The process of bringing a system, equipment, or facility into working order and testing its functionality. Also refers to formally requesting or authorizing someone to create something, especially artwork or military service.
From Latin 'committere' (to entrust, commit) through Old French 'commission.' The technical sense of testing new equipment developed in the 20th century, while the artistic/military senses are much older.
In engineering, commissioning is like a building's final exam - every system gets tested to make sure it works perfectly before people move in! This process can take months for complex facilities like hospitals or power plants, ensuring safety and efficiency.
