Enterprise Architecture is having a revival and this is mainly being
inspired by SOA.
EA has gained momentum in the last 10 years for
a variety of reasons. Perhaps the most important is the acceleration
of market changes for organisations, and as a consequence
the concept of business agility has become a strategic imperative
for long term survival and growth. However, quick and effective
changes are not possible today without changes to IT systems and
infrastructures - EA's challenge is to make IT cheaper,
more strategic and more responsive.
It's approach is basically city planning for IT; an overarching
plan of the total data, business processes and IT assets inside
a company, how they're used, and how they should be built and shared.
However - standardising, mapping and controlling IT assets do not
make the business obviously more flexible, capable or profitable.
As a result, past EA architecture efforts often stall, fail, or
become just IT-centric.
The emergence of SOA, however, provides new
ways for designing more agile, more responsive enterprise architectures
that provide the kind of value the business has been seeking. With
these new architectures, IT can build new business capabilities
faster, cheaper and in a vocabulary the business can understand.
SOA does not define EA, but it can form its new core. Organisations
who build EA's without SOA will miss an opportunity to address the
two most enduring complaints that the business has leveled at IT:
slowness and inflexibility.
Griffiths Waite is a contributing member of the main TOGAF workgroup
and the SOA project team. TOGAF - The Open Group Architectural
Framework is the emerging standard for Enterprise Architecture.
Having established a key foundation in Business and IT architectures
TOGAF has now established a SOA working group that is starting to define the architectural frameworks
and standards around SOA and the related Ontology's.
Griffiths Waite are synergistic with the leading
edge thinking and developments in Enterprise Architecture and SOA
development and provide effective leadership
and advice to our clients on the Enterprise Architecture Strategies
and SOA roadmaps.
