means The formal process of testing, adjusting, and verifying a newly built system so it actually performs as designed before it's handed over for real use.

from Traces back to Latin committere, 'to bring together, entrust,' via commissio, 'a sending forth or connecting.' English borrowed 'commission' in the 1400s for an official charge or task given to someone — the sense of empowering something to act. The verb 'to commission' later extended to ships and machinery: a commissioned vessel was formally put into active service. By the 20th century, engineers stretched it further to mean the whole ritual of bringing a plant, building, or system up to working order — entrusting it, at last, with the job it was built for.
