India's fourth largest software exporter, HCL Technologies is charting out a non-linear growth strategy for its BPO arm that would help the company hedge against currency fluctuations, published media reports have said.

HCL BPO employs 13,000 people and contributes about 12 per cent of the company's revenues since its inception seven years ago and is considered to have one of the best operating margins in the industry, a report in DNA Money newspaper said.

It quoted Ranjit Narasimhan, COO of HCL Tech BPO Services as saying that a linear model would mean having 60,000 people on the rolls which would mean adding 3,000 people and interviewing 36,000 every month just to sustain that level, something that is not sustainable.

So, instead of recreating from scratch, the company has gone in for overseas acquisitions, outcome-based pricing, scalable platforms and English-speaking workforce, the paper quoted Narasimhan as saying.

He concluded that within two years from now, more than fifty per cent of their deals would move to outcome-based pricing while the non-voice part of the business would grow at the cost of voice-based activity so that within two years these would contribute equally to the business instead of the 70 to 30 ratio in favour of voice that the company currently holds.
