Reliability can be a performance metric. If you say your system will perform as specified 99% of the time, that defines the reliability of your system in the form of a performance metric. If you say your system works most of the time or works better than system B, that is not a performance metric. To be a reliability metric, you have to relate reliability to a number scale.

Yes. It is achieved by using high reliability parts, design redundancy, and a fail operational-fail save design philosophy. Metrics are determined by statistical analysis coupled with rigorous environmental testing.

The inverse of reliability is mean-time-before-failure (MTBF). You generally want a higher MTBF for your products, otherwise if they don't last very long people will not buy them.
