If you read the fine print in my blog post, you'll see that I qualified my assertions of failure -- "at least in most organizations". I also indicated that organizations that embraced SOA as part of a larger transformation effort often attained spectacular results -- typically in less than 24 months. I have yet to encounter a spectacular success story that did not adopt SOA as part of something much bigger. So I reiterate: if you want spectacular results, you must make a spectacular commitment to change. I contend that this is not a SOA success story -- it is an IT transformation success story.
