1/25/17 5 Enterprise Architecture What is Enterprise Architecture? Simple definition: Enterprise Architecture is a strategy to minimize IT and business mistakes
1/25/17 6 Enterprise Architecture Program Cost focus Value focus. EA is a journey, often non-linear Tactical, opportunistic Strategic, systematic Cost Reduction What do we have? Need all of it? Consolidate to reduce costs? Desire for impact analysis Standardization Develop standards and recommended best practices (e. g. technology stacks, server platforms) Seeking repeatability Encourage IT evolution Focusing on IT scope only Broaden Scope Meet business needs by linking IT to business Managing architectures outside IT Increasing focus on business architecture and business processes Realizing Strategy Develop business strategy Value propositions, capabilities, resources Refine into to-be Compare to as-is Create transition plan Execute Enterprise Architecture has to be treated as an ongoing program that continues to evolve together with the organization
1/25/17 7 Enterprise Architecture Determining Your Path Self awareness Standardized technology Optimized core Pervasive governance EA Maturity. Low High. S trategic Tactical IT / B usiness Im pact. Laying out a vision of the Enterprise Architecture Program’s maturity is one of the most important first steps in ensuring its success and longevity * Based on MIT Sloan Center for Information Systems Research EA maturity model • Self awareness – Recognizing the problem – IT leadership starts the EA program • Standardized technology – Establishing technology standards – Moving to a shared infrastructure model • Optimized core – Moving from local to enterprise view of technology assets – Standardizing core business processes – Establishing core technology assets • Pervasive governance – Establishing effective centralized EA governance – Federation of
1/25/17 8 Enterprise Architecture Maturity Model • Stakeholder Support and Involvement – The involvement and support of the primary stakeholders – Includes all EA stakeholders • Team Resources – Skills and talent level of Enterprise Architects – Tools and support available • Architecture Development Method – Process to define architecture goals and outcomes – See EA Lifecycle • Organizational Integration – Integration with other processes and organizations • Deliverables – Existence of actionable EA deliverables – Alignment with EA lifecycle • EA Governance – Formally established EA Governance – Broad visibility across the organization • Metrics – Set of clearly defined metrics – Broadly understood and communicated • Stakeholder Perceptions – Perceived value of the EA program by the stakeholders – Indication of success or failure. Many EA Maturity Models exist. Choose the one that works best for you and adopt it. It will provide a prescriptive guidance and define the levers you can pull to maximize EA maturity. EA Maturity Dimensions
1/25/17 9 Enterprise Architecture Starting the EA Journey Gartner recommends establishing and evolving the EA program via six major phases.
1/25/17 10 Enterprise Architecture Lifecycle Create the Enterprise Architecture vision and program structure Document current state architecture Develop future state architecture Create a roadmap of transitioning from current state to future state. Establish and execute governance processes. Develop business case(s) for the initiative(s) identified on the roadmap EA lifecycle is a series of continuous iterations over these phases * Based on Oracle Enterprise Architecture Framework
1/25/17 11 Enterprise Architecture EA Governance * Based on TOGAF Alignment • Enterprise Architecture establishes a number of governance mechanisms – Architecture Board serves as a governance body ensuring IT initiatives align with EA – CTO and/or Chief Architect provide stewardship and guidance – Enterprise Architects develop policies, practices, and processes that the Architecture Board supports • Enterprise Architecture and IT leadership ensures alignment with business goals, strategies, and objectives
1/25/17 12 Enterprise Architecture Recipe for EA Program Success The need should be evident (IT inefficiencies, duplication of capabilities, etc. ) Ideally, this should be a C-level exec. Start with highest possible level and aim for C-level sponsorship. Organize and announce the team. Clearly establish scope, charter, and responsibilities. Concentrate on low hanging fruit such as cost savings, platform and capability consolidation, etc. Make all IT leaders responsible for EA success with specific goals and objectives. Formalize all EA governance bodies and processes. Integrate them into all aspects of IT operations. Ensure universal adoption through executive (CIO / CTO) mandates and objectives. Incentivize positive behavior. Make everyone aware why EA is important to them and what value it brings. Concentrate on aligning business and IT strategy once core EA program has matured sufficiently.
1/25/17 13 Enterprise Architecture Keys to Success It is very hard to sell EA on its value alone. While there are many ways to demonstrate value, it is often not realistic enough for executives to grasp. Instead, identify real needs to establish the EA program and focus on showing results quickly. Once everyone sees the value, it will be easy to justify continuing investment. Frequently publish metrics to demonstrate progress.
1/25/17 14 Enterprise Architecture Designing an Effective EA Program From centralization to federation • Centralize at first to accelerate maturity – Establish a central EA team – Define and enhance all the EA processes – Pragmatically and systematically drive EA adoption • Exercise EA governance cautiously – Establish an Architecture Review Board – Slowly increase its scope and influence • Plan for federation – Ensure all the processes and structures can be easily federated when needed • Federate when enterprise is ready – Pull the trigger when the enterprise is mature enough for federation – This typically happens when EA is universally accepted and is not questioned • Align Enterprise Architects with business units – Absorb Portfolio Architecture functions – Ensure clear alignment between EA and Portfolio Architecture • Maintain governance and planning functions centrally – Keep Architecture Review Board as a central governance body

1/25/17 16 Enterprise Architecture Achieving Success EA is universally accepted Everyone (from executives to developers) believe in EA vision, mission, and purpose EA Governance is invisible yet omnipresent EA processes are tightly woven into the IT fabric A system to incentivize positive behavior and penalize negative behavior is in place Everyone understand their role and value they bring to EAThe success of an Enterprise Architecture program is hard to measure in objective terms. It is not just how much savings was achieved, what percentage of enterprise was modeled, how many roadmaps were created, etc. The primary indicator of success is the degree of change in the company’s culture. Below are the signs of what a successful Enterprise Architecture program looks and feels like.
