| How do you
get continuing value from IT Architectures? |
|
| IT
Architectures are enjoying a renaissance.
CIOs are updating yesterday’s architectures,
or working on creating new ones. The reason?
IT Architectures promise benefits that are
more sought after than ever. But they are
not always easy to explain to non-IT Colleagues. |

| The City
Planning metaphor |
|
Why is this
metaphor interesting in the field of information
system? Is it only a marketing hit?
The reason of the spread of this metaphor
is the similarity between information system
and city problematic. How to remake, modernize,
how to benefit from the breakthrough without
erasing the past , within limits of controlled
costs, while maintaining the life in the city
during work?
In the fact, Information System takes from
“City Planning” its vocabulary,
best practices and key deliverables. The use
of City Planning vocabulary is an easily understood
metaphor that architects can employ to communicate
more effectively the nature and value of architecture
by relating the “unseen” enterprise
architecture to real-world concepts that are
well understood.
One of the key deliverables is the local plan.
Local Plans set out detailed policies related
to the use of the land. In the Information
System case, the scope of this document is
the company and set out the rules applying
in the use of information system parts. |
