Good stuff Stefan. I concur that development cant be separated. My declaration that SOA Lifecycle and SDLC (Software Development Lifecycle) are "completely" seperate is specious and you are right to point that out.
The reason why I put it strongly is to raise the point that SDLC and the lifecycle of a service are at different levels of granularity, and that "Software" mostly is concerned with what's under the interface and "Service is mostly concerned with what's up top. I say "mostly" because of the fundamental inseperability of interface from implementation which I lampoon in the "Pizza Shop Blueprint" http://www.soacenter.com/?p=33 I really appreciate the distinction you're making, as I see people making the mistake that SOA Lifecycle = Software Development Lifecycle, and probably overcorrected by going in the opposite direction. The truth, as in most cases falls in between, you are right to point this out. It gets interesting when you put policies into a lifecycle, but I'll leave that for another conversation...
