New Case Study! Just-in-time Co-development of Business Process and Softwareby Tony Canty, CIO, Labatt Food Services

In its first 3 years of use, the system has reduced inventory investment by over $8 million dollars while reducing out-of-stock items on orders by 50%, despite a 15% increase in sales.
