By Deborah Austin An upgrade of RiverOne Inc.'s INTERactive supply-chain software suite adds features to help electronics-manufacturing participants share critical business information across multitier outsourcing relationships. Version 4.5 of INTERactive enables trading partners to visualize and respond to exception events in real time, achieving alignment and executing build-to-order and automated-replenishment programs. It also gives VMI (vendor-managed inventory) suppliers access to the most current inventory and forecast data. Enhancements include global track-and-trace, which allows customers to locate inventory in transit, and an expanded business-rules library. Supply-chain software solutions provider RiverOne, headquartered in Westlake Village, Calif., was formed in November 2001 by the merger of Need2Buy and Efinity. Its INTERactive solutions -- designed to work with existing enterprise resource planning and supply-chain-management software -- aim to help improve "outside the four walls" communications across extended electronics-manufacturing supply chains.
