What the statistics are telling us about SOA

A summary of 2007 SOA surveys

There were plenty of surveys and studies around SOA adoption and issues this past year. Overall, the surveys point to widespread interest in SOA, and results among those companies with SOA already in progress.

Here are a few highlights from this year's studies of SOA adoption:

57% of executives expect to see cost reductions as a result of SOA, while 27% cite code reuse and 23% expect to increase business agility. (Saugatuck)

50% of new mission-critical operational applications and business processes were designed this year around SOA, a number will jump to more than 80 percent by 2010. (Gartner)

40% of companies with SOA spend between 10 and 30 percent of their overall IT budgets on SOA projects. Most have increased their SOA budgets over last year. (IBM)

48% of CIOs are planned to open their SOAs “to the cloud” in 2007 — the cloud being “where their current and potential trading partners are.” (McKinsey)

37% of companies implementing SOA report seeing positive return on investment from SOA -- which, by the way, isn't too shabby (Nucleus Research)

29% of companies with advanced SOA deployments are using SOA governance software, compared of 17% of companies still in earlier stages of SOA. (Aberdeen)

61% of advanced SOA deployers saw a reduction in the number of software defects discovered in production, compared to 18% of non-deploying companies could say they were able to reduce defects. (Aberdeen)

49% of developers working with SOA say they can now complete a typical SOA project within three months – more than twice as many as a year ago. Plus, more than 60% of all SOA projects are now developed and deployed within just six months. (Evans Data)

75% of mainframe users said they want to modernize their systems. But 52%, also said they had concerns about their system’s ability to actually support SOA. (Software AG)

25% of mainframe companies have SOA efforts now in progress, and another one-third are planning or considering SOA. At least half say they are or will employ mainframes in a central role in SOA. (Unisphere Research/SHARE)

55% of executives view SOA as “the best way to support the use of social networking and Web 2.0 development techniques in their IT infrastructure.” (BEA)

56% of executives at companies deploying SOA admit that at least half of the code or artifacts developed under their roofs are not reviewed for compliance before moving into production. (SOA Forum)

15% of small companies (with fewer than 100 employees) have SOA efforts underway, compared to 35% of companies with more than 500 employees. (Nucleus Research)

12% -- that's the average growth rate of companies with "well-aligned IT-business operations," versus 4% overall. (BTM Institute)
