What does commissioning mean?
Commissioning is the act of formally ordering, authorizing, or bringing something into service. Its most prominent sense is technical and ceremonial: the commissioning of a ship marks the moment a newly built vessel enters active service, while in construction and engineering, commissioning refers to the systematic testing and verification that installed systems work as intended before handover to a client. The word equally covers the world of patronage and procurement — the commissioning of an artwork, a portrait, a report, or a scientific study — where one party engages another to produce something specific. Derived ultimately from Latin via Old French "commission," it carries a formal, official connotation and appears most often in military, industrial, architectural, and institutional language. Its natural opposite is decommissioning, the process of taking something out of service, making the pair a tidy linguistic bookend for the working life of ships, plants, and equipment alike.
The act or process of ordering, authorizing, or formally placing something into service or operation, especially a ship, building, or system.

Etymology of commissioning
Commissioning derives from "commission," which entered English in the late medieval period from Old French "commission," itself from Latin "commissio," meaning "a sending together, entrusting," formed from "com-" (together) and "mittere" (to send). The noun "commissioning" arose by derivation from the verb "commission," which developed its senses of formally appointing, ordering, and placing into service from the sixteenth century onward. It shares its Latin root "mittere" with cognates such as "missile," "mission," "message," and "admit."
