Which of the following is a technique that provides a systematic description of the combination of
unwanted occurrences in a system?
A.
Sensitivity analysis
B.
Scenario analysis
C.
Fault tree analysis
D.
Cause and effect analysis
Explanation:
Fault tree analysis (FIA) is a technique that provides a systematic description of the combination of
possible occurrences in a system, which can result in an undesirable outcome. It combines
hardware failures and human failures.
Answer B is incorrect. This analysis provides ability to see a range of values across several
scenarios to identify risk in specific situation. It provides ability to identify those inputs which will
provide the greatest level of uncertainty.
Answer D is incorrect. Cause-and-effect analysis involves the use of predictive or diagnostic
analytical tool for exploring the root causes or factors that contribute to positive or negative effects
or outcomes. These tools also help in identifying potential risk.
Answer A is incorrect. Sensitivity analysis is the quantitative risk analysis technique that:
Assist in determination of risk factors that have the most potential impact Examines the extent to
which the uncertainty of each element affects the object under consideration when all other
uncertain elements are held at their baseline values
