Smart Factories: From Vision to Reality—Why Most UK Businesses Still Miss the Mark

In early 2019, the UK inaugurated its first smart factory, leveraging the nascent 5G network to achieve lightning‑fast data transfer. While a milestone, it paints a narrow picture of the industry’s progress. George Walker, managing director of industrial automation provider Novotek UK and Ireland, argues that the majority of UK manufacturers remain priced out of the Industry 4.0 wave.

Industry 4.0 promises an era of intelligent, networked devices, seamless automation, and digital tools that together boost productivity and efficiency. In theory, machines will talk to one another, monitoring performance and adjusting processes in real time, freeing human workers for supervisory and product‑management roles.

The reality, however, shows that the revolution has yet to manifest at scale. We have the technology, we stand on the threshold, but implementation is uneven. The lesson from the Second Industrial Revolution—when electrification truly transformed factories—reminds us that the catalyst is the adoption of the underlying infrastructure, not just the shiny new ideas.

In the fourth industrial revolution, data is the new electricity. For a true transformation, firms must first capture, store, and analyse their operational data. Unfortunately, many businesses are sidelined by the prevailing historian software model, which charges per data tag regardless of whether the data is used.

Historian software is essential for Industry 4.0, acting as a robust platform that aggregates streams from SCADA systems, sensor outputs, and equipment telemetry. Each data stream is stored as a tag, awaiting analysis. Until examined, these tags are merely numbers; once processed, they become actionable insights.

The current pricing model forces companies to purchase a set number of tags—often far exceeding what they actually need—leading to significant overheads. Medium‑to‑large enterprises may pay for 10,000 tags when only 400 are utilized, while smaller firms find the costs prohibitive.

This pay‑for‑tags approach stifles innovation. Novotek’s partnership with GE Digital addresses this gap by introducing the GE Digital Historian, a subscription‑based platform that charges based on the value derived from data, not on unused tags.

With the GE Digital Historian, the first 200 tags are available for free, allowing firms to analyze, visualise, and generate reports without upfront cost. Beyond that, each additional tag incurs a nominal fee, making the solution scalable—from small workshops to multinational operations—and far more cost‑effective than traditional competitors.

Smart factories hold undeniable promise, but without affordable, scalable data capture and analysis, they remain a pipe dream. By rethinking how historian software is priced and delivered, we can finally turn Industry 4.0 from an aspiration into a tangible reality.
