Commission

When a large mixing console or other device is installed it can be said to be put in to “commission”, or more commonly just “commissioned”, as in, “the console was commissioned”. This is a particular idiom of the word that has been in common use for many years. Commissioning something is the act (or series of actions) of putting something into service formally. It’s a service that is sometimes offered (and required) by makers of large, or technically complex items when they are sold and installed. It may include the full installation (along with some preliminary “make ready” work), testing, training, and some initial tweaking once the item is in service.
