RAMS is an acronym for Reliability, Availability, Maintainability, and Safety. These four properties are considered important attributes of technical systems.[1]

Reliability denotes a product or system’s ability to perform a specific function and may be given as design reliability or operational reliability.

Availability denotes the ability of a system to be kept in a functioning state.

Maintainability is determined by the ease at which the product or system can be repaired or maintained.

Safety denotes what risk it is for harming people, the environment, or any other assets during a system's life cycle.
