Blog 6/12
For many machine builders and OEMs, keeping manufacturing and assembly in-house feels like the safest route. But beneath the surface of familiarity lies a growing burden – one that quietly limits capacity, slows innovation, and drains critical resources.
In this new campaign series, The Hidden Cost of In-House, we uncover the operational pain points that often go unspoken but have a lasting impact on business performance. From skills shortages and missed delivery windows to bottlenecks in engineering and rising quality issues, each article reveals a hidden cost and shows how strategic outsourcing can eliminate it.
This 12-part quickfire blog series challenges conventional thinking. It invites OEM leaders to step back and re-evaluate what “in-house” is really costing them – not just in terms of money, but in missed opportunity, agility, and growth.
Because outsourcing has nothing to do with losing control. It’s about regaining focus. It’s about building smarter, scaling faster, and staying competitive, no matter what challenge is chucked in for good measure.
For many machine builders and OEMs, a growing order book should be a cause for celebration. It signals strong demand, market confidence, and commercial momentum. But too often, it brings the opposite feeling – pressure, panic, and the looming risk of letting customers down. When in-house teams can’t keep pace, that healthy backlog starts to feel like a liability.
What begins as a manageable queue of projects quickly becomes a mounting list of overdue builds, missed delivery dates, and frustrated stakeholders. What ensues is a mad scramble to reprioritise, longer working hours and corner cutting just to stay afloat. But the more they push, the less effective the output becomes. Lead times extend, quality dips, and communication breaks down. The backlog doesn’t get smaller; it just gets harder to manage.
The temptation is to ride it out. Delay new orders. Ask customers to be patient. Reallocate resources from other parts of the business. But that kind of patchwork response rarely works. It might keep things moving for a short while, but it doesn’t fix the core issue: the business has outgrown its in-house capacity.
And that’s not a failure – it’s a signal. One that the business has reached a critical point of inflection. Either you scale your capability, or you scale back your ambition.
Strategic outsourcing offers a clear path forward. By partnering with a manufacturing specialist, OEMs can offload specific build stages, sub-assemblies, or even full machine build production to create immediate breathing space. This isn’t about losing control. It’s about regaining it, through structure, clarity, and dependable external support.
With the right partner, throughput increases without compromising quality. Internal teams can refocus on engineering, customer engagement, and new product development instead of being stuck on repeat production cycles. Delivery dates become realistic. Workload becomes manageable. And backlog turns back into real opportunity.
The key is not to wait until the queue becomes a crisis. Outsourcing works best when it’s proactive, not reactive. When OEMs use it to maintain momentum, not just recover from delays. That shift in mindset transforms outsourcing from a short-term fix into a long-term growth strategy.
A full order book should drive the business forward, not drag it down. If clearing the queue means sacrificing quality, burning out teams, or turning away new business, the model is no longer sustainable. It’s time to rethink the build – not just how much you’re doing, but where and with whom.

Hidden Cost of In-House 12/12: In machine building, success depends on where you direct your time, energy, and expertise. Yet for many OEMs, the focus has shifted away from where it creates the most value.
Hidden Cost of In-House 11/12: For many machine builders and OEMs, keeping production in-house feels like the most cost-effective way to operate. But when you dig deeper, the numbers often tell a different story.
Hidden Cost of In-House 10/12: For many machine builders and OEMs, innovation starts strong. But then comes the challenge: moving from concept to production.
Hidden Cost of In-House 9/12: In modern machine building, supply chains have become increasingly fragmented. And for many OEMs, managing these relationships has turned into an operational burden.
Hidden Cost of In-House 8/12: For many machine builders and OEMs, the opportunities have never been greater. Yet whilst the possibilities grow, many manufacturers are constrained by what’s happening much closer to home.
Hidden Cost of In-House 7/12: Machine builders are under constant pressure to innovate. Customers want smarter, faster, more integrated systems. But as products evolve, production demands do too.
Hidden Cost of In-House 6/12: For many machine builders and OEMs, a growing order book should be a cause for celebration. But too often, it brings the opposite feeling – pressure, panic, and the looming risk of letting customers down.
Hidden Cost of In-House 5/12: Every machine builder knows that quality is a reputation-maker or breaker. But as production complexity grows and internal pressures rise, many OEMs find themselves slipping into a reactive mode. Quality control becomes damage control.
Hidden Cost of In-House 4/12: Technical skill is the lifeblood of any machine builder. But across the sector, that capability is under threat.
Hidden Cost of In-House 3/12: For many OEMs, firefighting has become business as usual. But it’s also a major reason why forward planning never quite gets off the ground.
Ian Knight, Chief Information Officer at PP Control & Automation (PP C&A) challenges the prevailing, often vague narrative around AI adoption and reframes the conversation around a more practical starting point: operational constraints.
Artificial intelligence is no longer a distant concept for manufacturers. It is already being explored across quotation, production planning, engineering, quality, supply chain and customer service functions. Yet, for many organisations, the gap between experimentation and meaningful operational impact remains difficult to close.
A leading aquaculture specialist – that is changing the way fish are vaccinated safely – has signed a major manufacturing deal.
On paper, defined discipline-specific suppliers can look organised. However, every additional supplier introduces another handoff, and every handoff creates another point where time, quality, communication and accountability can be lost.
Very rarely does growth not surface because an OEM lacks ambition. Shortcomings arise because operating models built to support such ambition don’t evolve quickly enough.
Recent weeks have brought two important industry moments into sharp focus, concluding that demand for AI and automation is rising, but investment, skills, and long-term thinking must follow.
For decades, one question has sat at the heart of operational strategy for machine builders and OEMs: make or buy? It’s a familiar debate and it isn’t the wrong question by any means, but perhaps it is an incomplete one.
In most machine building businesses, change is still treated as an exception. A late-stage drawing revision, component substitution, or wiring tweak discovered during build. Each one is handled, resolved, and signed off. And then everyone moves on. But what if that’s the wrong way to think about it? What if change isn’t the disruption to the system but the system itself?
