<<ITIL may even pave the way toward better SOA as well. The common
thread between ITIL and SOA was articulated by a post by D.L. Tyler,
who pointed out that ITIL makes it easier to implement SOA:
"Companies look to SOA for lots of reasons, to integrate systems,
to create visibility, to standardize on XML, or whatever. Yet, no
matter the purpose of the initiative or the desired end state, I have
found it easier to implement SOA in environments that have ITIL/ITSM.
Remember, SOA is not about Web services, it is about an approach that
creates agility and responsiveness in both IT and business. That
responsiveness to environmental conditions requires monitoring,
reporting, and responding; ITIL/ITSM focuses on just that."
The bottom line: ITIL is all about governance, and SOA needs a good
healthy dose of governance to move to the next level. Helping IT get
its arms around multi-pronged issues such as versioning and change
management can mean making that leap from Just a Bunch of Web Services
(JBOWS) to SOA.
However, one industry observer says ITIL has grown too big, and too
global, for its current home, and is hampered by barriers to entry and
a general misunderstanding in the industry.
RedMonk's James Governor observes, for example, that ITIL is owned by
UK Office of Government Commerce, which charges for ITIL reference
materials. "ITIL has outgrown the OGC. It outgrew the public sector,
and the UK long ago." Governor added an update that indicates that
things may be improving on this front, as British Standard 15000 on IT
Service Management, "which is aligned to ITIL, is being adopted as an
international standard, ISO/IEC 20000, and future maintenance and
development will be by an international working group."
ITIL is also encumbered by the fact that it is delivered as a whole
library of books, meaning it has two barriers to participation cost
and word length. "Isn't the fact ITIL comes in a bunch of big books a
barrier enough, without introducing fees over a hundred bucks for one
of them? Who ever reads a bunch of documentation-style writing these
days anyway? We want small chunks of relevant content.">>
