Certain failures will only occur during operation. HALT and HASS stresses can precipitate intermittent failures that can only be detected if the unit is operating and monitored. Part of the HALT process is to identify the operating limits of thermal, vibration and other stresses. These limits can only be accurately determined when an monitored operating unit begins to malfunction.
