The upgrade2 project gave us the biggest challenge that we had faced to that moment. Not on this was a truly unique product (with nothing comparable in the market at that moment) but also had a very wide range of technical and business challenges that needed overcoming. The project architecture required a Central Reservations System (CRS) that would communicate with any only booking engine using a proprietary and innovative browser level interface. It needed speed, reliability and the ability to pick up reservation records from a truly wide range of sources (PMSs, Channel Managers, CRSs etc.) and required a very rapid pace for development. The Upgrade2 project helped us hugely with the enhancement of our ability to build interfaces for a large number of main players in the hotel industry.
