This document summarizes discussions from Sessions 1 and 2 of the BYTE Workshop on Work Package 5: Foresight Analysis. Session 1 reviewed previous case study findings on how big data impacts various sectors and identified open questions around its legal, political, technological, and business model implications. Session 2 focused on identifying objectives and structuring problems regarding big data in the EU. Participants were divided into groups representing SMEs, large companies, policy, and consumers to brainstorm measures, objectives, and problem definitions in these areas. The results from the group work in Session 2 were then presented to the full workshop.
