An Introduction …….
This is an abridged version of the EA Forum presentation2Copyright © Real IRM Solutions (Pty) Ltd 2016“Interest in business architecture is growing dramatically. During the past
two years both IT and business leaders have joined the discussion about the
need for a well -defined business architecture.
Though there is a great deal of discussion, there is little consensus about
what business architecture is, how it should be pursued, and what value it
delivers.
Business architects in IT as well as in the business have started developing
business -unit-wide and enterprise- wide business architectures, learning
as they go. Their ultimate goals are to improve business decision- making
and facilitate better alignment between IT and the business units it supports.
Architecture teams that want to play a leading role in business architecture
development must start soon or be left
behind.”
