How does NeOSS Stack Up? NeOSS enables KT to effectively manage all kinds of services including next generation converged services on one common OSS. KT was able to leverage their investments and expertise in OSS/NMS and incorporate appropriate components into NeOSS Incorporate industry standards into NeOSS design Operational functionality of most modules is comparable with many commercial COTS packages NeOSS enables KT to timely enhance their business processes according to the customer demands Real-time business process monitoring and enhancement can be achieved by separation business process from implementation Web Services approach provides NeOSS with the agility necessary to evolve and continue to deliver the management capabilities needed by a sophisticated service provider 15 APNOMS2005, Okinawa, JAPAN I.
