Where AI can do more

Routine, digitized, and highly repeatable tasks face the greatest pressure.

  1. Read and understand operating manuals, blueprints, and technical drawings.66
  2. Schedule maintenance for industrial machines and equipment, and keep equipment service records.64
  3. Adjust and maintain industrial machinery, using control and regulating devices.64
  4. Overhaul and test machines or equipment to ensure operating efficiency.62
Hardest to automate

Where people still matter

These tasks score lowest on automation feasibility—physical presence, judgement, accountability and real-world variability all resist end-to-end automation.

Beyond AI capability

Adoption and labour-market outlook

Structural factors are kept separate from raw capability so you can see what actually resists automation. Adoption pressure and labour-market resilience are still provisional models—25% of this occupation’s replacement-risk weight rests on them.
