Case Study: Johnson Controls achieves real-time supplier collaboration and inventory accuracy with LeanDNA

Jessica Zhao Drives Agility and Supplier Collaboration at Johnson Controls

Johnson Controls, specifically its Wuxi Compressor team, was struggling with high imported parts inventory, frequent material shortages, and the burden of manually managing high-volume supplier confirmations. Before LeanDNA, the team relied on Excel-based PO lists and SAP re-entry, which created version-control issues, delays, and data-entry errors.

Using LeanDNA’s Supplier Workbench and Supplier Connect, Johnson Controls automated PO tracking and supplier collaboration with real-time SAP synchronization. The result was clearer visibility into supplier confirmation rates, stronger supplier adoption across three sites, improved buyer engagement, and better inventory accuracy, while helping the team reduce firefighting and focus on optimizing safety stock, delivery performance, and cycle counting.
