Several years ago, India received about 80 percent of all U.S. offshore spending, but that percentage has since declined to about 59 percent as offshore development becomes more global, according to Frances Karamouzis, an analyst at Gartner Inc. U.S. firms now spend about US$26 billion a year on offshore IT services outsourcing, she said.

The Philippines accounts for about 9 percent of the total spending by U.S. companies; Canada and Brazil receive about 8 percent each; Central and Eastern Europe, 7 percent; Mexico, 4 percent; and China, 3 percent.

"There will be an evening out of distribution across different countries," said Karamouzis, who believes that the motivation for doing so won't be based on a search for lower labor costs, but around the need for specific IT expertise as well as follow-the-sun delivery. "I think India is not going to be in the position to say, 'We can do everything,'" she said.

Other regions such as Eastern Europe are unlikely to rival India in size because they don't have the population -- but they may appeal to companies seeking specific skills, said Karamouzis. One company that has had experience with Eastern European IT labor is CareFirst BlueCross BlueShield in Owings Mills, Md. It has been using Epam Systems Inc., a Lawrenceville, N.J.-based company that primarily delivers offshore services from Russia and Eastern Europe. It has about 2,300 employees.

Maynard McAlpin, vice president for strategic planning at the insurer, said that many of Epam's workers have engineering and science degrees, which he believes has added to the quality of the development work. "I used to think that any Java developer is a Java developer. But what I found is there is a huge difference between someone who is a developer and someone who does engineering," said McAlpin, who added that the developers have taken on some complex work. "We had some tricky things for them to figure out," he said.
