In 2018, the two premier London-based events, CDO Europe and CAO Europe, are merging into one mega-event – Chief Data & Analytics Officer, UK 2018. CDO Europe 2017 was a symposium of kindred spirits, with a good spread of industries represented and abundance of experienced practitioners. The agenda has been impeccably researched organised and managed by the Corinium team, and I have particularly enjoyed the discussion group format, which, in my opinion, produced some fascinating insights in how many ways the data challenge is tackled.
