Abstract

A work-in-progress (WIP) tracking system is used to coordinate a semiconductor supply chain. The WIP tracking receives WIP updates from semiconductor supply chain vendors and generates advanced notices based on an analysis of the WIP updates and predetermined rules. The advanced notices are delivered to downstream vendors to reduce semiconductor manufacturing cycle time and unpredictability between different semiconductor manufacturing phases.
