Exploiting small and big data for machine learning based incident prevention

Device failures are unavoidable where large numbers of different equipments are in operation to serve customer needs. This is true to British Telecommunication, too, that provides landline internet services to thousands of enterprise customers all around the globe. It is in everyone’s interest to react and repair any problems as fast as possible. Or even better, anticipate the future problems and prepare for them.

The presentation is focusing on two approaches experimented at BT Business that give analytical support to the incident management teams.
The first approach predicts the number of expected incidents for the coming weeks so that resolution teams can plan their rostering accordingly. Lacking any further information, except the past incident numbers, the problem could be treated as a time series forecasting task, with some hitches. One hardship was the very high volatility of the daily incident numbers, besides others. A set practical challenges will be touched besides outlining the scientific approach.

The second approach is processing large amount of sensor data in a near-real-time fashion and trying to spot indicators of an upcoming failure on the device level. As at the time of writing this synopsys the project is still in an experimenting phase, more focus can be promised to put on the immediate challenges with the sheer management of the immense volumes of the source data and how the toolset of Google Cloud can support it. Those interested in the analytical aspects can be given some guidance as well on how popular textbook methods fared with the problem when used just naively.
