Case Study - Self-Service BI for a Conglomerate with Luce

Executive Summary

In June 2026, We implemented a self-service BI solution for a large conglomerate, eliminating IT bottlenecks and empowering 500+ business users with direct data access. The project leveraged modern data stack technologies to achieve materially faster report generation and a meaningful reduction in IT support requests, establishing a scalable, user-friendly BI platform.

The Challenge: IT Bottlenecks for Business Users

The conglomerate faced significant challenges with their existing analytics infrastructure:

IT Bottlenecks

• Request Backlog: 200+ pending analytics requests with 2-4 week turnaround times
• Resource Constraints: Limited IT resources for ad-hoc reporting needs
• Knowledge Silos: Only IT team had access to complex data models
• Slow Response: Business users waiting weeks for simple data requests
• Escalation Delays: Complex requests requiring multiple IT team members

Business Impact

• Decision Delays: Critical business decisions delayed due to data unavailability
• Opportunity Loss: Missed market opportunities while waiting for reports
• Productivity Loss: Business users spending 40% of time on data requests
• Competitive Disadvantage: Slower response to market changes
• Frustration: Business users unable to explore data independently

Technical Constraints

• Complex Data Models: Multiple data sources with inconsistent schemas
• Access Control: Limited user access to raw data sources
• Performance Issues: Slow query response times for complex reports
• Governance Gaps: No standardized data definitions across business units
• Security Concerns: Direct database access posing security risks

Solution: Self-Service BI Platform

We implemented a self-service BI solution using modern data stack technologies:

Technical Stack

• Cube.js: Semantic layer for business-friendly data access
• DBT: Data transformation and modeling layer
• BigQuery: Cloud data warehouse for centralized data
• Looker: BI platform for visualization and exploration
• Apache Ranger: Fine-grained access control
• Terraform: Infrastructure as Code for deployment

Self-Service Architecture

Our self-service BI architecture follows a semantic layer approach with business-friendly data models and controlled access, enabling business users to explore data independently while maintaining governance and security.

Measurable Results

Performance Improvements

Before Implementation

• Dashboard Load Time: 10-15 seconds for complex reports
• IT Request Turnaround: 2-4 weeks for ad-hoc requests
• User Dependencies: 100% reliance on IT for data access
• Data Exploration: Limited to predefined reports
• Decision Speed: Delayed due to data unavailability

After Implementation

• Dashboard Load Time: 2-3 seconds for all reports
• Self-Service Access: 80% of requests handled independently
• User Empowerment: Direct data exploration capabilities
• Real-time Analytics: Live data access and exploration
• Faster Decisions: Immediate access to business metrics

Business Impact
