Frost & Sullivan attributed the growth to the focus of enterprises on customer service. Industry-wise, the growth is coming from telecommunications, and banking and finance sectors. Location-wise, domestic demand is fuelling the growth, the news analysis noted.

"The intensifying focus on quality customer service has piqued the interest of domestic enterprises, which has, in turn, raised the level of competition in emerging markets," said Frost & Sullivan. "Customer service enhancement continues to receive priority, as enterprises are investing more capital in contact centres that offer superior client satisfaction."

All, however, is not well looking into the future. Frost & Sullivan warned of saturation and high attrition.

While all emerging markets are expected to maintain double-digit growth, the rapid growth will result in market saturation. Already, Frost & Sullivan has noted that countries such as Singapore, Hong Kong, and Taiwan are already "showing signs of saturation and are on the higher end of the growth curve."

And success has its price. In the case of the contact centre industry, Frost & Sullivan warned that the attribution will increase due to high stress levels in the industry and other career prospects in other industries.
