To enable business agility, service oriented architecture (SOA) needs to be
extended beyond technology to embrace business strategies, processes, capabilities,
sourcing, organization, and people. This broader approach to services can be
called "Services Thinking."
Services Thinking defines and builds business capabilities, the core set of
abilities to answer the question "how do we create value for our customers
and return to our shareholders?" We believe these capabilities transcend
business processes, organizational structures, and technology solutions, allowing
the essence of the problem to be understood independent of the underlying tactical
solutions.
As the creation of these capabilities are prioritized and deconstructed into
strategic objectives and initiatives, underlying business processes and services
can be more effectively identified and delivered. This should allow an organization's
strengths and competitive advantages to be more effectively leveraged to help
them overcome inherent complexities and inflexibilities.
Services Thinking is a departure from traditional definitions of SOA. But that
is why it has resonated with so many organizations. By early 2009 most companies
have some experience with SOA, from freestanding pilots to comprehensive company-wide
mandates. But not many have found the dramatic successes envisioned.
We believe the reason for the lack of apparent success with SOA is twofold.
First, there's the limited traditional definition of SOA. The scope of SOA initiatives
is too often restricted to the technology arena, focused on interfaces and the
movement of data between systems and the implementation of vendor tool offerings.
Ignoring organization, business process, and the rest of the technology domains
(application development, infrastructure, security, etc.) greatly limits the
potential benefits of SOA.
Here, the Services Thinking approach helps address this shortsightedness, helping
companies in their efforts to drive big picture perspective across all affected
functions. By starting with the entire potential solution and refining into
specific tactical initiatives, the Services Thinking approach better positions
companies to achieve a comprehensive scope, but one that is pragmatic in planning
and execution. The result should be a roadmap of successive initiatives focused
on expanding capabilities with well-defined measures of success identified,
so that progress can be tracked against original intent.
