The amount of data generated worldwide is increasing at an astounding pace – by 40 % annually. It will increase 30 fold between 2010 and 2020. Big data analytics can be an immensely powerful tool to monitor how services are performed, increasing transparency and allowing for better results, processes and decisions. However, many public services are not able to fully manage and analyse the information to fully benefit from its immense potential. By creating synergies and cooperation between the Commission and Member States, leading to more effective and informed actions by public administrations, it is possible: - to identify concrete big data and open knowledge opportunities and requirements in public administrations and in specific policy contexts; - to promote cooperation among the Commission and Member States in order to accelerate the data-driven transformation.
