Overview
Birlasoft partnered with a leading North American P&C insurance carrier to modernize its legacy Policy Administration System (PAS). This engagement went beyond a traditional QA program—it was a QA-led transformation initiative, where quality engineering was embedded across the modernization lifecycle.
The legacy PAS had evolved into a highly complex ecosystem supporting 30+ Lines of Business (LOBs) and 150+ product codes, managing rating, policy issuance, document generation, and full transaction processing. While critical to operations, the system increasingly limited business agility and scalability.
A critical requirement of the transformation was to ensure that the modernized system maintained complete behavioral consistency, where even minor deviations in calculations or business logic could impact premiums, customer experience, and regulatory compliance.
Key Challenges
Modernizing a large-scale legacy PAS required addressing multiple layers of complexity:
- Behavioral Consistency: Ensuring identical business outcomes between legacy and modernized systems
- Undocumented Business Logic: Capturing and validating years of implicit and explicit business rules
- Document Complexity: Validating over 20,000 documents for layout, rules, and data mapping accuracy
- Risk-Controlled Rollout: Enabling phased deployment with minimal disruption to business operations
- Post-Go-Live Assurance: Delivering sustained stability and confidence beyond traditional support models
Birlasoft Approach
Birlasoft led the QA program with a risk-based, transformation-aligned approach, ensuring the modernized platform accurately replicated legacy behavior while enabling controlled enhancements.
The program was structured into two delivery phases:
- Core rating functionality (highest risk)
- Policy lifecycle, UI, documents, and integrations
QA was initiated upfront to define parity expectations, identify high-risk areas, and design comprehensive test coverage.
Core QA Capabilities Delivered
Functional Parity Testing
Identical scenarios were executed across both legacy and modernized systems to ensure consistent outcomes across all LOBs and products. Every deviation was analyzed and validated with business stakeholders.
Document Conversion Validation
Over 20,000 documents were validated for layout accuracy, business rules, and data mapping, with focused testing on complex areas such as Manuscript Endorsements and Automatic Renewals.
Automated Regression at Scale
Automated test suites enabled repeatable, high-frequency validation across releases, ensuring stability across interconnected LOBs and product combinations and reduced risk of downstream defects during iterative development.
Integration & Performance Testing
End-to-end validation ensured seamless data flow across upstream and downstream systems, while performance testing confirmed readiness under peak business conditions. It ensured that modernized system exceeded legacy benchmarks.
Phased Rollout & Hypercare
A feature-based rollout minimized risk through controlled deployment. During the 120-day hypercare phase, every issue was root-caused and validated—resulting in zero defect leakage which significantly improved business confidence and adoption.
Business Impact
- 30+ LOBs fully validated with end-to-end QA coverage
- 150+ product codes tested for functional parity
- 20,000+ documents successfully converted and validated
- Zero defects at go-live
- 120-day hypercare with 24×7 QA-backed support
Outcome
The modernized PAS went live with zero defects, enabling a seamless transition and rapid business adoption. By embedding QA into the transformation lifecycle, Birlasoft ensured stability, minimized risk, and built lasting business confidence.
