Paving the way for AI with data governance
Data is the lifeblood of AI, which holds potential to make government departments more efficient and improve public services.
This roundtable will look at how ready government data is for AI, and the practical steps they can take now and over the longer term to ensure they can capitalise on the benefits of AI. It will also share details on successful use cases within government, and how to measure the effectiveness and value for money in AI developments across the public sector.

Making sure government meets its priorities: how government can use data to measure performance
The data that governments around the world collects provides vital insight into the services they deliver, and for public servants it is imperative that they use the information their work generates to measure how well delivery is progressing.
In the UK for example, data will play a vital role in helping government make progress on its five national missions: to kickstart economic growth, make Britain a clean energy superpower, improve public safety, break down barriers to opportunity, and build an NHS fit for the future.
This session will look at some of the key opportunities in these areas and the cross-cutting data fundamentals required to better use data towards achieving the missions and tracking progress along the way.

Data sovereignty: why it matters and what to do about it
In the age of increasing use of cloud storage, governments around the world are increasingly grappling with the idea of data sovereignty. This refers to the idea that data – such as intellectual property, financial data, or personal information – collected or stored in a particular geographic location, such as a specific country, should be subject to the laws of that location.
Providing this security is one way that governments can boost trust in how data is used in government, but governments are concerned that they do not have full sovereignty over its data when it stores data in the cloud.
Some governments have warned that this has the potential to damage trust in government, and means that data could be subject to foreign laws and be disclosed to another government.
This session will look at how government can tackle the risks around data sovereignty, including deciding on what data can be stored in the cloud, improving data encryption, and working to balance security risks with business benefits – such as using cloud to help overhaul ageing IT infrastructure.

Building ‘tell us once systems’ for data in government
Governments around the world are focused on improving data sharing to unlock better and more efficient public services, with the objectives of improving of data quality, linking across sets, and creating single owners that can share across government.
This session will discuss how governments around the world are building better data sharing systems across government. This will include the development of integrated data systems across departments that allow service users to tell government about changes in their circumstances once, and have it updated across all of government, making life easier for citizens and enabling more responsive services. The session will also discuss how developments such as the creation of a National Data Library can help civil servants better identify the data they need.
