What does utilization mean?
Utilization (British English: utilisation) is the noun for the act of using resources, equipment, or available capacity, often with the suggestion that the use is effective or productive. In business and technology, it commonly appears in measures such as capacity utilization and resource utilization, where it describes how much of an available asset or workforce is actually put to use. The word can sound formal and managerial, making it useful when discussing efficiency, but its meaning does not always imply optimal performance: a low utilization rate, for example, shows that much available capacity remains unused. In everyday writing, “use” or “usage” is usually simpler and more neutral. Utilization is chiefly a noun in modern English; “utilize” is the corresponding verb, and “utilized” is its past tense and past participle. The word ultimately comes from Latin utilis, meaning “useful,” the same root behind “utility” and “utilitarian.”

Where does utilization come from?
Utilization was formed in English during the 19th century from utilize plus the noun-forming suffix -ation. Its deeper root is the Latin utilis, meaning “useful,” which also underlies utility and utilitarian. Through English derivatives such as utility and utilize, this root came to express practical use or effective employment.
