Enterprise Architecture Overview November 2006
Our Areas of Interest • Business – HE Functional Reference Models • Platform Standards – Taxonomy • Architecture Governance • What other Universities are doing in this space • Methods/Tools being used to achieve goals of EA November 2006 3
Where we have come from • Organisational change – 2005 restructure • Legacy Technology unable to support the business going forward • Little or No standards / methodology • No one overseeing the “bigger picture” across the organisation • Decentralised IT November 2006 4
Enterprise Architecture and Uo. N • Very early stages • Major business and systems change § Organisation Restructure completed early 2006 § Centralised IT § Program of Works (EPMO) within IT § Formation of roles/groups (AAG, CAB, Po. W, Change Office, IT Governance Committee) • Introduction of Groups and Processes § Start of ITIL implementation, Change Office (PMO), “formalised” Project Methodology and SDLC, Architecture Governance, Standards • Enterprise Architecture Consultant – “EA in a box” § Light inventory across Business, Information, Applications, Technology § Provided principals, some mapping between inventories, gap analysis § Current Activities/Changes/Lack of Ownership made this difficult – “hitting a moving target” § Tool - System Architect November 2006 5
Enterprise Architecture and Uo. N • 2006 Program of Works § 50+ Projects with IT underpinning them § Infrastructure (network, server consolidation, etc) § Information Management (BI, ECMS) § Business (HR, Finance, Research, Students, Facilities, etc) § Teaching / Learning (Blackboard/LOMS, Academic Support) § Operational (ID Mngt, Integration, adopt mainstream technology) § Client Services (“ 17000” Centralised Service Desk, MOE, ITIL rollout) § NUWays: Focussed on Business Process Improvement and EPMO • Formed § Change Office § AAG – Architecture Advisory Group § CAB – Change Advisory Board § Project Portfolio’s – Program of Works November 2006 6
Enterprise Architecture and Uo. N • Currently only used by IT § Covers Po. W and operations § Reaction to the amount of project work being undertaken, realisation for EA out of Po. W • AAG Membership § Enterprise Applications § Solutions Architect § Infrastructure § Security § Data Services § Client Services § Web Group § (Note: No Business Representation) • Bottom up approach to EA – driven by IT November 2006 7
Challenges Experienced • Current IT Inventory = 100+ Main Applications § ~65% in-house developed – mainly “gap fillers” around the enterprise applications § Current upgrades will supersede some but still expected to be significant § Mixed blend of technology: Ø ERP, disparate systems Ø old and new technology Ø “islands of data” and “the spider web” of integration (point to point) • Time / Resources / Size of Work for Enterprise Architecture • Standards / Guidelines • Expectations of Business and IT • Implementation, Acceptance and Understanding of Enterprise Architecture within IT • Seen as a hold up for existing processes / projects November 2006 8
Our Enterprise Architecture Framework Business Model • Business Direction • Stakeholders • Functions • Information Business Architecture • Data Model • Information Flows • Databases • Applications Information Architecture Application Architecture • Application Integration • Application Technology • Server Technology • Network / Communications • Platforms / Operating Systems Technology Architecture • Database Systems • Security Technologies • etc. November 2006 9
Architecture Development Process Business and IT Strategies ensure that architectures align with business needs and priorities Business Strategy IT Strategy Policies Principles give high level direction to enable decision making Enterprise Architecture Principles Technical Application Information Business ig h High-level context diagrams present broader picture Detailed models describe the subject matter at a project level et ai le d M ed iu Subject area models provide the linkage between the global context and projects D Target Model T 2 T 1 November 2006 Current Model Transition Plans provide the implementation “roadmap” m H Architecture layers provide linkage between business models and technical architecture Technology Standards and Guidelines Standards and guidelines provide specific direction on implementing 10 architectures

Where to from Now? • Adoption of Use of Enterprise Architecture outside of IT • Establish an EA group with a business focus • Learn and improve • Work collaboratively • Continual Development of Enterprise Architecture with alignment to the strategic direction of Uo. N • Become proactive rather than reactive November 2006 18
