Good enough definition of EA
Enterprise Architecture is
the art of making sure that
the right people do
the right things in
the right place at
the right time!
How?
Why?
Who?
What?
Where?
When?
Question 1:
Which one of these do You
cover in the answers
that your EA work provides?

Different usage of the information, from perspectives of different
stakeholders, is a challenge for the EA repository.
Question 2a: What is the focus area of your EA work?
Question 2b: Who are your stakeholders?
Question 2c: What information do you deliver to them?
Question 2d: What information do n’t you/them have?
Question 2e: Where do you find/create all that information?

Question 3: In which areas do you have the most current/reliable information about
how your company’s EA looks like and performs in reality?

Question 4

Assuming that your EA work:

Is quite successful :




You have good enough information about what you need to know
And You are able to provide good enough information for your
stakeholders,
then what is wrong with the tools that you already use?
Or is not as successful as it should be or perhaps it is in the
beginning phase and you still don’t know if it will succeed:

then what is wrong with the tools that you already use?

HOW TO SELECT AN EA TOOL

Gartner says

It is a view of the
market as a
whole.
 Best EA tool for a
given organization
might well be
outside of the
Leaders quadrant.
 Often, niche
problems reuire
niche solutions.

How to select a tool that is better than what
you already have:








Decide which areas are in focus of the EA work
Check evaluation guides (links available in ”More information”)
Create customized checklist from above
Evaluate the existing tool(s) according to the checklist
Evaluate the selected EA tools according to the checklist
Decide which EA tool to go on with
Plan and define the scope of a Proof-of-Concept
Perform a Proof-of-Concept




Through a minor (or preferably none) customization of the tool’s repository meta model and
And a quick evaluation of integration with your current repository, documentation, communication
and reporting tool(s)
Analyze, define and report the findings and the short-term implementation roadmap
And when the tool is in place:

Implement a real-life pilot (from a real-life stakeholder’s perspective)


Analyze and make the adequate adjustments to the implementation roadmap
Follow the implementation roadmap, stepwise and with the adjustments due to your own (which
should be equal to your stakeholders) prioritizations

LESSONS LEARNED

Lessons learned

If you can manage your EA approach by using the tools that
you already have, then you will be able to get it done even
with an EA tool
Documentation & Repository tools



Analysis & Design tools
One tool does not do it all for all stakeholders
Prioritize and decide what and for whom and
in which tool
”A fool with a tool is still a fool”

Even if an EA tool will improve the process and increase the quality of
your work with EA, they usually slow it down a bit at the beginning. It is
recommended to avoid to start your EA initiative by bringing in an EA
tool at the same time.
An EA tool implementation is not different from other tools
implementations. Start small and deliver results that your stakeholders
can use in their day-to-day work from day 1.
Automated information gathering and distribution is a key success factor
for the EA repository.
My personal opinion is still that most EA tools are:



Really good for As-Is and To-be documentations, when it does not fit into
some Excel sheets
Quite helpful for communication of your EA work
As good as Excel and other Office tools for simple but yet useful analysis
