GenAI Case Study: Data Assistant
Human Resources Analytics Assistant

How EFS Networks built a natural-language data assistant on AWS that lets non-technical managers self-serve analytics — cutting report creation time by 88% and achieving 4.5x ROI within six months.

Industry: Enterprise Data & Operations Status: Production since Q1 2025 AWS Bedrock • Athena • OpenSearch • QuickSight

Business Challenge

Managers lacked the technical skills to query Amazon Athena or QuickSight directly, causing delays and constant ad-hoc report requests. The analytics team was overwhelmed with routine data pulls, leaving no capacity for strategic analysis.

AWS-Powered Solution

EFS Networks designed and deployed a generative AI data assistant that translates natural-language questions into SQL queries with enterprise-grade security:

  • Amazon Bedrock (Claude 3 Instant) — Natural-language to SQL translation for intuitive data access
  • Amazon Athena + Glue Catalog — Query execution and schema management across distributed data sources
  • OpenSearch Serverless + Titan Embeddings — Semantic context and metadata grounding for accurate query interpretation
  • QuickSight API — Automatic visual summary rendering from query results
  • Amazon Verified Permissions — Row-level security enforcement per user role
  • SageMaker Pipeline — Continuous learning through user feedback ingestion on query accuracy
