Enterprise Data Lake-led Ecosystem Empowers Self-service Insurance Analytics

Read | Jul 14, 2025

A WNS Perspective

Key Points

  • A leading insurance provider faced significant reporting inefficiencies and data fragmentation across underwriting, claims and business operations.
  • WNS Analytics implemented a cloud-native enterprise data lake using Microsoft Fabric to unify data, automate integration pipelines and embed self-service analytics through Power BI and Copilot
  • The solution enabled a 40 percent reduction in reporting time, 35 percent increase in data access efficiency and empowered business users with self-service analytics, laying the foundation for future-ready, insight-led insurance operations.

The Industry Landscape
Evolving Trends in Insurance Analytics

Legacy systems and fragmented data continue to hinder fast, intelligent decision-making in insurance. With growing data volumes across underwriting, claims and compliance, insurers must modernize their data foundations to enable agility, personalization and regulatory alignment.

Intelligent data architectures that combine cloud-native platforms with human-led design are re-shaping the landscape, turning real-time, self-service analytics from a competitive advantage into a business imperative.

The Client Challenge
Fragmented Systems, Limited Insights

The client recognized that its legacy business intelligence infrastructure was constraining growth and limiting competitive agility in an increasingly dynamic market.

Critical pain points included:

1. Data Fragmentation and Third-party Dependence

The organization relied heavily on off-the-shelf reporting solutions that provided limited flexibility beyond pre-configured insights, creating bottlenecks for custom analysis and strategic planning.

2. Operational Inefficiency

Lack of policy system integration and limited data availability resulted in lengthy report generation cycles, delaying critical business decisions and reducing responsiveness to market opportunities.

3. Scalability Constraints

With existing Business Intelligence (BI) assets requiring rationalization, the client faced mounting maintenance costs and declining system performance that threatened long-term sustainability.

4. Limited Self-service Analytics

The absence of intuitive self-service analytical tools restricted business users' ability to explore data independently. They were unable to generate ad-hoc reports or derive timely insights on their own. As a result, they became excessively dependent on specialized IT and data analytics teams for routine business intelligence needs.

5. Manual Reporting Dependencies

A substantial portion of the report generation workflow required extensive manual intervention, introducing inherent inefficiencies, elevating the risk of human error and prolonging turnaround times for critical business reports.

6. Fragmented Report Versions

Multiple versions of key reports existed across departments, often without harmonization. This led to the absence of a single source of truth for critical business metrics. As a result, it fostered confusion, contradictory analyses and diminished stakeholder confidence in data integrity.

To maintain competitive leadership and drive sustainable growth, the client needed to transform its data architecture from a collection of disparate systems into a unified, intelligent foundation that empowered business users while maintaining enterprise-grade security and governance.

The Solution
A Secure and Scalable Data Lake Powered by Microsoft Fabric

WNS Analytics designed and deployed a comprehensive enterprise data lake solution built on Microsoft Fabric’s OneLake platform, harmonizing human ingenuity with next-generation technologies.

Our approach blended domain excellence with data management to deliver a context-aware solution, while Microsoft Fabric's unified platform enabled seamless data integration and intuitive self-service capabilities.

Key elements of the solution architecture included:

1. Metadata-driven Dynamic Data Integration

Harmonized sales, distribution, underwriting and claims data streams through automated pipelines and real-time synchronization

2. Centralized Cloud-native Repository

Implemented Microsoft Fabric OneLake as a unified, cloud-native data foundation, integrating domain-specific metadata, end-to-end lineage tracking and advanced data governance

3. Enterprise-grade Security

Implemented a unified data access framework with enterprise-grade Personally Identifiable Information (PII) encryption and role-based controls, ensuring secure, compliant and collaborative data use across departments

4. Integrated Self-service Analytics Ecosystem

Integrated Power BI with Microsoft Fabric and Copilot to deliver intuitive, real-time dashboards and ad-hoc analytics. Rationalized legacy BI platforms to reduce redundancy, accelerate insight generation and empower business users with secure, self-service access to enterprise data

The Outcome
Enterprise Intelligence Delivered at Scale

The deployment of our intelligent data foundation solution delivered immediate and sustained value. Our strategic thinking, integrated with advanced analytics, transformed data from information into actionable intelligence, enabling the client to make faster, more informed decisions.

The tangible outcomes included:

% reduction in report generation time and cost driven by automated workflows, self-service capabilities and a unified reporting framework

% increase in data access efficiency and accuracy enabled by a unified data architecture with embedded metadata that ensured reliability and real-time access for business users

% decrease in maintenance and licensing costs through reduced solutions complexity and infrastructure overhead by rationalizing 40 percent of legacy BI assets and consolidating platforms

Empowered, insight-driven teams as business users were equipped with intuitive tools for self-service analytics, driving faster, decentralized decision-making

Through this partnership, our client solved immediate operational challenges while establishing a foundation for continuous innovation and market leadership.
