Case Study: Western Digital achieves 95%+ on-time delivery and 10%+ safety-stock improvements with Blue Yonder Luminate Planning

Creating a Flexible Supply Chain at Western Digital

Western Digital, a global leader in flash memory storage (formerly SanDisk), faced a resource-intensive, spreadsheet-based planning process that limited visibility and flexibility across OEM and retail channels. The company needed a daily, integrated supply chain plan with end-to-end demand and supply visibility, better inventory positioning through customer segmentation, and a multi-layered postponement strategy to reduce stock while improving service.

Western Digital implemented Blue Yonder’s Luminate Planning to automate forecasting, optimize inventory and silicon allocation, and enable frequent re‑planning and what‑if analysis. The solution improved safety stock and on‑time delivery metrics by more than 10%, delivered over 95% performance to promised dates, boosted inventory turns, and shortened the frozen production window from weeks to days.
