Enterprise Knowledge Search · Real-time Analytics

Vodafone needed to give data-center engineers faster access to performance metrics, inventory information, and technical documentation without forcing them to rely on custom dashboards, manual SQL, or slow document searches during incident response.

Reported impact

Business outcome

Vodafone reduced time-to-insight for infrastructure issues, gave engineers dynamic access to metrics and documentation without custom dashboards, and created a modular agent architecture that can expand to new domains and data sources.

  • Scalability

Solution

Vodafone built two internal assistants on Google Cloud for engineering and operations teams across its data centers. Insight Engine uses LangGraph to route natural-language questions into an NL2SQL workflow that queries monitoring and inventory systems, then hands results to downstream chains that generate charts and other visualizations. Enigma uses LangChain document loaders, model abstractions, and a multi-vector DB to ingest HLDs, blueprints, RFPs, and SharePoint content into RAG pipelines so engineers can retrieve grounded answers, design details, and contacts. LangGraph coordinates the modular agents, query-processing steps, and API integrations, letting Vodafone expand the system with data collection, processing, and report-generation modules while benchmarking different LLMs for each use case.

Data flow

An engineer submits a natural-language question, LangGraph classifies the intent, and either sends the request to Enigma for RAG over the multi-vector DB and SharePoint content or to Insight Engine for NL2SQL over monitoring and inventory systems before results are returned as summaries, tables, or charts.

Solution architecture

7 components · 4 layers
  1. Compute
    • Google Cloud Hosts the internal assistants that support data-center engineering and operations teams.
  2. Storage
    • multi-vector DB Stores document representations and retrieval context used by Enigma.
    • inventory DB Stores inventory records that the Insight Engine queries and visualizes.
  3. Serving
    • Insight Engine Answers natural-language questions about performance metrics and inventory data for engineers.
    • Enigma Provides grounded retrieval over technical documents, designs, and organizational contacts.
  4. Orchestration
    • LangChain Supplies document-loading, model-integration, and RAG building blocks for the assistants.
    • LangGraph Interprets user intent and orchestrates the correct chain or multi-agent workflow.

Architecture clues

  • Insight Engine can transform natural-language queries into SQL, NoSQL, and other structured requests.
  • LangGraph sits after the user prompt to route requests into the correct chain.
  • The assistants are deployed on Google Cloud.
  • Vodafone benchmarked multiple LLMs across the pipelines for different use cases.

Evidence from the source

LangGraph is placed after the user prompt where it will understand the intent of the user query and orchestrate the request to the appropriate chain.

Scoring methodology

How scores are calculated

Customer Reference Value measures usefulness as a customer reference. Evidence Confidence measures the quality and traceability of available evidence, not independent verification.

Customer reference value75/100
  • Problem clarity20/20
    Measures whether the customer's operational problem is specific enough to compare.
  • Implementation depth25/25
    Rewards named components, data flow, integrations, and architecture detail.
  • Outcome specificity20/20
    Measures whether the reported benefit is concrete rather than a generic claim.
  • Quantified impact0/25
    0 metrics describe measurable impact.
  • Deployment scale10/10
    Rewards evidence of a live or scaled deployment and meaningful integration scope.
Evidence confidence87%
  • Source authority20/25
    The main evidence is an official vendor-published customer story.
  • Claim traceability21/25
