How AI is applied to this activity group

Microsoft's "Working with AI" study measured how often an AI assistant performs each work activity in real Bing Copilot conversations. Averaged across the 6 intermediate activities under Repairing and Maintaining Mechanical Equipment that the study measured, this group ranks in the 31st percentile for how frequently AI is applied — a description of how AI is used today, not a forecast that the activity will be automated.

The figure is the mean of the child activities' applied-percentiles; open any activity above to see its underlying Microsoft measurements. Every occupation blends many activities, so a high AI-applied rank for one group does not mean a job is being automated.
