during which documents information or tasks are passed from one participant to another for action according to a set of procedural rules". Industrial Solutions to Enterprise Model Execution

19. 19 © 2005-2006 The ATHENA Consortium. The Modelling Platform for Collaborative Enterprises (MPCE) will support distributed modelling and model generated workplaces. New research topic for the workflow community are: user involvement to simplify the languages and mechanisms of the Workflow Management Systems integrating support for manual interpretation Conclusions on Execution Platforms, Infrastructures and Tools
