One challenge I've seen around the "reuse" question is that IT folks think about reuse and business folks thing about "use". People don't "reuse" finance or procurement, they "use" it. Now how do you get people to agree to a central procurement shared service (business concept) rather than departmental procurement operations? The answer is that you have a business change programme to drive that behaviour home.
How many SOA programmes have a business change programme as an integral part? Is their a correlation between the lack of business change and the lack of reuse, or use? I'd bet heavily on yes. My personal view is that re-use isn't the goal, its "use" but unfortunately in IT we can do the down loading of a library that the first requires but rarely can we do the business change required for the later.
