AI has the potential to transform public services, making them smarter, faster, and more responsive. Yet, many public sector projects remain stuck in pilot phases, never advancing to full-scale implementation. According to NAO March 2024 survey, 70% of UK government bodies reported only piloting or planning AI tools, with only 37% (32 out of 87 bodies) having any fully deployed AI use case. The reasons are often not technical. More commonly, challenges arise from governance issues, lack of trust, integration complexity, and cultural misalignment.

Proofs of concept (POCs) are efficient ways to quickly demonstrate solution capability. However, when not aligned with the broader organisational strategy, POCs can become isolated experiments with limited impact. So how can we successfully move from POCs to robust, scalable, and trustworthy production systems?

Align AI Initiatives with Business Outcomes

Structured business impact assessments are crucial to evaluate the balance between operational savings and upfront costs. These assessments help prioritise initiatives based on potential benefits and ensure that expectations across stakeholders are effectively managed. Developing a value framework is key to identify, measure, and communicate the impact of AI solutions.

Identify Cross-Department Innovation Opportunities

Conducting horizontal scans across departments helps identify shared goals and potential synergies. This systematic approach can also support collaborative development and provide insights into disruptive technologies, emerging trends, and social changes that may influence future service delivery. These scans can be followed by focused technical spikes to evaluate the feasibility and value of specific solutions. This process supports informed “build versus buy” decisions.

Future-proofed Solution Design

To support latest developments, evolving regulations, and shifting user needs, AI systems should be built with adaptability in mind. Developing model agnostic pipelines and adopting modular system design is key to update components without full rebuilds.

Robust Governance 

A comprehensive governance framework must be embedded across the AI lifecycle from data capture and model development to deployment and ongoing monitoring. Techniques such as red teaming and adversarial stress testing can help identify vulnerabilities. Addressing risks such as bias, prompt injection, hallucinations, and jailbreaks is essential for ensuring safe and ethical AI deployment. Emphasising on transparency, explainability, and accountability is vital to strengthen public trust and align with regulatory expectations.

Test, Iterate and Learn

A private beta phase involving a carefully selected group of target users allows organisations to test a minimum viable service in a controlled environment. Feedback from this stage can be used to refine features and mitigate risks before a broader public beta launch. This phased approach enhances service reliability and stakeholder confidence.

Build AI Literacy Across the Organisation 

Equipping staff with the skills to understand and responsibly use AI tools is essential for optimal utilisation and improving workflow efficiency. Internal AI literacy not only empowers teams to innovate with confidence but also strengthens governance by increasing awareness of ethical and technical limitations.

Apply Real-World Lessons to Scale Responsibly

Public sector organisations can further accelerate their AI maturity by leveraging real-world learnings from early adopters. Projects that focus on strategic partnerships, bringing together domain expertise, technical capability, and a deep understanding of public service priorities, can significantly reduce delivery risk and shorten time to impact. Drawing from our experience collaborating with local and central government bodies, we've seen how bespoke, mission-aligned AI systems can enhance public safety, improve operational resilience, and unlock actionable insights across domains, from urban planning to cybersecurity. These lessons underscore the value of sustained, evidence-led innovation when moving from pilot to production.

Scaling AI in the public sector is as much about trust, culture, and governance as it is about technology. By embedding strategic alignment, strong governance, cross-departmental collaboration, and ethical practices from the outset, public sector organisations can move beyond pilots and deliver AI solutions that are truly transformative.
