IBM Software Group | Web. Sphere software What is the top focus of businesses? § 75% of CEOs place a high or very high priority on the ability to respond rapidly § Only 1 in 10 CEOs believe that their organization has the ability to be very responsive to react to changing market conditions Source: IBM Global CEO Survey, Feb 2004 “'We are being told that flexibility in business will be more important than operational efficiency. Overall, 62 per cent of respondents believe that we might be arriving at another age where we see the demise of some forms of business because they could not adapt fast enough. ” –Bryan Glick, Computing 21 Sep 2004 6 _ © 2005 IBM Corporation

IBM Software Group | Web. Sphere software What differentiates SOA from claims like this in the past? Standards § Broadly adopted Web services ensure welldefined interfaces. § Before, proprietary standards limited interoperability Organizational Commitment § Business and IT are united behind SOA (63% of projects today are driven by LOB)* § Before, communication channels & ‘vocabulary’ not in place Degree of Focus Connections Level of Reuse § SOA services focus on business-level activities & interactions § Before, focus was on narrow, technical sub-tasks § SOA services are linked dynamically and flexibly § Before, service interactions were hard-coded and dependent on the application § SOA services can be extensively re-used to leverage existing IT assets § Before, any reuse was within silo’ed applications *Source: Cutter Benchmark Survey 10 _ © 2005 IBM Corporation
