The Government Data Quality Framework sets out the principles for building a data quality culture across government, but how will this work in practice across so many large organisations and so many data sources? The Government Data Quality Hub (DQHub) at the Office for National Statistics has recently been established to address these challenges, through setting direction and build data quality capability across government. James Tucker, Head of the DQHub, will take us through the ambitions for data quality in government, and the need to work across organisations in government and wider to achieve them.
