Each assertion listed in the Technical Recovery Checklist is supported by a

Cause Description. Each Cause Description broadens and deepens the understanding

of the checklist assertion and provides a recovery from the issue raised

by the assertion. Following are explanations of the assertions found in the Technical

Recovery Checklist.
