prechecks
Prior verification steps
Prechecks are preliminary examinations or inspections performed before a main activity begins.
Pilots run through prechecks before takeoff; software runs prechecks before installation.
The term appears in technical and procedural contexts where verification prevents problems: The system failed its prechecks and wouldn't boot.
