3. When we talk about Enterprise
Architecture…

4. People are
usually
puzzled

5. Or, have
moderate
enthusiasm

6. …because additional efforts will be requested

7. And habit
changes are
rarely welcome

8. Enterprise Architecture definition gives some
clues
Enterprise architecture (EA) is the process of
translating business vision and strategy into effective
enterprise change by creating, communicating, and
improving the key principles and models that describe
the enterprise’s future state and enable its evolution
-- GARTNER

9. But what really is Enterprise
Architecture?

10. Information Technology (IT) is no
longer considered as a set of
tools…

11. If the Enterprise is compared to a
house…

12. IT is rather the house frame
and…
Foundatio
n,
Electrical
network,
Waternetwork,…

13. So the Business team can fully enjoy their
business life

14. When you are performing big changes in your
house,

15. It is better to
have a plan of

16. Enterprise Architecture is the plan of
your Enterprise and the IS/IT
supporting it

17. Enterprise identity can be summed up
with :
Its Strategic
Goals
Its Business
Processes
Its Organization
Structure
People Skills and Know
How

18. IS/IT can be modeled
by :
Dat
a
Business Processes and
Roles
Applications and IS
functions
Infrastructure

19. Enterprise Architecture is a repository where all
attributes of Enterprise and IS/IT are stored

20. “This is
consuming a
lot of
resources to
set up and to
run, only for a
plan!”

21. What is the Value of
Enterprise
Architecture?

22. Secure alignment
between Enterprise
Strategies and IS/IT
First value of Enterprise
Architecture

23. Imagine two teams playing the bush
telegraph

24. And one
team is
using an aide
to explain the
message to
spread

25. It is easy to guess who
will win the game

26. In the business world, we unfortunately always play bush
telegraph,
especially when we are dealing with IS/IT projects

27. It is a difficult game because most of the
players are speaking different languages
IT
language
Business
language

28. Biz

And the number of players involved in the game
is big

29. So
sometimes
deliveries
produce
unexpected
outcomes!

30. Enterprise Architecture is the
support aide of the bush
telegraph game for an
Enterprise

31. Enterprise Architecture aligns IS/IT
developments with Business expectations by…

32. using a single language understood
by all parties : The Business
Processes

33. Support Long term
valuable
transformation
Secondvalue of Enterprise
Architecture

34. Business Teams are
usually very
ambitious with their
requirements

35. Thus,
transformations
Cost a lot of
money
Take
time
Are
complex
And
risky

36. It is safer to reach the targeted goal step by
step

37. There are two different
options to be sure that
steps are following the
right direction

38. First option is to invoke divine
power

39. Second option
is to use a
map

40. It is easy to guess what is
the better option

41. Enterprise
Architecture
provides the map to
guarantee that steps
are going in the
right direction

42. Thanks to Enterprise Architecture, each IS/IT
evolution (project) is a step towards a shared
target (program) and is no longer a single initiative

43. A long term view is critical to allow IS/IT
capability to adapt to further evolutions

44. And this is a question of life or
death for IS/IT and the

45. Identify where
optimization
can occur
Third value of Enterprise
Architecture

46. Today, competition
between companies
is fierce

47. Every savings
or
optimization
will procure
precious
trumps

48. Companies that have indicators on the
value of their activities have a head
start

49. Enterprise architecture is providing these
indicators
ROI of each
activity and
Process
Cost of
duplicated
Processes and
tools
Complexit
y

50. So managers will be able to take decisions thanks to
figures vs based on beliefs

51. Support Business
Continuity
Fourth value of Enterprise
Architecture

52. In today’s information age, IS/IT is definitively one
of the key assets of the Enterprise
Dat
a
Business Processes and
roles
Applications and IS
functions
Servers and
Datacenters

53. It is not safe to not
protect the key
assets

54. But it is too easy to leave this asset in the
head of some experts

55. When experts leave the company, is it
acceptable for the company to loose this
asset?

56. Enterprise architecture describes the knowledge in
some experts’heads and shares it with the rest of
the Enterprise

57. CONCLUSIO
N

58. Indeed Enterprise Architecture is requesting…
Methodolog
y
Additional
efforts
Changing
habits

59. …but is company able to compete without
the trumps provided by Enterprise
Architecture?
