7. According to CIO surveys, improving business processes continue to be major areas for investment. SOA and BPM are key enablers for these. In today's economy, how do you justify ongoing SOA investments and ensure SOA success? Centers of Excellence (CoE) for SOA and BPM are cost-effective ways of disseminating methods, techniques, best practices, and educating the wider IT community. CoEs also form a key part of SOA Governance approach. In this session we will outline best practices and Nordea's experience in justifying and running a CoE, and the benefits that have been derived across Nordea. A key focus area for the session will the role of a CoE in driving SOA education. According to CIO surveys, improving business processes continue to be major areas for investment.

8. Why SOA, Why BPM For many reasons. Different reasons; depending on the what your Business needs to achieve or avoid: Gain efficiency and excel in business operations Evolution rather then revolution The world is dynamic and ever changing. We need the ability to adapt. Fast and with a minimum of cost – without creating obstacle for the future changes. The competition requires that we excel in our operations. We cannot outshine and outrival in everything. We must co-operate with others and prepare for these kind of cross business co-operations.

11. Incentives for SOA Achieving Cross Channel Integration The same process across channels Reuse the same services X-Channel Reuse of Data and host transactions Cross Channel Integration Enabling Business Flexibility Enhance process(es) swiftly Separation of concern, eg., IT vs. Business Reuse of Services and Cost Savings Enabling Business Flexibility And Change Reuse of Services Cost Savings Shorten Time to Marked
12. When asked what single eventwas most helpful in developing the theory of relativity . . . Albert Einstein is reported to have answered: So what is the problem we want to solve? . . . not the solution “Figuring out how to think about the problem.”
13. What is a (financial) product? Bank Customer says … Loan, Account, Card, E-bank, etc. Branch office employee My service … the way I interact with the customer IT Developer The Loan System, the Account System, etc Enterprise Architect A mathematical model £ € $ f(x, y, z) = (a, b, c)

23. High Level Introduction to SOA Why are we going for SOA in Nordea Business and Technology Context for SOA in Nordea Reference Architecture What are we going to do Architectural details … layer by layer Cookbooks and Guidelines How-to do in each layer Design guidelines Web-Based (Wiki) How-To instructions Reference Applications Two Reference Applications to demonstrate how instructions are materialised. SOA Overview Reference Architecture Reference Applications Design Guidelines and Cookbooks The Blueprint of SOA in Nordea Gover- nance Opreational Processes Tools and Templates
24. Govern the lifecycle of a service Contribute to and support Change projects Spread know-how on SOA SOA Centre of Excellence SOA Academy: This unit would spread the knowledge of SOA in Nordea. It identifies the Roles and the Skills, which Nordea needs to run SOA. The Academy would arrange courses and partner with the vendor on this topic. SOA Academy SOA Support Centre SOA Design, Governance & Policy Body SOA Support Centre (SC): This unit supports the Projects in their initial and critical phases. The members bring back valuable learning points to the CoE and help updating the architecture. They play an active role in SOA Academy. SOA Governance: This unit would quality assure and approve/disapprove the SOA design in various front-end programmes. Furthermore, it owns and is responsible for maintaining the SOA documents and guidelines, due to best practice, learning points form projects and emerging technologies. SOA Centre of Excellence
25. SOA Support Center. Support as a part of Governance
26. CoE will Allocate one Lead Architect to each Project. Up to 80% allocations Option of allocating several resources depending on the context Providing documentation on architecture and guidelines Providing tools and features Developing the Enterprise Architecture for the projects Add hoc problem solving Support in Executing the Projects Project Performance Project Life Time
27. Architecture Governance There are Two major approaches for architects to involve in governance processes: The Collaborative model that applies proactive guidance via architect consulting and The Review model that creates an architecture review board at the (NIIDS) project gates in the development and implementation process. EA groups should ensure that they are involved with governance at multiple levels (as described in previous slides) The Collaborative approach is much more value adding process to the business. (See the SWOTs on the following slides.) Hope is good … but it is no Strategy The key to EA efficiency is governance. The key to governance is the right level of intervention in IT projects.
28. Collaborative Governance Approach Collaborative Governance Approach Strengths Weaknesses Collaboration eliminates the “us and them” symptom. Involvement in early phases of a change reduces risks, redo-s and leads to more intelligent designs EA gains influence and leads Nordea towards the business targets proactively Reduces the need of review and bottlenecks atthe project gates. Streamlining use of technology. Challenges in sponsorship of the architects May require a LOB for the architects Enterprise Architects learn more about thebusiness (due to early involvement in thechange planning process). Achieve technical consistency Limit architectural and technical risk. Projects may attempt (mis)use the architects as ordinary project resources. Opportunities Risks
29. Review Governance Approach Review Governance Approach Strengths Weaknesses Projects get reviewed their design prior to the construction phase. No immediate need for sponsorship as a organisational line. EA cannot act proactively Potential design problems are identified after the finalisation of the design process. Redo of design affects the time plan of the projects. Could lead to “Us and Them” atmosphere. EA would not get the opportunity to evangelisethe strategies during the design phase. Easy to invoice the projects. Streamlining use of technology. Involvement in early phases of a change reduces risks, redo-s and leads to more intelligent designs Could lead to “Us and Them” crisis. Opportunities Risks

36. How to put SOA on the Agenda of the Business?
37. Hook your best architects into large intiatives and transformations SOA as a change enabler. Transformation Initiatives Projects Projects Initiatives Projects Projects Projects Small Scale Large Scale Characteristics: Discrete Localized Stable Tactical Short Term Characteristics: Breakthrough Enterprise Destabilizing Strategic Medium Term Characteristics: Continuous Ubiquitous Routine Visionary Longer Term They will be making decisions with little understanding of long- term dependencies or implications. Decisions are based on mid-term horizons and implications. Tend to reuse existing assets & introduce a few new. Long-term decisions, competitive advantages, innovative, build bridges and pave the way for the rest of Nordea.
