Reinsurers today face mounting pressures – from increasingly severe catastrophes and regulatory demands to legacy systems that impede speed and accuracy. Traditional systems of record and engagement are no longer sufficient, as they merely store and display data without enabling action. Insurance core technology and surround systems often plateau at generating dashboards that still depend on someone to act. Reinsurance enterprises today have no shortage of insights but a scarcity of human and AI agents and a system capable of executing on them. SoA fill this gap by ingesting data, applying AI-driven analytics, and autonomously initiating decisions across the value chain. The report outlines how SoA can fundamentally reshape core reinsurance functions such as catastrophe modeling, underwriting, contract administration, technical accounting, and claims management. By embedding SoA, reinsurers can move from manual, reactive processes to intelligent, real-time operations. Benefits include faster decision-making, reduced costs, improved claims accuracy, and enhanced risk responsiveness. In addition to outlining technology and operational changes, the report emphasizes the strategic role of CIOs and COOs in driving SoA adoption. It urges leadership to align stakeholders around business outcomes, invest in data readiness, manage organizational change, and maintain a focus on measurable value. A future-state reinsurer enabled by SoA is envisioned as agile, intelligent, and resilient; capable of adapting instantly to risk events and market shifts. Everest Group concludes that embracing SoA is no longer optional; it is a strategic imperative for reinsurers looking to lead in an increasingly complex and competitive environment.
