Industry estimates on this vary, but they all point the same direction: the majority of AI proofs of concept built inside large organisations never make it into production. Not because the technology failed, in most cases, but because nobody had thought through what happens after the demo goes well. Ask around most UK IT departments and you’ll find at least one graveyard of promising pilots that quietly stopped being mentioned in steering committee updates somewhere around month six.
It’s a strange kind of failure, because on paper everything worked. The model performed. The stakeholders were impressed. Somewhere between that meeting and an actual production deployment, though, the project quietly stalled, and eighteen months later a slightly different team is building a slightly different proof of concept to solve a slightly different version of the same problem.
The Proof of Concept Was Never the Hard Part
Building something that works in a controlled environment, with clean sample data and no real users, is genuinely the easy part of an AI project. It’s also the part most vendors and consultancies are best set up to deliver quickly, because it’s impressive, it’s fast, and it photographs well for a case study.
Production is a different exercise entirely. It means the model needs to keep working when the data feeding it is messier than the sample set. It means someone needs to own what happens when the model gets something wrong, and how that failure is caught before it reaches a customer. It means security and compliance teams need to sign off on something that, in a regulated UK industry, may need to explain its own decisions after the fact.

Where the Handoff Usually Breaks
In most failed transitions, the break happens at a predictable point: the team that built the proof of concept isn’t the team responsible for running it in production, and the two were never properly connected. The data science team moves on to the next exciting use case. The platform and security teams inherit something they didn’t design, can’t fully explain, and are reasonably reluctant to put their name to. Nobody involved did anything wrong exactly; the process simply wasn’t built to survive a handover.
This is why organisations that consistently get AI into production tend to treat strategy, foundations, delivery and operations as a single connected process rather than four separate projects handed between teams. Deciding which use case is worth building is treated as inseparable from deciding how it will be secured, governed, and supported once it’s live — not a question to be answered after the fact.
What a Repeatable Process Looks Like
Some UK consultancies have started describing this as building an “AI factory” rather than running a series of one-off AI projects — the idea being that the path from identifying a use case to running it reliably in production should be a repeatable production line, not a bespoke exercise every time. Transparity’s explanation of how its own AI Factory approach is structured is a useful example of what that looks like in practice: strategy and discovery, secure data and AI foundations, sprint-based delivery, and ongoing operation and optimisation, treated as stages of one continuous process rather than four disconnected engagements.
Whether or not an organisation adopts that exact structure, the underlying principle holds up well across most successful deployments. A use case earns its place on the roadmap based on business value and delivery effort, not novelty. The foundational data and governance work happens before the flashy build, not after. And someone is named as accountable for what happens once the model is live. Not just for building it, but for watching it, maintaining it, and knowing when to switch it off.
Getting Past the Demo
None of this makes AI projects move faster in the short term. If anything, it front-loads work that a rushed proof of concept skips entirely. But it’s the difference between a demo that impresses a steering committee once and a capability that’s still quietly doing useful work eighteen months later, when the team that built it has moved on to something else and nobody’s left to explain how it was supposed to work.
The organisations that keep repeating this cycle rarely lack ambition or budget. What they lack is a process that survives the handover from the people who build a use case to the people who have to live with it. Fixing that is less exciting than the next proof of concept, but it’s usually the actual bottleneck standing between an organisation and AI that sticks.
