Failure Mode

A failure mode is an event that causes an asset to fail to perform its function. For example, if a pump’s impeller becomes worn, the pump cannot convey liquid at the required rate. When failure mode optimization requires Isograph Availability Workbench, this attribute is mapped to the cause description in AWB.
