The outsourcing industry regained its strength in the last few months with some companies preferring to move their jobs to leading destinations such as India, China, Costa Rica and the Philippines, a research showed.

According to a study by PriceWaterhouseCoopers, outsourcing is back on track after a few years when companies still opted to reduce jobs rather than moving them.

The Economic Times of India quoted Charles Aird, PWC Managing Director for shared practices, as saying that the biggest factor being considered is cost although people are still in search of higher quality and greater efficiency.

There is also a growth in the list of services being outsourced. ET quoted Forbes as saying that not everything could be effectively outsourced.

For example, Dell eventually sent back its call center support services to the US from India, which has had a reputation of “alienating” clients’ customers; while rival Apple persistently kept its support services within the country wherein calls come from.

Meanwhile, other services, including application development, have shown to be greatly successful in India’s outsourcing industry.

Aird also added that it is important to have the sourcing strategy tied to the business strategy, since the company may be endangered when it outsources some of its core services.

Also, outsourcing now becomes diverse in terms of the language being used. India, which is the original and biggest outsourcing destination, is mainly tied to English-speaking countries, while countries like China and Poland are advancing their training of outsourcing skills for non-English speaking markets.
