8 What is an Architecture? Architectures describe Structures their Components and their relationships... and have three purposes* Durability (firmitas) Usefulness (utilitas) Beauty (venustas) * Source: Vitruvius, De Architectura, ( The Ten Books on Architecture ), 1st Century B.C. 13

9 Architectures are needed in town planning and urban design To shape the Buildings To shape the connectivity To manage the underlying infrastructure 14

10 and this is very similar to IT landscapes in (Central) Banks To shape the Applications Domains To shape the connectivity To shape the underlying infrastructure Make ESCB Information Systems fit in the overall ESCB IT Architecture Landscape It s about horizontal & vertical Integration: ESCB-ESCB ESCB-Domestic Enterprise Content Management Analysis & Insight Execution & Monitoring Enterprise Support Processes Shared Services 15

11 ESCB IT Architecture A Policy A Blueprint A Process IT Architecture Governance Policy ESCB Reference Architecture Architecture Development Methodology (ADM)

12 ESCB IT Architecture v1.0 sets key directions in line with ESCB Architecture Drivers First Core Building Blocks for enabling Pooling & Consolidation Promotes Re-use & Loose-coupling Defines components, service components and their anatomy and design principles Defines standard service interfaces Facilitates Integration Maximizes User Efficiency Ensures Security is taken into account Principles rather than rules One for Some One for All Some for Some Some for All Integration Consolidation Loose Coupling Distributed environment Synergie Security 17

31 Agenda Introductie ESCB ArchiMate Lessons learned Q&a 36

32 Lessons learned en ervaringen Learning by doing Learning by example Medewerkers met UML-achtergrond kijken anders aan tegen modelleren met ArchiMate Enterprise Architecture is geen construction! Vermijd het modeleren van specifieke instances Goede discussies over bijvoorbeeld het gebruik van functions en services op business en applicatie laag Toegevoegde waarde van uniforme modellen in onder meer frame (~Project Start Architectuur) onderkend Noodzaak tot harmoniseren van tooling en gezamenlijke ESCB-repository onderkend 37

33 Aanbevelingen Zorg voor beschikbaarheid van enkele ervaren krachten die fungeren als coach Start small, scale fast Passeer niet de grens van constructie Voorkom het beeld van solution in search of a problem : modelleer daar waar het toegevoegde waarde heeft: beschrijving, analyse en communicatie 38
