Case Study: Système U achieves faster, more efficient data operations with Looker

Système U Modernizing its data architecture using Google Cloud

Système U, the French retail cooperative with nearly 1,600 outlets, was facing growing data and IT complexity as it modernized its operations. Its U Iris IT division needed a more agile, cloud-based data architecture to support reporting, analytics, and future innovation, and chose Looker as part of its Google Cloud data strategy.

Looker-supported modernization centered on BigQuery, which unified Système U’s data lake and data warehouse into a single platform and simplified how teams worked with data. The result was about a 40% reduction in operating costs, processing up to 95% faster in some tests, and data ingestion times cut from 15 minutes to 9 seconds, with Looker helping enable faster, more flexible access to insights.
