From Web Services to SOA and Everything in Between: The Journey Begins Highlights - WebServices.Org

A pretty detailed report:

From Web Services to SOA and Everything in Between: The Journey Begins Highlights - WebServices.Org: "The survey found that while there are relatively few advanced Web services sites � and even fewer bona fide SOA implementations � managers and executives clearly understand the value proposition this new architecture has to offer. A large number of respondents are currently either deploying simple interfaces, or have new projects under development, the survey finds. Most businesses that do have efforts underway report they are seeing tangible benefits in terms of reuse, developer productivity, and cost savings.

The survey found that 35% of businesses have or plan to have a fully functioning Web services infrastructure in the near future. At this point, about 18% can be considered �SOA-ready,� meaning they are part of an infrastructure of standardized, loosely coupled services. For most companies, the hard work still lies ahead. About 24% have simple point-to-point implementations, and 29% are still in the development stages. "

This is a major trend with extreme potential for cost reductions, and its within a stone's throw of reaching critical mass.
