Case Study: a leading specialty insurer speeds rating updates with Coherent Spark

Leading Specialty Insurer launches rating updates in 90 days with Coherent

A leading specialty insurer faced challenges with its rating logic residing in Excel, which required slow, manual IT intervention to implement updates into its OneShield policy administration system. This process delayed product launches and added operational overhead. To address this, the insurer partnered with Coherent to find a faster, more transparent way for business users to manage changes without increasing system risk.

Coherent implemented its Spark product, which automatically converted the insurer's Excel-based rating logic into fully functional APIs that connected directly to OneShield in real time. This solution gave business users control of updates within the familiar Excel environment while maintaining IT governance. The results included a successful pilot to production in just 90 days, a significant reduction in manual steps, and a scalable path to modernize additional products and business lines.
