A initial Mentor proof-of-concept prototype was developed with the Royal Australian Navy, Novonics Corporation (US) and NAVSEA (Naval Sea Systems Command, Corona, US) in mid-2003 and was subsequently used successfully during the Coalition Readiness Management System (CReaMS) training event in September 2003 at HMAS Watson in Sydney.

The September 2003 CReaMS Phase III event was a joint training exercise between the Australian and US Navies that combined real and simulated forces in both countries. Mentor was the first tool that either the RAN or the USN had seen that delivered comprehensive, facilitated AAR debriefing capabilities to the entire coalition force in a timely manner.
