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?

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

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.
