Acceptance testing conducted at the site at which the product is developed and performed by employees of the supplier organization, to determine whether or not a component or system satisfies the requirements, normally including hardware as well as software.
Test is considered to be failed if the actual result does not match the expected result.
Testing by simulating failure modes or actually causing failures in a controlled environment.
Deviation of a component or system performance, operation or resultfrom the expected one.
Systematic approach to determination and analyzing of risks of identification of possible types of failures and attempt to prevent them.
Extension of FMEA; in addition to the basic FMEA it includes an analysis of criticality, which used to display the probability of types of failures with respect to the criticality of their consequences. The result reflects the type of failure with a high probability and criticality of the consequences, allowing corrective action, where they will have the greatest value.
It is the ratio of the number of failures in this category to a given unit of measure.
Test result, which has reported an error, but in fact there is no defect in the object of testing.
Test result, which was unable to determine the presence of a software bug really existing in the object of testing.
