Global IT giants like IBM, EDS, Accenture and Oracle are gearing up to take on challenges posed by their Indian rivals.A number of global research firms, including Goldman Sachs, Forrester, Gartner, AMR Research and Wachovia Securities have suggested in separate research reports that Indian IT majors are outpacing their rivals in the US as well as other low-cost counties like China.While US tech services firms are likely to post an average operating profit growth of 7% this year, the growth rate is pegged at 22% for their Indian counterparts, Goldman Sachs said in a report.The trend would continue through the next year as well with operating profit growth of US companies estimated a tad better at 9%, with Indians continuing at 22%, the report added.The analysts at the US-based equity research major anticipate an average revenue growth of 30% for the large-size Indian IT companies in 2006 and 2007, as against 8% for their US rivals during the period under review.The industry experts believe Indian IT companies, particularly those in the BPO space, have moved beyond being just low-cost service providers and are focussing more on efficiency and customer satisfaction.Dana Stiffler of US-based AMR Research said in a recent report on the Indian IT sector that the latest quarterly results of large India-based service providers show impressive performance across industries and all horizontal practice areas.
