About Client
A large financial services organization with data scattered across 8 business units – retail banking, wealth management, insurance, lending, and more. Each unit operated independently, with its own data warehouses, definitions, and tools.
- No enterprise-wide visibility into existing data assets
- 24 redundant data silos identified once discovery began
- Data definitions varied across units
- AI initiatives took months to launch because data discovery and preparation started from zero each time
- Governance was nonexistent
- Conducted comprehensive data discovery across all 8 business units
- Analyzed usage patterns, business value, and duplication
- Identified 24 redundant data silos
- Designed a unified cloud-native lakehouse architecture blueprint that brings all enterprise data together
- Established common data definitions and governance frameworks across business units
- Built a data roadmap with clear phases: foundation, consolidation, AI enablement, and advanced analytics
- Enabled self-service access to trusted data for AI teams, cutting model deployment time in half
- Discovery phase used AI-assisted data profiling to automatically identify duplicate datasets and inconsistent definitions.
- The lakehouse architecture is designed for AI – supporting structured and unstructured data, real-time streaming, and ML model training.
- Data pipelines were architected to serve both BI and AI workloads, eliminating the need for separate copies.
- Governance frameworks include automated data quality monitoring and lineage tracking.
