Expert Analysts on SOA

"By 2008, SOA will provide the basis for 80% of new development projects. By 2008, SOAs will enable organizations to increase code reuse by more than 100%."

"By 2010, 80% of application software revenue growth, including licenses and subscription fees, will come from products based on SOA."

"...the difficulty and cost of modifying today's rigid IT architectures, dominated by big enterprise applications such as ERP, can be so high that some companies would rather abandon new strategic initiatives than make a single change to the applications they already have in place. Good news is on the horizon in the form of service-oriented architectures, which promise to reduce, if not remove, the current obstacles."

"SOA is becoming increasingly widespread and will form a major part of application portfolios by 2010."

"By 2010, at least 65% of large organizations will have more than 35% of their application portfolios SOA-based, which is up from fewer than 5% of organizations in 2005. In 2006, lack of working governance mechanisms in midsize to large (fewer than 50 services), post-pilot SOA projects will be the most common reason for project failure."

"How do businesses need to implement SOA? The change is clear; you must begin to re-architect your IT organization around services and start your IT organization's incremental transformation to support business objectives while making business processes central to your IT organization's design processes."

"Gartner's Position: SOA will shift developer focus from software functions to business functions, thereby transforming installed software from an inhibitor to a facilitator of rapid business change. Realizing these benefits will, however, require increased investment in software, infrastructure, skills, and business process change. SOA will become the dominant framework for creating and delivering software, shifting value from packaged software to subscription services, and from monolithic suites to composite applications."

"Together with the emergence of service-oriented architecture (SOA), application integration is a hot technology, linking business needs to IT abilities; it is certainly a technology to have at the top of your organization's must-have list."

"We project that, by 2009, the proportion of IT budgets spent in-house will decline from the current 48% to 40%. Gartner estimates that the market for IT professional services involving SOA-based Web services was $14.2 billion in 2003. By 2007, this amount will rise to $189 billion, or 1/3 of all IT professional services (which include consulting, development and integration, IT management, and process management)."
