MINNEAPOLIS- Carlson Hotels Worldwide has invested more than $20 million into information management systems within the past three years, which is now being leveraged to create a new wireless, portable information system. This new system provides Carlson hotel executives access to essential real-time management information. The MACH-1 (Mobile Access to Carlson Hospitality – Version 1), has made the companys management metrics portable with graphical views of key business indicators. For example, this hand-held technology provides instant access to information such as customer satisfaction trends, revenue management information, VIP guest service information, and key productivity indicators. Carlson has filed a U.S. patent for MACH-1. (10/3/00)
