"We have lots of J2EE and Java certified programmers, but we still changed to .Net, because we see it as an upgrade to the system," said Hong. "Of course the decision was not agreed to by everyone. But in a constantly changing telco industry, to meet the development time required, we needed a platform that could speed our development cycle."

He explained since the new development environment can achieve business goals better and improves the PCS performance, that's an upgrade.

"For the long-term, this language is the most economic solution for our business needs," he concluded. "We need quality applications to be developed at the shortest time with the least people, .Net comparatively is the best way to go for us.
