As we close out December 2025, the pace of technological change feels less like a curve and more like a vertical line. The release of Claude Opus 4.5 this month—outperforming human engineering candidates in internal benchmarks—is not just another headline. It is a signal.

For those of us in the public sector, it signals that the era of "experimentation" is ending, and the era of strategic integration has begun.

As a Business Relationship Manager (BRM), my role sits at the intersection of technology and organisational purpose. I see first-hand that we are moving away from asking, "What can this chatbot write for me?" to a far more profound question: "What value can this agent deliver for the citizen?"

Here is why the shift to Agentic AI and Explainable AI represents the greatest opportunity for public service transformation in a generation—and why we must be ready.

From Passive Assistants to Active Agents

The most significant shift we are witnessing is the rise of Agentic AI. Until recently, Generative AI has been a passive assistant—it waits for a prompt, gives an answer, and stops.

Agentic AI changes the paradigm. These are autonomous software systems capable of reasoning, making decisions, and executing multi-step tasks with minimal oversight. Imagine an AI agent that doesn’t just draft a response to a citizen’s query about a complex benefit claim, but actively collaborates with other agents to check eligibility criteria, verify data against policy guidance, and propose a final decision for a human caseworker to sign off.

For the public sector, where "doing more with less" is a perennial challenge, this offers a pathway to radical efficiency. It frees our brilliant civil servants from administrative drudgery, allowing them to focus on what humans do best: empathy, judgment, and complex problem-solving.

The ‘Black Box’ Problem: Why Trust is our Currency

However, with great capability comes a critical responsibility. In the private sector, if an AI recommends the wrong movie, it is an annoyance. In the public sector, if an AI miscalculates a tax code or a grant application, it affects a livelihood.

This is why the concurrent rise of Explainable AI (XAI) is arguably more important for us than the raw power of the models themselves. We cannot govern through a "black box."

As we integrate these tools, we must demand transparency. We need systems that show their working—providing a clear audit trail of how a decision was reached. This isn't just about technical debugging; it is about maintaining the public trust. As stewards of public services, we must ensure that every automated process is fair, accountable, and transparent by design.

Building a Skilled Government

Technology, however, is only 10% of the transformation. The other 90% is people.

A recent insight from Google Public Policy, Building Skilled Governments, highlights a crucial truth: unlocking AI’s promise requires a workforce that is not just "tech-literate," but "AI-ready."

This does not mean every policy advisor needs to become a prompt engineer or a data scientist. It means cultivating a culture of curiosity. It means upskilling our teams to understand value streams—to spot the bottlenecks in their own work where an AI agent could assist.

Events like our recent organisational Innovation Day proved that the appetite is there. When we connect frontline staff directly with the tools of the future, they don't see a threat; they see a solution to the frustrations that hold them back from serving the public effectively.

The BRM as the Connector

This is where the Business Relationship Management discipline becomes vital. In 2026, the BRM is no longer just the bridge between "IT" and "The Business." We are the Value Engineers.

It is our job to look at a tool like Claude Opus 4.5 or a hybrid quantum-classical model and translate it into a tangible public benefit. We must be the ones to ask: Does this solve a real problem? Is it safe? Does it align with our values?

The future of the public sector isn't about replacing people with machines. It's about empowering our people with the most advanced tools history has ever produced.

The technology is ready. The question for 2026 is: Are we?
