Martin Florian (KPMG) will focus on how the state could improve the quality of its data so that we can trust them. Consequently the discussion will focus on the systematic measurement of data quality and benchmarking of information systems in public administration, introducing new methodology and basic indicators. Marek Šurek (xIT) will look at the possibility of interconnecting data with each other, which would allow the creation of a central data model. At the end of the discussion, Tomáš Kysela (ÚPVII) will think about how to improve data quality in practice.
