Consider an application that contains errors causing an improper alarm. The consequence of these failures is that the operator must restart the system. An independent' error, how-ever, is also present in the initialization routines executed by the operator. This error does not cause a fault every time the system is restarted. Rather, both the fault and the failure occur as a function of some external parameters set by the operator during the restart procedure. Discuss the correlation between the two types of failures.
