commissioning
試運転 / 委託
解説 Definition
commissioning は commission（委託する、稼働できる状態にする）の動名詞・現在分詞に由来する名詞です。設備やシステムの試運転・稼働準備を指すほか、仕事や作品を正式に依頼することも表します。
Commissioning is the process of formally requesting and authorizing a person to produce a work or perform a task. In engineering, it is the systematic testing, adjustment, and verification of equipment or a system before or during its entry into operation.
覚え方のコツ Memory Tip
commissioning は commission＋-ing で、動名詞由来の名詞です。「正式に任務を与える」が共通像で、人に報告書や作品を依頼する commissioning と、設備を検査・調整して稼働可能にする commissioning に分かれます。commissioning a report と commissioning of a machine／system の型を対にして覚えます。
Connect commissioning to commission plus -ing and keep one shared idea: formally giving something a role or assignment. When a report, artwork, or study is commissioned, someone officially requests and pays for its production. In engineering, commissioning prepares a machine, building system, or facility to perform its assigned function through inspection, testing, adjustment, and verification. Learn the two patterns together: commissioning a report from an expert and the commissioning of a new machine. In the technical sense, it is broader than a single test run because it confirms that the whole installation is ready to operate as intended.
例文
The commissioning of the new machine took two weeks.

Commissioning a report from an expert can be expensive.

commissioning の語源・成り立ち Etymology
ラテン語 committere（委ねる）から派生した commission（委任・任務）に動名詞語尾 -ing が付いた語。com-（共に）+ mittere（送る）で「任務を託す」が原義。関連語: commit（委ねる）、mission（使命）。機械の「試運転」は、正式に任務を引き渡す＝稼働を委ねる行為から。
Commissioning is formed from commission and -ing. Commission came through Old French from Latin commissio, “a sending together” or “entrusting,” derived from committere, “to join, entrust, or commit,” combining com- and mittere, “to send.” The sense of formally entrusting a task led to commissioning a work. Its engineering use developed from formally placing equipment or a system into service after checks and preparation.
