Regulatory compliance concerns also inhibit SOA adoption. "They are quickly realizing there's this notion of rogue services, with people publishing services all over the place that people can use."
Information industries like finance and insurance are moving more quickly to SOA than physical goods industries such as manufacturing. Information industries tend to use more home-grown software and less packaged software from the likes of SAP and Oracle, Saxena said. Those packages aren't necessarily less flexible but customers tend to be tied to the vendors' release cycles, which affects the timing of new projects, he said.
Europe has caught up considerably to the U.S. in its SOA adoption, according to Saxena.
IBM also introduced services to help customers figure out where they can get the most value from integrating processes, how far along the road they are today and what tools and services they can use. IBM encourages customers to begin with small projects, and typical engagements are four to six months, Saxena said.
IBM sees five levels of SOA readiness from "ad hoc" through "aware" to "world class." He estimated that most Fortune 1000 companies are between levels one and two, although a company may be more advanced in a particular area like IT systems.
Wednesday's releases are the first of several SOA announcements IBM will make in the coming weeks, targeting companies at different stages of SOA development.
