A couple of areas that seem to tie into this
- services arguably denote "smaller", well-defined
deliverables. If companies organized their projects
according to expected revenue / cost-savings of a
service, and also delivered them incrementally, there
are big financial implications on cash flow and
working capital. This doesn't really 'require' SOA,
though I think it's definitely useful that there's an
architectural appraoch that complements agile delivery
methods.
- composing activities (human and/or automated)
together with scripting languages & services-oriented
BPM tools can reduce lead times (elminate waste) and
also make "continuous improvement" / kaizen more of a
reality (work standardization through 'standard
contracts')
The area that I'm curious about is how to handle
continuous (over time) changes in service granularity,
which would be the real test if SOA can help Lean
procesess out. There are interesting discussions to
be had on how to track & tear dependencies, isolate
others from these changes through extensibility &
versioning, etc.
This challenge is partly why I find REST so
fascinating, in building robust operations that can
withstand evolution fo the data representations
underneath. The area I'm not quite sure I agree with
is how to evolve the representations themselves,
especially when we're dealing with structured data.
We've never really had a good answer to this (build
another view, in the relational world -- add another
tag, in the XML world).
I hear REST advocates discussing the pervasive use of
RDF topic maps, but in my world they never really were
considered, and aren't likely to be. XML Schemas seem
to be the approach du jour, though their versioning
and extensibility techniques are awfully complicated.
I'm curious how and when we as an industry will
address that.
Cheers
