Fault diagnosis stays human as agents read plant data

Agents can read plant data at scale and flag anomalies fast, but the judgement call on what's actually wrong, and what to do next, stays with skilled engineers who understand the machine, the process and the people around it.

What's the state of manufacturing hiring right now?

Tight. The skills gap is the single biggest thing holding manufacturers back from doing more with data. Over 50% of manufacturers cite skills shortages as the main barrier to AI adoption, and only 2% say AI is widely embedded across their operations The Manufacturer / Make UK – AI, Skills and the Future of UK Manufacturing. So the tools to read plant data exist, but the people who can act on what those tools surface are in short supply.

The scale of the opportunity makes the gap sharper. The UK ranks just 24th in global robotics density, and targeted innovation and digital investment could add £150 billion to the UK's GDP by 2035 Making it Smarter: Global Lessons for Accelerating Automation and Digital Adoption in UK Manufacturing - Make UK. That ceiling only lifts if there are enough skilled people to install, run and interpret the systems underneath it.

Which roles and skills matter most as plant data grows?

The roles that read data and the roles that diagnose faults are converging. Six in ten (59%) manufacturers cited automation and half (50%) cited wider digitalisation as trends changing jobs and skills needs, and 74% expect demand for cognitive and meta-cognitive skills to increase by 2030 Make UK – 2030 Skills: Closing the Gap. In plain terms, employers want people who can think, reason and solve problems, not just operate a line.

That's why fault diagnosis stays human. An agent can flag a vibration pattern or a temperature drift. A skilled engineer decides whether it's a bearing, a sensor fault or a process change, and what it means for safety and output. That combination of pattern reading and practical judgement is exactly the cognitive skill set employers are now chasing.

Many firms are responding by growing their own talent. 40% of manufacturers are looking to upskill their existing workforce, specifically for redeployment as a result of automation and digitalisation, and that figure increases for firms with more than 1,000 employees Make UK Executive Survey 2026. Redeployment matters because the engineer who already knows the plant is often the best person to interpret its data.

How do you hire well for data-rich manufacturing?

Start with the problem, not the job title. Decide what you need a person to judge that a system can't, then write the role around that judgement. The UK used only 101 industrial robots per 10,000 workers in 2020, so most plants are still early in their automation journey Smart Machines Strategy 2035 - GOV.UK. You're hiring people who can grow with the technology, not just match today's kit.

  • Hire for reasoning and problem solving, since 74% of manufacturers expect demand for cognitive skills to rise by 2030 Make UK – 2030 Skills: Closing the Gap.
  • Blend buy and build: recruit externally for scarce data skills, and upskill the engineers who already understand your plant.
  • Test diagnosis in the interview. Give a real fault scenario and ask how the person would read the data and decide.
  • Move quickly. With skills shortages cited by over 50% of manufacturers The Manufacturer / Make UK – AI, Skills and the Future of UK Manufacturing, the best people don't stay on the market long.
