More than 95 percent of organizations expect to maintain or grow their use of software as a service (SaaS), according to a survey by Gartner, Inc. Survey respondents cited significant integration requirements and a change in sourcing strategy as the top two reasons for adoption followed by high total cost of ownership (TCO).

Still, Gartner found that most companies still do not have policies governing the evaluation and use of SaaS with only 39 percent of respondents indicating that such a policy or process exists, up just 1 percent from 38 percent in 2008.
