'A practical guide to transforming the business of Government' from the TechAmerica Foundation's Federal Big Data Commission. While geared towards the specific context of the United States, the findings, discussions and examples given in this paper have much more general relevance. It is not exclusively about the production of official statistics but about uses of Big Data across governments.
