the.com/utilization

means The measured rate at which your available time or capacity is actually put to productive use.

from From Latin 'uti,' meaning to use, which gave French 'utiliser' and eventually English 'utilize' around the early 1800s — a word 19th-century writers initially sneered at as an ugly, needless import before it settled into respectable (if slightly bureaucratic) use. 'Utilization' followed as the noun form, and found its true calling in the 20th century inside efficiency reports and spreadsheets, where it still lives.
