Contents

01 Insurance Legacy System Modernization: The Guide 13 min read Insurers run policy admin, claims, billing, and rating on decades-old systems whose rules were never written down. Here's how to modernize them without a big-bang write-off.
02 COBOL in Insurance & the Talent Cliff 12 min read Most insurance cores still run on COBOL, and the people who understand it are retiring on a schedule. Here's the real risk, and how to retire COBOL without a big-bang cutover.
03 Policy Administration System Modernization 12 min read The PAS is the insurer's system of record — quote to bind to renewal — and its lifecycle rules are buried in code. Here's how to modernize it slice by slice without breaking the book.
04 Underwriting & Rating System Modernization 13 min read The rating engine and underwriting rules are an insurer's crown jewels — and its most undocumented code. Here's why recovering them as living specs is the highest-leverage move in modernization.
05 Claims System Modernization 12 min read Claims systems encode adjudication, reserving, and payment rules that hit loss reserves and customer trust directly. Here's how to modernize them slice by slice, with parity proven first.
06 Core Insurance Modernization: Build vs Buy 12 min read Buy a packaged core or build your own? The honest answer for insurers: the build-vs-buy question matters less than how you migrate the undocumented rules and prove parity either way.
07 Insurance Modernization & Regulatory Compliance 12 min read Regulation mandates outcomes, not architectures. Here's what insurance rules actually require of legacy systems, and how rules-as-specs makes compliance easier to evidence — not harder.
08 Parity Validation for Insurance Systems 12 min read On a rating or claims engine, 'looks like it works' isn't a standard you can file against. Here's how parity validation proves a modernized insurance system behaves identically before it goes live.
09 Insurance Modernization Cost & the Business Case 12 min read What core insurance modernization costs, what drives it, and the compounding cost of standing still on a system whose experts are retiring — the business case an economic buyer can approve.
