O2 Germany

Harald Grüssinger, Service Performance Management, O2 Germany
As it grew, O2 Germany recognized that it needed a way to guarantee outstanding Quality of Service (QoS) -- whether it was delivering day-to-day services or handling communications for massive special events. O2 determined that Telcordia® Service Director was the only commercially available product that could perform simultaneous, near-real-time analysis of all the network and system parameters that affect voice and data quality.
