Case Study: Nationwide Mutual Insurance Company achieves enterprise-wide customer insights and data-driven growth with Teradata

Nationwide Financial - Customer Case Study

Nationwide Mutual Insurance, a large, 85‑year‑old Fortune 500 insurer, faced a fragmented, “stovepiped” data environment across dozens of legacy systems and autonomous business units that slowed reporting, obscured a unified customer view and complicated mergers and pricing decisions. The company needed a single, authoritative data platform to improve customer insight, speed decision‑making and drive revenue growth while cutting costs.

Nationwide implemented an enterprise data warehouse on Teradata and built solutions including the Customer Knowledge Store, Financial Performance Management, Goal State Rate Management and Revenue Connection to consolidate 200+ source systems and years of policy history. The work delivered a unified customer view and faster, accurate reporting (monthly close cut from 14 to 7 days), real‑time dashboards (reports in 4–45 seconds), improved retention and >3% incremental annual sales from CKS, projected 5% pre‑tax operating cash‑flow improvement from GSRM, 20–30% productivity gains in some units, and significant IT and cost reductions.
