Test mechanical equipment to ensure proper functioning.
Detailed work activity
Test mechanical equipment to ensure proper functioning. is a detailed work activity in O*NET — a concrete unit of work shared across 29 occupations and seen in 35 occupation-specific tasks. It rolls up into the broader work activity Test performance of equipment or systems. in Inspecting Equipment, Structures, or Materials .
Detailed work activities are the most granular shared layer in O*NET's work-activity hierarchy (Generalized → Intermediate → Detailed → occupation-specific task). The figures below describe how this activity shows up across the economy and what independent studies measure about AI and this kind of work — not a prediction that the work will be automated.
AI exposure
Of the 35 tasks under this activity that the OpenAI / Eloundou “GPTs are GPTs” study rated, 2 (6%) are flagged as directly exposed to language models (E1) or exposed via model-powered tools (E2).
The Anthropic Economic Index observes real AI use on 3 of these tasks, with a mean mapped-usage share of 0.002% per task.
Exposure estimates overlap with model capabilities — whether a model could speed the task up — not whether the work will be done by software. Observed AI use is augmentation and assistance today, not jobs replaced.
