Maintainability is defined as the ability of a device to be maintained (preventive maintenance) or restored (corrective maintenance) to its operating condition, with a particular focus on the time required to perform these maintenance operations.

When quantifying this parameter, this capability is expressed as the probability of performing the maintenance operation within a time period no longer than t.
