SOA is a disruptive technology and as such it is important that people,
especially IT, change their perspective. I ran a development group at
Hitachi in which we were changing our focus to Web Services, not even
SOA. My biggest problems came from the best and most senior engineers.
These people had developed expertize in procedural programming and had
applied that knowledge to highly distributed systems. Getting them to
make the mind shift to SOA was equivalent to getting a person to change
religions. To my discredit, I was not successful in getting the top
engineer to change. Sigh!
Note that the author of the referenced article picked as the best
definition of an SOA one from the WIKI, which was technology biased.
Unfortunately, I believe that his business audience accepted his
definition because they concluded "This is just another one of those
technological thingees, so lets move on". In other words they didn't
buy it and another group was lost. We need more evangelizing as
distasteful as it might be.
You and Frank are great at explaning an SOA. Consequently, I propose
that you put a more accurate definition on the WIKI.
Here's a business manager oriented, not RM although derived from the RM
concepts, definition that I have be thinking about.
"An SOA is a business approach that enables the wide-spread sharing of
business processes to satisfy business requirements, whether the sharing
parties are in the same business unit, spread across the organization in
different departments or divisions, or even in different companies."
(Maybe business requirements should read business needs)

Obviously, we tried to say a lot (maybe too much) and didn't consider
the need for an elevator speech.
