LG CNS claimed it has launched the world's first parallel verification solution “PerfecTwin” that verifies newly constructed IT systems by using actual transaction data.

LG CNS announced on Dec. 17 that it has launched the world's first parallel verification solution “PerfecTwin” that verifies newly constructed IT systems by using actual transaction data.

The solution enables real-time judgment of failures by capturing real transaction data of an existing system and automatically applying them to a new system for a test. PerfecTwin is the world's first solution that supports comparison and verification based on high volume real transactions, LG CNS says


Since the solution uses real transaction data, more than 99 percent of obstacles that can occur after opening an IT system are blocked in advance. It can also save cost and time compared to traditional verification methods. By reducing manual testing by half and human resources by 20 percent, a test alone can reduce overall project costs by more than 10 percent.

Companies usually verify performance, security, and usability of a new IT system before opening it. It is common to screen key features, create scenarios, and test with virtual data. However, many unexpected failures tend to occur in places not defined by scenarios after the opening of the new system. The larger a project is, the more possibility of a failure there is, which can result in putting nearly half of total development cost into testing.

By applying the parallel verification solution to an actual project, LG CNS proved its efficiency. The company quickly stabilized the system by applying it to next-generation projects of the financial sector including those of Kyobo Life, NH Nonghyup Card and KB Kookmin Card which launched related services in September of this year.

In particular, NH Nonghyup Card verified 100 million actual approved transactions in three months. It was not possible to do that by using old test methods. The transaction approval rate which was only 93 percent three months before opening, jumped to 100 percent in one month. LG CNS finished Korean patent application for the solution and launched it in Korea first this month. The company plans to register its patents in the United States, China, and Germany and target overseas markets.
