Identifies & classifies what are the EA artefacts/components & their taxonomy structure

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?

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 one of the following changes:

1. A corporate level strategy, or2. A business level strategy, or3. A product level strategy,

check if EA changes are also needed

Time span may be annually or as when needed within a year.

What is a methodology?

General Definitions

Methodologies are discipline specific approaches and processes(Kinash, 2014)

In research, a methodology describes HOW research is systematically conducted, including disclosure of methods, why the methods were chosen and the limitations of the methods (Oregan State University, 2012)

Research methodology is an approach that systematically solve a research problem (Ansari, 2012)

What is an EA Methodology?EA3 Methodology Definition

“The EA Methodology defines how the EA will be implemented and how documentation will be developed, archived and used, including the

selection of a framework, modelling tools and online repository”

= HOW TO guide= Process guide

Revitalising an existing EA program

Revitalise an existing EA program = improving an existing EA program

MCQ6 : When revitalising an existing EA program:

a. EA methodology should involve strict/rigid additional steps b. EA methodology should focus on the selections of different frameworks . c. EA methodology should focus on identification of a new Chief Architect d. All of above

What do you think is the answer & why?

Part B: Discussion Questions

Q1. What is an EA implementation methodology?

Q2. What is the role of an EA framework within the EA methodology?

Q3. What is the purpose of Phase I activities in the EA methodology?

Q4. Why are Phase III activities dependent on the completion of Phase II?

Q5. Compare and contrast the purpose of Phase II and Phase IV activities.

Q6.Can the steps of the EA methodology be changed for different enterprises?

Q7.Who is responsible for execution of the EA program and EA methodology?

Q8.How often should an EA be updated? Why?

Q9.Select a real world medium or large size enterprise and provide:a) The phases and steps of an appropriate EA implementation methodology.b) The way that EA stakeholder support will be obtained.c) The recommended schedule for updating the EA.
