Reliability, Availability, Maintainability (RAM)
RAM is the assessment of the inherent reliability of an item or system,
- Reliability: how long it can be expected to operated before failure, based on the individual components from which it is comprised
- Availability: its expected or required availability for operations, and
- Maintainability: the maintenance time and complexity of repair of individual items,
which are then used to determine redundancy requirements, equipment quantity and maintenance resources required.
