A Tool Integration Workbench for Enterprise Architecture Marc Lankhorst Open Group APC Conference Brussels, April 22, 2004

The ArchiMate project 2½ years, July December 2004 approx. 35 man-years, 4 million euro Consortium of Dutch companies and research institutes Telematica Instituut leads the project Ideas also originated from Ordina ABN AMRO, Dutch Tax Administration, ABP pension fund Nijmegen University, CWI, Leiden University

ArchiMate goals To describe architectures and their relations Communicate architectures with all stakeholders Judge the impact of changes Realise architecture by relating to existing standards, techniques and tools

Analysis ArchiMate focus Integration Visualisation

Enterprise architecture: describing coherence Process architecture Application architecture Technical architecture Information architecture Product architecture ? ? ? ? ?

Current situation Large number of domain-specific modelling languages and tools in use (e.g. UML, workflow, BPMN, …) Modelling languages not compatible: no relations between models from different domains Modelling tools hardly integrated Small number of tools available for enterprise architecture Tools for enterprise architecture do not integrate well with existing languages and tools

ArchiMate Workbench goals A single infrastructure for creating multiple cross- domain views on an enterprise architecture by integrating existing domain-specific models into the enterprise-level abstraction level views models

Approach Starting point: reuse of existing models Model integration: define relations between models in domain-specific languages, using the ArchiMate enterprise modelling language as an “umbrella” Tool integration: develop a tool integration environment to link existing modelling tools

Model integration example Claims administration service Customer administration service Risk assessment service Payment service External application services Valuation Acceptance Registration Payment Formal claim Policy (contract) Claims administration Customer administration Risk assessment Financial application Central administration Registration Acceptance Valuation Payment Damage claiming process adapter Claims administration Customer adminstration Risk assessment Financial application Claim information service Application components and internal services adapter

Model integration options Direct relations: Via intermediate language:

Model integration architecture Tool/language-specific version of ArchiMate language

Tool integration options Direct: Tool bus:

Tool integration architecture

Use of the Workbench 1.Select your viewpoint 2.Load domain-specific models 3.Integrate these models using ArchiMate concepts and relations 4.Open object in domain-specific tool 5.Refine object in domain-specific language

Load domain-specific model

What’s next? Integration of ArchiMate with other languages and tools Using a MOF-repository for both the domain-specific models and the ArchiMate models Development of an analysis prototype Bringing together all prototypes in one environment ArchiMate as a ‘top level’ for the Model Driven Architecture

Tool architecture

Introduction & adoption Validation in practice with ArchiMate business partners Contacts with tool vendors on implementation in commercial tools IBM Rational, Select, Popkin, BiZZdesign, ASG, Adaptive Contacts with standardisation bodies Open Group OMG
