“Improve end-user productivity and convenience by tying together heterogeneous systems so that application silos disappear while underlying processes and data become visible”

What others have said
About standards, not about infinite choice (Walsh, 2002)
Seductive but fuzzy, the next evolutionary step (Oblinger, 2002)
Most promising aspect is ability to resolve differences among shared networked applications (Jacobson, 2002)
The capabilities of Web Services will expand and a new generation of service applications will emerge –designed and built by business integrators, not programmers. (Gleason, 2002)
