Information on the faults is gathered and passed to specialist teams (2nd line core, third party vendors, transmission teams etc) for support. This included performance issues in voice core, packet core, DAB, IMS.- Working closely with the customer experience response team to identify areas of the country with network issues and major outages which we aim to help resolve in the shortest time possible.- Building custom KPIs and alarms/alerts using PrOptima formula language. This enabled us to keep up with and react to any alerts on a variety of network elements across the estate, bringing down the time to react.- Building custom performance monitoring reports to enable monitoring and analysis of both core and radio elements within PrOptima. These are used for daily activities and have continuously improved to allow enhanced monitoring.- Customer engagement whilst working with Nokia for development of a ‘CSOC tool’ (Customer Service Operations Centre) Scoping out key requirements and giving input on which KPIs should be prioritised for alignment with service level monitoring.- Vendor management with multiple suppliers such as Nokia, Ericsson, Connect 44, NTT data etc. Providing input from O2s perspective on things such as software and hardware faults.
