show consistent growth through 2013, when the revenue will total $16 billion
for enterprise applications.

"The adoption of SAAS continues to grow and evolve within the enterprise

and service availability have diminished for many organizations."

characterized by horizontal applications with common processes, used by
distributed virtual work force teams and within Web 2.0 initiatives.

According to Gartner, office suites and digital content creation are the
fastest-growing markets for SAAS. Office suites are projected to total $512
million in 2009, up from $136 million in 2008. Digital content creation

Gartner says the adoption of SAAS ERP and supply chain management (SCM)
varies based on process complexity. Gartner adds that SAAS is expected to
represent only about 1 percent of ERP manufacturing and operations revenue, but
more than 18 percent of human capital management (HCM)
and 30 percent of the procurement segment by 2013.

Overall, SAAS accounted for more than 18 percent of the CRM
market total revenue in 2008, according to Gartner.

Gartner says factors that impede adoption of SAAS include concerns about data
security, a perceived lack of competitive differentiation, increasing concerns
about scalability and questions about vendor longevity.
