Architecture definiton The Architecture (of a system) is the fundamental organization of that system embodied in its components, their relationships to each other, and to the environment, and the principles guiding its design and evolution. ISO/IEC 42010:2007 More simply put: structure with a vision 8
- 9. Enterprise Architecture EA is a conceptual tool that helps organizations get a deeper understanding of their own structure and of the way they work. It provides a map of the enterprise and it is a “route planner” for business and technology change. Important uses of it are in systematic IT planning/ architecting and in enhanced analysis and support for decision-making. handbook enterprise architecture, BiZZdesign, 2012 9

- 18. Implications • Rule #1 for EA: focus on adding value • Rule #2 for EA: be prepared • Fact: not following #1 and #2 will crush your reputation • Corollary: work with the business, not for the business 18

- 20. Where to start, what to do • Establish an AB with business executives that sets goals and KPI’s for the architecture capability. Be accountable! Aim • Make sure the goals for EA align with corporate goals and embed in e.g. project management, governance etc. • Build a mixed team in terms of background (business / Establish IT), experience (senior / junior) and focus (strategy / execution) • Plan to get your hands dirty! • The proof of the pudding is in the eating: focus on execution • Mind your communication and balance principles, models, and Execute other visuals • Claim your successes, and grow the EA practice 20
- 21. Setting • IT department of a large telecom organization in North America • TOGAF’s ADM is to support the solution process • The solution process is mostly based on waterfall principles • Key question: how do we add value to this process with TOGAF? 21

- 23. … and at the same time … While designing the “service oriented engagement model”: • We worked with the team to specify what type of models would best support the organization I with respect to each of the services • These functional questions were translated to ArchiMate models (viewpoints) • A customized metamodel was built, tailored to the specific needs of this organization 23
- 24. Setting • Large (Dutch) organization in the social security sector • A few years ago: on the verge of large enterprise transformation • Use ArchiMate to investigate the impact of this transformation • Challenge: simplify the metamodel for use in the architecture team and improve enterprise-wide communication about architecture 24

Added value of TOGAF and ArchiMate • TOGAF is designed to be used in many different situations: – Tailor it to your needs – Major focus on getting results – Many guidelines and techniques that will help you be successful • ArchiMate has built-in capabilities for cross-domain modeling, analysis as well as advanced visualizations for various stakeholders • Both open standards: – Work well for incremental adoption – Are supported with tools, including BiZZdesign Architect – Have an extensive track record in practice 27

Editor's Notes
- Stress the integrated part of the service offering: because we excel in the different service offerings AND because we understand our customers so well, we can give them what they need. Always. Also stress the brand story: building your business is our business. This links to tooling, but also consulting and training.
- This slide sets the scene for the next two. When presenting this, stress the fact that there are many different definitions for both the “E” and the “A” part, that we (BiZZdesign) follow open standards and go from there.
- Comes directly from the OG standard where “enterprise” is defined as “a collection of organizations with a common goal”.
- Toronto (or any city in north America) illustrates the ISO/IEC definition nicely:Fundamental organization: gridPrinciple: easy navigation, easy to sell lots of ground (in the old days) because they are rectangularContrast that with a maze like Amsterdam where we all get lost. Is also a city (or: big village) but structure is very different, partly because of different design principles
- This one comes from the handbook and has the advantage of combining “EA as product”, and “EA as something we do to get results”. Put this slide on, talk for a while and see how the audience reacts. It is less “technocratic” than the ANSI/ISO definition
- The ArchiMate Framework is built on three layers: the business layer, the application layer, and the technology layer. This means that concepts of the language sit nicely in each of the layers. More structure is added by distinguishing between concepts that represent “things that show behavior” (active structure), behavior itself, and things that undergo behavior (passive structure). Lets look at some real concepts:In the business layer we see how actors perform roles in processes. Processes realize business services, which are the services we offer to our environment. Typical examples are the fact that customers can buy a bike, or insurance on that bike. The business object is the unit of information in this layer.In the application layer we see a similar structure. In the active sturcture column there are applications and interfaces, which model how to gain access to the behavior of these applications. Application functions whereas services are the behavior that applications offer to their environment: either other applications or to the business layer.The same pattern can also be observed in the infrastructure layer where logical nodes have both internal behavior, modelled by functions, and external behavior, modeled by services.All in all there is a lot of symmetry between the layers, as can be seen by looking at the relations. A full explanation is beyond the scope of this presentation, but at least note that the same relation type is used each time when crossing from active structure to behavior and to passive structure.
