Government is not doing enough to promote the effective sharing of data, which is stopping departments from maximising the savings they could make from data analytics. Government bodies have legal frameworks through which to share data, such as those established by the Digital Economy Act 2017, but find it time-consuming and difficult to do in practice. The PSFA told us it is taking steps to make this process simpler and quicker. The PSFA also told us it is building a library of counter- fraud controls to encourage and enable better data sharing and to make it easier for government bodies to know what datasets and tools are already available. GDS said it was building a single data platform for use across government that will enable government bodies to find and use data assets. But government does not make full use of the other data- sharing tools available to it. For example, the National Fraud Initiative tool (NFI), which local authorities must use and through which they save millions of pounds by matching their own data with that of other local authorities, is not mandatory for central government. This means the NFI does not benefit from much of central governments data to help flag more potential fraud, and that central government itself does not realise some of the potential savings. recommendation a. The Public Sector Fraud Authority should write to the Committee within 6 months to explain its progress in developing a library of counter-fraud controls. It should also set out its steps to identify and address issues with data sharing through the Digital Economy Act, to make this process simpler and quicker. This communication should include an evaluation of how its work has enabled greater sharing of data and greater use of data analytics. 5 b. In the Treasury Minute response to this report the Department for Science, Innovation and Technology should set out further information on the single data platform. This should include the timetable for completion and be
