Joanna Davinson at the Home Office (2017–2021)

The Home Office is one of the most complex departments in government. It manages immigration and visas, passport systems, border operations, law enforcement, public safety technologies and national security data.

Joanna’s role was to lead this environment, strengthen its foundations and support long-term improvements.
What She Was Responsible For
Managing Major Technology Systems
She oversaw many of the core systems used for immigration, borders, policing and internal operations. Some of these systems are decades old, and modernising them requires careful planning. Her work focused on improving stability, reducing outages and ensuring essential services remained reliable.
Improving Data Use and Governance
Because the Home Office manages highly sensitive information, secure and responsible data management is crucial. Joanna helped improve data standards, reduce duplication and strengthen the way data is shared and protected across departments.
Leading Digital Transformation Work
She supported the development of modern digital services that were more efficient and easier to use. Transformation at this scale often takes years, and her work helped lay the groundwork for current improvement programmes.
