India's business process outsourcing companies could attain revenues of up to £25bn by 2012, but the industry will need greater investments in education and infrastructure by the government, according to a report.

At its current growth rate, India’s £5.5bn BPO industry will reach about £15bn by 2012, said the joint report, published by consultancy firm Everest Group and India’s National Association of Software and Services Companies (Nasscom).
