Most UK manufacturers already own the capacity to grow significantly. They just can't see it yet. This National Productivity Week, one Greater Manchester business leader's story reveals what happens when those changes and what it could mean for yours.

The average UK factory is operating under its true capability, day in, day out. That's not a market problem or a demand problem. That's hidden capacity sitting idle on the shop floor, in equipment businesses have already paid for.

For many small and medium-sized manufacturers in Greater Manchester, the gap between current output and what's genuinely achievable isn't a mystery. It's a measurement problem that one local business proved this is entirely solvable.

The real cost of "The way we've always done it"

Manual processes don't just slow production down. They hide the true scale of what's being lost. When teams record downtime by hand, log output at the end of a shift, or rely on gut feel to identify bottlenecks, the numbers they see are almost always better than reality. Errors go unrecorded. Delays get normalised. And the cumulative cost – in lost output, missed capacity, and wasted labour – never makes it onto a board report.

This isn't a criticism of hardworking teams. It's a structural problem with manual data collection in high-volume environments. The moment manufacturers start measuring properly, the response is almost always the same: surprise at how large the gap actually is.

For growing SMEs taking on new work or entering new markets, the stakes are even higher. Winning a contract you can't fulfil reliably – because your process isn't yet built for scale – is a reputational risk as much as an operational one.

Digimock: How a packaging producer scaled a business without adding headcount

When Digimock, a Greater Manchester flexible packaging producer, decided to expand into co-packing services, they faced an immediate challenge: their existing date-coding process was entirely manual. Every pack was labelled by hand – time-consuming, error-prone, and fundamentally unable to support the volume their new business line required.

Through GM Business Growth Hub's manufacturing service, Digimock was connected with the North of England Robotics Innovation Centre (NERIC) to assess where automation could make the biggest difference. The solution was implemented without disrupting their core production, and the results were immediate. By adopting the new semi-automated date-coding system, the company has been able to increase its capacity from 2,000 packs per day to 1,800 packs per hour.

That's not a marginal efficiency gain. That's a transformation in what the business can offer its clients – and a platform for sustainable growth in a new market. Critically, it also eliminated the error rates that had made manual labelling a quality risk, improving both consistency and customer confidence.

Digimock's experience reflects a pattern the GM Business Growth Hub manufacturing team sees repeatedly: the businesses that grow fastest aren't always those that invest the most. They're the ones that measure the right things, identify the right intervention, and move decisively.

3 questions every manufacturing leader should ask

National Productivity Week is a useful prompt to step back from daily operations and examine the fundamentals. For manufacturing business leaders, that means asking three questions that are simple to pose but rarely examined honestly:

• Where are the real bottlenecks? Not the ones everyone talks about – the ones that don't make it into the weekly report because they've become background noise.
• Which manual processes could be automated – and what would the payback period actually be? Return on investment for automation is often faster than businesses expect, particularly when labour cost increases are factored in.
• Are we measuring output accurately enough to know what we're leaving behind? If the answer is "probably not", that's the place to start.

These aren't questions that require a large capital programme to answer. In many cases, a structured conversation with an experienced manufacturing advisor can surface the answers within hours – and point toward practical next steps that deliver results within months, not years.

AI, robotics and automation: The opportunity and the reality

There is significant noise around AI and advanced automation in manufacturing – much of it focused on large-scale transformation programmes that feel out of reach for most SMEs. The reality on the ground is more practical and more accessible than the headlines suggest.

For most manufacturers in Greater Manchester, the most impactful near-term opportunity isn't a full AI deployment. It's identifying one or two high-volume, repetitive manual processes – like Digimock's date coding – where a targeted semi-automated or cobot solution can unlock meaningful capacity at a manageable investment and a clear ROI.

That said, the direction of travel is clear. Manufacturers who begin building their automation capability now, even incrementally, are better positioned to take the next step when the opportunity arises.

The key is not to treat technology adoption as an all-or-nothing decision, and not to make it alone. The combination of expert manufacturing advice, access to the right partners, and fully funded business support means that the barriers to getting started are lower than most manufacturers realise.

You don't have to figure this out alone

Productivity improvement is a continuous journey, there is no single destination, and no manufacturer has fully "solved" it. What separates the businesses that make consistent progress from those that don't is rarely ambition or intelligence. It's access to the right expertise at the right time, and the structures to act on what they find.

GM Business Growth Hub's specialist manufacturing team works with businesses across Greater Manchester to do exactly that: identify where productivity is being lost, connect manufacturers with the right technical partners and innovation centres, and support implementation every step of the way.
