In an HP whitepaper, different approaches to Web services orchestration are described. I'm not really sure what to think about this. The question that puzzles me most is this: Do we really need standards like this? Is the combination of Web services really something that should be done any differently than the development of a new service or the wrapping of an existing system?

Phrased differently: Isn't it much more efficient to use some sort of scripting language to tie together several Web services to build a larger one?
