Challenges in using data across government
The National Audit Office (NAO) recently published a report examining how government uses data to implement its policies and reform public services. The report has found that data is not seen as a priority by government, the importance of investing in quality data is not well understood, and there is a culture of tolerating and working around poor data.
Data is crucial to how successfully government can: deliver services that work for the people who use them; improve its systems and processes; and support better decisions. The NAO has repeatedly highlighted the importance of evidence-based decision making in government, and the problems that arise when data is missing or low-quality. This report draws together the NAO’s experience of auditing government, and recent work that has identified where the quality and availability of data has been an issue.
The effectiveness of government programmes is often compromised because data is inadequate. The consequence of this is demonstrated by the Windrush situation1, where the Home Office took action without fully assessing the impact of the quality of its underlying data. Unless the quality and availability of data is high before new policies are implemented, it can be difficult for departments to assess their effectiveness or secure hoped for benefits.
Government recognises the value of using data more effectively. It plans to produce a new national data strategy in 2020, which will be led by the Department for Digital, Culture, Media and Sport (DCMS), working with Cabinet Office2. To achieve its ambitions, government will need to resolve challenges around how to use and share data safely and appropriately, and how to balance competing demands for public money in a way that allows it to invest in data. The NAO has found government has lacked leadership on developing its use of data, and DCMS has acknowledged that it needs to do more to embed its leadership role.
There are no cross-government standards on how to record data, which has led to inconsistent ways of recording information. The NAO found more than 20 different ways of identifying individuals and businesses across 10 departments and agencies, with no standard format for recording data such as name, address and date of birth. The problem is replicated for businesses and in local areas where information is recorded differently across boundaries. This makes it difficult for government to maximise its data, for example by allowing analysis across different sectors to help understand economic challenges or systematic problems.
Silo working can inhibit progress. While the Digital Economy Act 2017 has made it easier for departments to share data where it is appropriate to do so, many still lack confidence in how to share it legally. The NAO has found that civil servants are used to working within departmental boundaries, which is a hurdle to setting up and maintaining cross-departmental initiatives.
The NAO recommends that the Cabinet Office and DCMS use the 2020 data strategy to identify and address the barriers to better use of data. They should set up clearer cross-government accountability, governance and funding for data to help deliver the strategy. The datasets that are critical to government should also be identified, and it should be established how they can be improved and shared more easily.
“Government has lacked clear and sustained strategic leadership on data, and individual departments have not made enough effort to manage and improve the data they hold. This can reduce public confidence in government’s ability to collect and use people’s data effectively.
“The right processes, systems and conditions must now be put in place, otherwise the new data strategy will become yet another missed opportunity.”
Gareth Davies, the head of the NAO
Notes for Editors
- Handling of the Windrush situation, December 2018.
- DCMS has the main responsibility for data and for use and development of the Digital Economy Act 2017. In April 2018, it took responsibility for data-sharing, data ethics and data governance from the Government Digital Service (GDS), part of the Cabinet Office. GDS retained responsibility for supporting the digital, data and technology profession. The cross-government Data Advisory Board revised its Terms of Reference in January 2019 to include responsibility for the national data strategy, which includes promoting best practice and supporting development of cross-government policies and standards. It is also overseeing a cross-government project to improve data quality and accessibility, increase data use and improve public trust.

- The National Audit Office (NAO) helps Parliament hold government to account for the way it spends public money. It is independent of government and the civil service. The Comptroller and Auditor General (C&AG), Gareth Davies, is an Officer of the House of Commons and leads the NAO. The C&AG certifies the accounts of all government departments and many other public sector bodies. He has statutory authority to examine and report to Parliament on whether government is delivering value for money on behalf of the public, concluding on whether resources have been used efficiently, effectively and with economy. The NAO identifies ways that government can make better use of public money to improve people's lives. It measures this impact annually. In 2018 the NAO's work led to a positive financial impact through reduced costs, improved service delivery, or other benefits to citizens, of £539 million.
