As part of our series of conversations between high-profile government figures, Cat Little – who today takes over at the helm of the Cabinet Office – discusses leadership, AI and how to deliver better services with Megan Lee Devlin
Cat Little joined HM Treasury in 2020 as director general, public spending. Having arrived at the finance department right at the beginning of the Covid crisis, just a few months into her new role Little found herself running a government spending review from home, typically with “a couple of dogs with me, causing chaos in the background”.
Despite such distractions, the public spending chief found “lots of positives” in conducting the process virtually. The experiences of 2020 and 2021 – which brought a full, three-year comprehensive spending review – “turbo-charged” the Treasury’s use of digital tools, according to Little.
She took on the position of acting permanent secretary in September 2022 and the following month was appointed to the post of second perm sec. In this role, she has overseen public spending, as well as international and national security policy, alongside her positions as head of the government finance function and chair of the Finance Leadership Group for Government.
Today, Little takes up a new role as civil service chief operating officer and permanent secretary of the Cabinet Office, taking over from Alex Chisholm.
Her departure comes as the Treasury prepares to publish a long-term Future of Finance strategy next year. As part of the review, according to Little, the department will continue to seek “innovative ways to deliver more and better outcomes through tech, data, AI and better use of our talented people’s time and energy”.
CSW's sister title PublicTechnology has been working with the Cabinet Office’s Central Digital and Data Office on our ongoing Digital Leaders’ Download series of interviews, featuring discussions between CDDO leadership and some of government’s most high-profile figures – in the fields of digital, data, technology and beyond.
The most recent interview saw Little talk to recently departed CDDO executive director Megan Lee Devlin, shortly before her own move.
Megan Lee Devlin: Cat, while you are an accountant, senior civil servant and board member, you are also a very active supporter of the digital agenda. What does being a digital leader mean to you?
Cat Little: We are all digital leaders in government and we have a number of responsibilities, most importantly around culture and behaviours. Digital is a fundamental part of the way we do business in our day-to-day jobs. It’s our responsibility to look after policy, money, operational delivery, and digital is part of that. We don’t all need to be experts in digital but we do need to understand the expertise involved and know enough to role model putting digital at the heart of how we do our jobs.
"We are all digital leaders in government. Digital is a fundamental part of the way we do business in our day-to-day jobs"
MLD: Absolutely – digital has become everyone’s business, irrespective of function or profession. I’m often asked how leaders can, in practice, role model digital leadership. How do you think about that? For instance, how do you hear and learn about new developments in technology?
CL: One of the great privileges of my job is that I get involved in every single bit of the economy and the public sector. I get to talk to organisations that are delivering innovation every day – that might be private companies, public sector bodies, international government – and I get to talk to leaders who really understand our problems.
I also read a lot in this space, there are great blogs and articles published all the time – exercising that normal civil service curiosity, and using our network and relationships to think differently about the challenges we face. So many people are using digital in different ways.
MLD: And we certainly face some of the most intractable challenges here in government. What excites you most about the role of digital and data in addressing some of those?
CL: We in the Treasury are grappling with big macroeconomic challenges for the economy as a whole and one of my passions is: how do we go about delivering better services for the public sector overall? How can we be more productive? How can we be more effective? Digital thinking can be a win-win for everyone.
As we think about policy reform in the medium term for the next spending review, one of our core questions is: how can we use data and digital for better service outcomes, what are the outputs we need to produce and can we do that with less resource? There are lots of ways for digital, data and technology to drive better outcomes for less resource input; that has to be a fundamental part of what we are doing.
The thing that I am most passionate about is the fact that we can radically shift the service outcomes we are seeking to achieve by using policy alongside digital and data transformation – to be more productive and efficient by default. The public sector is so huge. If you take a great innovation in, say, one hospital in the NHS, how do you scale that effectively to all 250 hospitals across England and Wales? We need to be able to scale opportunities as the best ideas happen locally.
MLD: The world is very excited about AI at the moment, and we know there are many other exciting developments on the horizon, such as quantum computing. What’s your favourite emerging technology?
"One of my passions is: how do we go about delivering better services for the public sector overall? How can we be more productive? How can we be more effective?"
CL: I’m particularly interested at the moment in how we analyse large amounts of complex data for consistent decision making, including generative AI, complex data analysis models and large language models. These help us to give the right tools to decision makers, case workers and operational delivery teams on the ground.
MLD: Absolutely, and I know that Treasury has been thinking a lot about how AI can support its own productivity and public sector productivity. What has your department achieved through digital and data that you are especially proud of?
CL: The Treasury is really proud of the progress we’ve made so far, particularly as we are not a big operational team – we are more policy-driven – and it has taken a bit longer to accelerate in this area. One thing we did recently was run our first data hackathon, where 10 departments came together to look at generative AI to support our work on correspondence management. We are now looking at how we apply the solutions further across government collaboration – correspondence is a huge challenge for us and we are going to keep running these hackathons.
MLD: If we were to fast forward to 2025, what do you look forward to seeing in the digital and data space?
CL: There is so much going on at the moment to look forward to: improving our top 75 government services, improving the quality of data to make better decisions, as well as our promises on One Login and cross-cutting system reform. This is in addition to a strong civil service that has a strong digital and data skill set.
As I’ve already mentioned, it would also be great to see further integration of digital and data into policymaking – all these things are underway as part of the Digital Transformation Roadmap.
