AI-first for manufacturers

Checkable evidence from the factory floor exists but is thin. Two field studies measured AI in quality work, at Siemens and at Hitachi Energy, both large companies. Most other figures on maintenance, quality and engineering are the companies’ own.

Where AI helps

WorkWhat has been shown or reportedWhere it comes from
Finding the cause of scrapAt a Hitachi Energy chip plant, an AI model pointed to two process steps that were spoiling chips. A controlled test cut yield loss by 21.7%. On a second product it fell by 51.3%.Hitachi Energy case. A peer-reviewed field study.
Visual inspectionAt a Siemens electronics factory, inspectors who saw where the AI had spotted a problem caught 93% of defective boards. Inspectors given only the AI’s score caught 82%, fewer than the AI alone.Siemens case. A peer-reviewed experiment with 48 factory workers.
Quoting and costingAt Herges, a steel fabricator, an AI model’s estimates of production time were five times closer to the real figure than those of experienced staff. EIST, a six-person metalworking shop, reports quotes in about 10 minutes that used to take up to two hours.Herges case, measured by a public support centre. EIST case, the owner’s own estimate.
Product developmentAt Procter & Gamble, one person with AI produced product ideas as good as a two-person team without it, in about 16% less time.Procter & Gamble case. An experiment, not yet peer-reviewed.
Sales, marketing and administrationEU manufacturers that use AI apply it most often to marketing and sales (30%) and to business administration (27%).Eurostat, official statistics
Engineering softwareSiemens added AI agents to its engineering assistant in 2025. One customer, thyssenkrupp Automation Engineering, reports better code quality and faster development. No figures were given.Company announcement
MaintenanceRolls-Royce says digital models of its aircraft engines extended the time between maintenance for some engines by up to 50%.The company’s account, in a 2021 press report
Keeping production running in a crisisAmong 237 German manufacturers, those more ready for AI coped better with the Covid-19 lockdowns. The effect appeared only above a certain level of readiness.Peer-reviewed survey study (Lerch and others, 2022)

No controlled test yet for maintenance and production staff. No published controlled study from 2025 or 2026 has tested generative AI with maintenance or production workers. The figures in the table on maintenance and engineering are the companies’ own.

Inspectors’ own skill can fade. In a study at four endoscopy centres in Poland, doctors found pre-cancerous growths in 28.4% of colonoscopies done without AI before AI was introduced. Three months after it was introduced, the rate without AI was 22.4%. Staff who inspect alongside AI every day may lose the skill they need when the AI fails. Test inspectors without the AI now and then. See the Siemens case.

Size matters less than skills. In Germany, 20% of small and medium-sized firms used AI in 2022–2024, from 19% of firms with fewer than five employees to 36% of firms with 50 or more. Once the state development bank KfW took account of graduates employed, innovation, research and a digital strategy, size and sector mattered little.

A plan is not a result. In 2025 Volkswagen said it would invest up to €1 billion in AI by 2030 and expected savings of up to €4 billion by 2035. See what does not count as evidence.

Maturity scores are common here. Researchers have published AI maturity models for smart manufacturing and for the process industry. A commercial index for industry, AIMRI, is run by a paid, certified assessor and is not a self-assessment. A score describes where you stand. It has not been shown to predict results. See do not treat a maturity score as a forecast.

Risks and rules

  • AI that keeps a machine safe. In the EU, the AI Act classes an AI system as high-risk when it is a safety component of a product covered by listed EU product-safety laws, and that product must be checked by an outside body before sale. A safety component is a part whose job is to keep the product safe. This classification applies from 2 August 2028.
  • Machinery is handled through its own law. A 2026 amendment moved the Machinery Regulation to a separate part of that list. For products in that part, most of the AI Act’s own requirements do not apply directly. The requirements come through the product law instead. Ask your machine supplier which rules apply to your equipment.
  • AI that only improves performance. The amended Act says AI used only for things like performance optimisation, automation or quality control is not a safety component. There is one exception: if its failure would endanger health and safety, it counts as one.
  • AI that manages workers. In the EU, AI used to allocate tasks based on a person’s behaviour or traits, or to monitor and evaluate workers’ performance, is on the high-risk list. So is AI used in recruitment. These rules apply from 2 December 2027. The Act allows some exceptions, for example for narrow procedural tasks. In a survey of workers across the EU by the European Commission’s Joint Research Centre, 24% had their work schedules set by an algorithm. Where such a system set the pace of the work, workers reported higher stress.
  • People still do the physical work. AI reaches office and engineering tasks first. Map tasks before you set targets. See map tasks before deciding what to automate and the worked example below.

Practices for this industry

All 30 practices in the library apply in this industry. None of them is specific to one sector. For the ones below, a study, a company case or a worked example from this sector shows why they matter here.
