EXAMPLE: Use of TOGAF Methodology for Risk &
Security Segment

Example of TOGAF Modelling Components
Cataloguing the EA artefacts
Zachman Framework
BUTNo methodology defined
Identifies & classifies what are the EA artefacts/components & their taxonomy structure
So what is in EA Work?
Inputs OutputsPROCESSINVOLVED
MethodologyHow to do
EA FrameworkHow to organise
Based on
Steps involved are
Think Through Aspects of EA Program Management1) Which parts of the organisation are you implementing EA?• If all good• If part – understand the EA
limitations
2) EA Governance – checking EA compliance & risks mgt – is it centralised or decentralised?
3) What how to organise & format documentation?
4) What methods/techniques to use to document and model requirements and design artefacts?
5) What software tools to use for modelling & documentation?
6) Where to store & how to access?
7) When to update?
EATeam
Given the mandate to develop 2 segments of DMC’s EA.First deliverable: business case & EA Dev project plan
2 Critical Success Factors1. Inclusive stakeholder involvement2. Agreed EA Methodology
DMC EA Plan: Financial & Production Segments
Report
Produced
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
Meeting Discussion Highlights
Meeting Outcomes: Agreed EA Methodology & EA Documentation FrameworkNext Meeting Goals: Understand how the 2 outcomes are used to document the current & future
models of Jim + Kate’s business units/departments

Inferred Methodology Contents• EA Development timeline• EA modelling steps involved• Planning & decision making information specs, including preferred

EA and guide its various EA modelling/ documentation activities
This Meeting’s Goals Achieved: To Agree the proposed EA Methodology & EA Documentation Framework
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
SCENE 3
Case Study Qs
1. What are DMC’s EA methodology phases & steps?
2. How does DMC obtain stakeholders’ support?
3. Recommend DMC a schedule for updating the EA
What’s involved in the methodology?1. Develop the business case, which also contain the
business & ICT requirements for the 2 proposed systems2. Modelling phase
• Inputs:o Business planning & decision making
informationo Documentation formats
• Modelling techniques & tools • Processes & outputs
o Current environment modellingo Future environment scenarios modellingo Future scenario recommendation
Clues to the phases & steps involved in EA work
Step 1: Identify all stakeholders & form project teamStep 2: First meeting with project team to ensure
understanding of the EA Methodology
Step 3: Stakeholders agree the EA Methodology & expected modelling outcomes

How often to change EA models/documentation?
Every time :
1. A corporate level strategy2. A business level strategy3. A product level strategy4. The ICT infrastructure is replaced
Check if EA changes are also needed
Time span may be annually or as when needed within a year.
