Shakedown
A shakedown or trial run was the testing period undergone by a vessel, or the technology designed to operate such a vehicle, before being declared fully operational. The trial journey, known in nautical terms as the shakedown cruise, was the operation conducted by a new starship and her crew so as to test its systems. It was usually a routine or even a brief ceremonial "maiden voyage", but could also extend to at least one year. A shakedown could reveal flaws inherent in the vessel's construction, especially in prototypes or new technologies.
