Service Reuse... What are reasonable expectations?

Today's ebizQ discussion on the SOA forum is around service reuse. To me, this is deja vu all over again. I remember this same discussion about libraries, procedures, objects, and components. Now it's about services.

In my opinion, service reuse is the wrong metric to be tracking with SOA. In addition to be being very subjective, it's a very tactical metric akin to saying that an "enterprise is secure because our firewall has no known vulnerabilities." While an amusing statistic, service reuse is not why an SOA should be implemented, nor is it the proper way to justify it. Then what makes the business case for SOA? That would be a tangible, demonstrable alignment to organizational and business objectives.
