Computer Systems Corporation (CSC) is losing further ground to its competitors as more companies switch to more effective systems.
Zurich Financial Services (ZFS) is the latest major insurer to defect to another system company.
David Smart, director of business development at Insurance Services Office, which developed the Claims Outcome Adviser (COA) personal injury claims management solution, said ZFS has selected its package over CSC's Collosus.
"There has been a need for Collosus in the past but requirements have now changed. More people are looking at COA to address their needs now."
Major companies such as Highway Insurance and ZFS are now using the package and Highway has lauded it "a real success", he said.
Zurich selected COA following a pilot and in depth cost-benefit analysis of the solution.
Roger Day, managing director of group claims for Zurich said: "COA's advanced management tools will provide us with information and a level of control of our claims portfolios that we haven't previously had."
According to Smart, Collosus had 60% of the market volume at one time, " but it was written in the technology of 15 years ago.
"Technology has moved on now. It is important to keep software fresh and regularly updated. COA is continually being updated," he said.
Smart attributes COA's success to it recognising movement in the market and enabling people to become more proactive in personal injury claims.
"COA identifies ways of ensuring the best outcome on a claim," he said.
