Rethinking Automation: How to Scale Diagnostic Kit Production Without Adding Complexity

April 2026

For many organisations, especially in healthcare diagnostics, the assumption persists that scaling production quickly means accepting complexity, long lead times and significant capital investment. But that assumption is increasingly outdated. A recent project delivered by SP Automation & Robotics challenges this thinking, demonstrating that automation, when approached differently, can be both fast and flexible, without introducing unnecessary risk.

When Growth Outpaces Process

The trigger was a familiar one: a major commercial contract win. A global diagnostics manufacturer needed to rapidly scale production of an existing reagent kit already in the market. The product itself wasn’t the problem, the process was.

Assembly relied on manual labour, with ten operators performing repetitive, precision dependent tasks. As demand increased, so did the strain on quality, consistency and throughput. Inspection burdens grew, and rework increased. The system, while functional, had reached its natural limits. At that point, the real risk wasn’t inefficiency, it was the inability to deliver. Outsourcing production seemed to be the fallback option, leading to cost escalation, loss of control, and increased supply chain exposure.

A Different Philosophy of Automation

What set this project apart was not just the solution, but the mindset behind it. Rather than defaulting to a large, complex automation build, SP Automation focused on three guiding principles:

• Understand the process, identify problem areas and derisk areas
• Design for real-world variability, not theoretical perfection
• Build flexibility in from the start, not as an afterthought

This approach fundamentally shifted how risk was managed. Instead of pushing validation to the end of the project, the most technically sensitive elements, specifically certain assembly and manipulation operations, were tackled first through proof-of-concept work. Tooling geometry and press forces were validated early, when changes were still easy to make.

In regulated environments, this is a subtle but powerful shift: reducing validation risk not by adding layers of process, but by addressing uncertainty at its source.

Automation That Reflects the Process

The resulting system automated the entire kit assembly process without overcomplicating it. Reagent bottles are presented and placed with precision. Frame clipping is consistent and repeatable. Inspection is built into the process rather than bolted on. Rejects are handled automatically. Downstream labelling is seamlessly integrated.

What’s notable is not just what the system does, but what it avoids: unnecessary complexity. Just as importantly, the platform was designed to accommodate change. Different bottle geometries, spacer components and product variants can be introduced without redesigning the system. In a sector where SKU proliferation is common, this kind of flexibility is not a luxury; it is essential.

The Real Impact: Beyond Throughput

The headline result, a tenfold increase in productivity, is significant. So too is the reduction in labour from ten operators to one, in turn upskilling into more rewarding roles, but the deeper impact lies elsewhere. Quality issues tied to manual variability were eliminated at source. Inspection burdens dropped because the process itself became more reliable and the reliance on agency labour disappeared. Most critically, the client avoided outsourcing production, retaining control over both quality and supply. This is where well-executed automation proves its value: not just in efficiency gains, but in enabling better strategic decisions.

Designing for What Comes Next

Too often, automation systems are built to solve today’s problem and become tomorrow’s constraint. In this case, flexibility was treated as a core requirement. The same platform now supports multiple product SKUs with minimal changeover by simply adapting components such as reagent bottles or spacers. The result is a system that continues to deliver value long after initial deployment, without the need for additional dedicated machines or repeated capital investment.

Building Confidence, Not Just Capability

An often-overlooked outcome of automation projects is organisational confidence. For the client’s engineering leadership, this project demonstrated that complex automation does not have to be slow, opaque, or risky. With the right approach, it can be delivered quickly, transparently and predictably.

That confidence translated directly into further investment, with additional machines deployed for related processes and long-term support structures put in place.

A Broader Lesson for Manufacturing Leaders

For teams under pressure to scale production, the takeaway is clear. Automation is not inherently complex or high risk. It becomes so when it is overengineered, poorly sequenced, or disconnected from the realities of the process it is meant to improve. The alternative is not simplification for its own sake, but focused engineering, targeting the true constraints, validating early and designing with change in mind. When done well, automation stops being a bottleneck and becomes what it should be, a commercial enabler.
