Less than 5% of IT jobs in the United States and other developed countries are currently sent offshore, Gartner says. That number will rise to 30% by 2015. Worldwide spending on offshore research and development and engineering will increase by a whopping 860%, from $1.25 bln in 2004 to as much as $12 bln in 2010, Gartner predicts. Offshore spending on infrastructure outsourcing will grow from between $100 mln and $250 mln to between $3 bln and $4 bln over the same period. Offshore spending on application-development services will more than double from $23 bln to as much as $50 bln.
