ACCLAIM FOR BUILDING AN ENTERPRISE
ARCHITECTURE PRACTICE
“Enterprise Architecture has been an ‘emerging’ discipline for quite some time now,
with a plethora of literature repeatedly providing mostly theoretical speculations.
This book fills the urgent need of providing a pragmatic approach to converting
those theories into a meaningful, viable, and useful architecture practice within an
enterprise.Inadditiontoaddressingthekeyaspectsofanarchitecturepractice,thebook
alsooffersseveralvaluabletools,suchastheDYAModelandtheArchitectureMaturity
Matrix, helping tailor and develop the most suitable architecture strategy for a given
enterprise.”

“DYA is THE practical framework for architects. It focuses on the process and
deliverables of the architectural services. DYA gives suggestions how EA can be
structured,butit’suptotheorganisationtochooseanyEAframeworkasbaseforDYA.
This book gives, by way of examples and best practices, guidelines how to implement
thearchitecturalprocessesandoutlinestheservicesanarchitectshoulddeliver.
The philosophyDYA drums into the reader, ‘just enough, just in time,’ appeals to us.
When addressing EA, don’t grasp it in one bite. Do it the DYA way, bit by bit in a
structuredandcontrolledmanner,justenoughjustintime.Inotherwords,growwith
