“I enjoyed reading this book. It was as if Grigoriu had laid out all the
business and IT elements that make up an enterprise on a table and then
played around until he could fit them all together into a single cube – an
ingenious effort at puzzle solving…

I would happily recommend this book to anyone who is already an
experienced enterprise architect. This book is an excellent “graduate
review” that will force you to think through lots of issues and consider how
you might address them in your own architecture.

I would also recommend this book to someone who was interested in the
issues involved in building a business case for an Enterprise Architecture
effort – the sections on benefits and costs are excellent and comprehensive
–

and I’d also recommend this book to someone who wanted to learn
more about how to classify stakeholders. The section on strategy and
stakeholders is outstanding”.

Paul Harmon, the Executive Editor of Business Process
Trends (www.bptrends.com), a recognized BPM analyst and consultant and
the author of Business Process Change.
The Problem: today's unresponding “legacy” Enterprise in a world of
increasingly increasing complexity, amount of information, rate of change and
competition.

The Solution: the Enterprise Architecture (EA) offering streamlining,
alignment, blueprinting, strategic planning, and agility through SOA, the target
state of the Enterprise.

The book describes:

drivers, benefits and Business Case for an EA evaluating financial
Payback and NPV

Enterprise reference maps, covering business and technology architecture
templates

alignment of your on-going solutions architecture projects to the
Enterprise Architecture

a navigable EA framework and its metamodel describing the Value
Chains, Business & Operating Models, Functions and Flows resourced
by Organization and Technology layers

classification of and mapping to other EA frameworks: Zachman,
TOGAF, DoDAF…

a unifying view of EA, Service Oriented Architecture (SOA), Value
Chains, Business Models, Processes (BPM) and IT Architecture,
patching the divide between the Business and IT

a best practices process for building the EA and SOA,, an EA
development exercise, and how to use the framework for ITIL, M&A,
Outsourcing, Start-ups…

EA patterns, inhibitors, maturity models, politics & sell

a Strategy specification process and alignment to business activities,
organization and technology.

“There are a few books that take a broad perspective, but most focus on
creating an IT architecture. An Enterprise Architecture Development
Framework, by Adrian Grigoriu, is a pleasant exception. Grigoriu takes a very
comprehensive view of things and works to show how everything can be
integrated within a broadly conceived view of things”.
