This document summarizes a conference on big data in the telecommunications industry. A key theme was that while telcos collect vast amounts of customer data, they have failed to fully utilize this data due to organizational silos. Belgacom provided a case study on how they consolidated customer data sources to better use all available information. Additionally, presenters discussed challenges around data quality and skills gaps that limit telcos' ability to generate insights from their data. Successful case studies demonstrated using predictive analytics to improve network investment and customer experience management. Overall, the conference highlighted that telcos should focus on using big data internally before attempting external sales of customer insights.
