  2. TOGAF EA Methodology Source: http://bmsace.blogspot.com.au/2011/04/togaf-notes-part-3.html

  3. EXAMPLE: Use of TOGAF Methodology for Risk & Security Segment (source: http://www.infoq.com/news/2011/11/togaf-sabsa-integration?sf2540612=1

  4. Example of TOGAF Modelling Components

  5. Cataloguing the EA artefacts

  6. Zachman Framework BUTNo methodology defined Identifies & classifies what are the EA artefacts/components & their taxonomy structure

  7. So what is in EA Work? Methodology How to do Based on EA Framework How to organise Steps involved are PROCESS Involved Outputs Inputs

  8. Think Through Aspects of EA Program Management • 1) Which parts of the organisation are you implementing EA? • If all good • If part – understand the EA limitations 4) What methods/techniques to use to document and model requirements and design artefacts? 3) What how to organise & format documentation? 2) EA Governance – checking EA compliance & risks mgt – is it centralised or decentralised? 5) What software tools to use for modelling & documentation? 7) When to update? 6) Where to store & how to access?

  9. Given the mandate to develop 2 segments of DMC’s EA. First deliverable: business case & EA Dev project plan Produced Meeting Discussion Highlights 2 Critical Success Factors Inclusive stakeholder involvement Agreed EA Methodology DMC EA Plan: Financial & Production Segments Report EATeam Elaborate the EA Approach / Methodology proposed in report • EA Development timeline • EA modelling steps involved • Planning & decision making information specs, including preferred documents’ formats • Selection of EA modelling techniques & tools • EA scenarios – Current & Several Future views • Agreement of planning assumptions • Evaluation of Kate/Jim’s systems and retrofit in EA scenarios • Explanation of how the EA methodology’s framework to structure DMC EA and guide its various EA modelling/ documentation activities Scene 3 Meeting Outcomes: Agreed EA Methodology & EA Documentation Framework Next Meeting Goals: Understand how the 2 outcomes are used to document the current & future models of Jim + Kate’s business units/departments

  10. Given the mandate to develop 2 segments of DMC’s EA. First deliverable: business case & EA dev project plan Produced • Inferred Business Case Contents • Chosen Jim/Kate’s areas as the 2 EA segments because they cover several lines of business (LoB) • Analyse DMC’s strategic goals, business activities & technology capabilities • Specified the 2 areas’ business and ICT requirements DMC EA Plan: Financial & Production Segments Report EATeam • Inferred Methodology Contents • EA Development timeline • EA modelling steps involved • Planning & decision making information specs, including preferred documents’ formats • Selection of EA modelling techniques & tools • EA scenarios – Current & Several Future views • Agreement of planning assumptions • Evaluation of Kate/Jim’s systems and retrofit in EA scenarios • Explanation of how the EA methodology’s framework to structure DMC EA and guide its various EA modelling/ documentation activities This Meeting’s Goals Achieved: To Agree the proposed EA Methodology & EA Documentation Framework Scene 3

  11. Case Study Qs What are DMC’s EA methodology phases & steps? How does DMC obtain stakeholders’ support? Recommend DMC a schedule for updating the EA

  12. Clues to the phases & steps involved in EA work Step 1: Identify all stakeholders & form project team Step 2: First meeting with project team to ensure understanding of the EA Methodology • What’s involved in the methodology? • Develop the business case, which also contain the business & ICT requirements for the 2 proposed systems • Modelling phase • Inputs: • Business planning & decision making information • Documentation formats • Modelling techniques & tools • Processes & outputs • Current environment modelling • Future environment scenarios modelling • Future scenario recommendation Step 3: Stakeholders agree the EA Methodology & expected modelling outcomes

  13.

  14. Examples of EA Development Timelines Phase by Phase Q1 Q2 Q3 Y2 Q2 Q3 Y3 Q2 Q3 Agile – Iterative Concurrent Phases progressing

  15. How often to change EA models/documentation? Every time : A corporate level strategy A business level strategy A product level strategy The ICT infrastructure is replaced Check if EA changes are also needed Time span may be annually or as when needed within a year.
