Question to the Cabinet Office:

To ask His Majesty's Government, following the wrongful convictions that occurred as a result of faulty Post Office Horizon software, what plans they have to integrate advanced oversight technologies that ensure accuracy and reliability of software used in public service systems to prevent any future issues.

This was one of the greatest miscarriages of justice in our nation’s history, which is why we set up an independent inquiry to establish culpability and are bringing forward legislation to make sure those convicted as a result of the Horizon scandal are swiftly exonerated and compensated.

It is right that we do not pre-empt the conclusions of the ongoing, formal inquiry, but once the full facts are established we will consider all options.

The Central Digital and Data Office (CDDO), in the Cabinet Office, established in April 2021 to lead the Government’s Digital and Data Function, is the strategic centre for digital transformation which includes measuring services against digital and technical standards.

CDDO is defining best practice patterns and practices for software delivery to ensure high quality software delivery via the automation and regular testing of software quality throughout development. Use of ‘oversight technologies’ such as automated testing would follow user technology good practice, user needs and the risk profile of the system.

In addition to the software testing, a core requirement of the development process, the Service Assessment Model assesses newly created services, checking for evidence that departments are regularly monitoring and mitigating quality and reliability issues.
