Public service is rarely stable. Funding shifts, demand surges, and ageing systems strain against new expectations. I have learned that if transformation is not designed to withstand uncertainty, it will not survive.
Recent times don’t get more uncertain than during the eye of the pandemic storm?
When the pandemic hit, a UK Government department with a global footprint faced a significant challenge. Lockdown measures meant citizens were unable to return home to the UK, contact centres were inundated, and case-management tools were struggling to keep up. I designed a transformation programme and, for three years, led on its implementation.
I led a 50-person transformation programme, oversaw the global rollout of a replacement appointments tool, and drafted a new crisis-case management platform. When needed, I stepped in as interim Chief Architect, recruiting my successor while delivering the highest-priority work. This saw me transition from influencing decisions to taking accountability for them and the associated long-term impact.
We stabilised the service and moved from survival to structure. When I stepped away, the architecture function was established, the contact centre replacement was in flight, a new supplier for crisis and case management was secured, and procurement for an integration platform was underway. Most importantly, the department had a clear framework to guide decisions going forward.
Where are you deploying that same calm leadership now?
My current work sits within the digital office of a UK Government department focused on a critical border capability. The brief appeared simple on paper: replace a legacy system with something highly available and resilient. However, like many large-scale transformations, it involved navigating budget pressures, ambitious timelines, and several programme resets.
The department wanted to move from large programmes to product-based delivery, with fewer handovers and clearer end-to-end ownership. I led a small team to design a product lifecycle management approach aligned to the Government Digital Service Manual. It removed unnecessary handoffs and embedded user-centred practice, helping teams make decisions based on current needs, rather than historic assumptions.
How have you looked to build capabilities within the sector and BAE Systems Digital Intelligence & Land?
Client delivery matters most, but successful transformation also depends on having the right tools, frameworks and capabilities in place. I have worked to build all three.
Previously, as head of the Business Architecture sub-discipline, I developed a Business Architecture Framework designed to address two recurring challenges. Clients often struggled to articulate what they needed, while Business Architects were not always clear on which artefacts would communicate solutions effectively.
The framework pulled together technical components, user-centred artefacts, and supporting standards, enabling teams to communicate more clearly and consistently. It has since been adopted by a government-funded scientific research body and across multiple programmes in the BAE Systems Air Sector.
Over five years, I have trained more than 200 colleagues across five courses, mostly in-person and always co-delivered. One of the most rewarding aspects of this work is seeing colleagues apply that learning on projects and bids, often returning to share their experiences or seek advice as their career develops.
Can public sector work ever truly be “stabilised”?
Public sector work is a privilege. It carries ethical as well as professional responsibilities. I act with integrity, and tell stakeholders what they need to hear, not what is easy to say. I believe there are no excuses for getting transformation wrong. The costs are too high, both financially and in terms of the time and commitment asked of client teams.
My philosophy is practical:
- Use resources responsibly
- Be honest about constraints
- Make decisions visible
- Give clear ownership to those able to carry it
- Build an operating model that bends without breaking
And the key sign of success from this philosophy is?
It’s simple. When I leave, I want the organisation to be steadier than I found it, with stronger capabilities, clearer direction and the confidence to continue succeeding long after the engagement has ended.
