Need Enterprise
Architecture?
In many sectors:
•The business strategy changes quickly
•Technology is rapidly evolving.

must swiftly adapt to these changes.

21. Why Do We Need
Enterprise Architecture?
IT infrastructure (hardware and software) and the businesses
organisation and processes change relatively slowly.

22. Why Do We Need
Enterprise Architecture?
Enterprise Architecture bridges the gap between the rapidly
evolving environment and the slowly changing IT infrastructure
and business processes.
IT infrastructure (hardware and software) and the businesses
organisation and processes change relatively slowly.

23. Without Enterprise
Architecture, each
change, to
accommodate a new
business strategy, is
implemented in
isolation.
What Happens Without Enterprise Architecture?

24. Without Enterprise
Architecture, each
change, to
accommodate a new
business strategy, is
implemented in
isolation.
What Happens Without Enterprise Architecture?
This creates a web of
individual applications
and processes which
often interact with
each other and the
databases and will
likely not have been
well documented,
leading to an overly
complicated system.
