How would you describe the following situation? An insurance carrier has a mainframe legacy system that is anywhere from 20 to 30 years old and is written in technologies for which the skill pool is rapidly diminishing. Over the next decade such a scenario will become a crisis in the insurance industry, according to Rod Griffin, director of insurance systems for WorldGroup Consulting. A lot of the old systems really are struggling to meet business demand because of the inherent design restrictions they have, he says. A lot of the [old systems] arent even real time across the board.

Larry Erb, CIO of ING Re, doesnt believe mainframe systems are the culprit because they are still doing the job in a number of companies, particularly for those with high transaction-volume processing. But he agrees with Griffin that legacy systems are reining in future growth. Our legacy systems were a constraint on business growth and required increasingly expensive IT support, he says. Those were the driving forces behind ING Res legacy replacement project.
