11 oktober 2022

During this Vision Dinner, Olaf Slomp, Head of Data Quality at KPN and Geert van der Hoek, Director of Data, Innovation & Analytics at NS, will guide you through their data strategies. For example, KPN uses a data mesh structure. The NS, on the other hand, uses a combination of data structures. After the presentation there is an open discussion with Olaf, Geert and the other participants. You are most welcome to participate in this discussion!

  • Small scaled peer session
  • Open dialogue by means of the Chatham House Rule

It is common for organisations to go to great lengths to centralise all collected data so that they can simplify processes. After all, centralised data creates a single source of truth, enabling them, for example, to improve the customer experience. Yet today we also see an opposite movement. The need to leverage richer data sets with greater volumes and speed has fueled a new wave of innovation in data architecture and has fueled the emergence of modern data platforms such as data mesh.
