Case Study: Siemens Healthineers achieves global supply chain optimization and rapid analytics with Snowflake

Siemens Healthineers Optimizes Business Operations Around The Globe

Siemens Healthineers, the global medical‑technology company based in Erlangen, needed a new data infrastructure to support a supply‑chain control tower and broader digitalization goals. Their legacy, centrally managed data lake struggled to scale for multi‑regional use, causing performance bottlenecks, governance challenges, and limited access to master and operational data across departments and entities.

By migrating to Snowflake on Azure and implementing a data‑meshed architecture, IT created globally distributed data lakes with centralized management, easy cross‑region sharing, and flexible, isolated compute for use‑case workloads. The change cut complex query and extraction times from hours to minutes, reduced maintenance and costs (an ETL unload of a 260‑column, 3M‑row table runs in ~6 minutes), enabled same‑day CRM access after an acquisition, and empowered analytics, automation, and improved supply‑chain KPIs.
