To understand Enterprise Architecture and make it understood

1. THE ULTIMATE
TOOL TO
MANAGE
INFORMATION
TECHNOLOGY.

2. “ Power is nothing without control” (Pirelli)

3. When we are talking 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’s 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 GROUP)

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…
Foundation, Electrical network, Water network, …

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

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

15. It is better to have a
plan of your house.

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 :
Data
Business Processes and roles
Applications and IS functions
Servers and datacenters

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
IS/IT and Enterprise
Strategies
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 Analyst Architect Offer Mgr Customer
And the number of players involved in the game is big.
Developer

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
Second value of Enterprise Architecture

34. Business Teams are
usually very ambitious
with their requirements.

35. Thus, transformations
Cost a lot of moneyTake 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 Enterprise.

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
Complexity

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.
Data
Business Processes and roles
Applications and IS functions
Servers and datacenters

53. It is not safe to not
protect 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. CONCLUSION

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

59. But what company is able to compete without the
trumps provided by Enterprise Architecture?

60. Thank you !!!
