Major changes in technology have not been driven by the technologies
themselves but by the change in thinking that they enabled. OO design
changed software by changing thoughts away from procedures and onto real
world "things". This book argues that for SOA to succeed we must move
our thoughts away from the implementation technologies and towards the
"what" of the business. Using a straight-forward, pictorially driven,
methodology the book explains who to discover what the business services
really are and how to construct an overall business service
architecture. The book covers defining the Business Service
Architecture, how to classify services for business value and delivery,
understanding the role of IT in supporting the architecture, how project
and portfolio management needs to change, how to use a Service
Architecture to identify KPIs, and how and when to use Business Process
in a service architecture.
