Same Software, New Approach: Lessons from WTW’s Client-Hosted to SaaS Journey

For over thirty years, the Insurance Consulting and Technology business within WTW has been developing innovative insurance software solutions in a traditional client-hosted model. In this environment, the focus was on delivering software packages and updates, leaving deployment and operations in the hands of customers.

Nearly a decade ago, we embarked on this journey - not just as a technological modernisation but as a fundamental shift in mindset, culture, and operational capabilities. Balancing the needs of both SaaS and client-hosted customers, we’ve evolved our approach to deployment, reliability, and continuous improvement.

In this session, Chris Marks, Director of Site Reliability and Response at WTW, will share how the team evolved their operational capabilities, transitioned to SaaS while balancing the needs of client-hosted customers, and turned operational challenges into opportunities for improving application resiliency.

Whether your organisation has been SaaS-native from day one or is currently undergoing its own transformation, this session will provide valuable insights into how we managed this transformation.
