ARM 401 Actual Test with Questions &
Answers Passed with Grade A
system safety analysis - ✔✔a safety engineering technique also used as an approach to accident
causation that considers the mutual effects of the interrelated elements of a system on one
another throughout the system's life cycle
conceptual phase - ✔✔a phase in the life of a system when the basic purpose and preliminary
design of the system are formulted
engineering phase - ✔✔a phase in the life of a system when the system's design is constructed
and prototypes are tested
production phase - ✔✔a phase in the life of a system when the actual system is created
operational phase - ✔✔a phase in the life of a system when the system is implemented
disposal phase - ✔✔a phase in the life of a system when the system reaches the end of its useful
life and is disposed of
causal factors - ✔✔the agents that directly result in one event causing another
root cause analysis - ✔✔a process that enables the risk management professional to dig past
the obvious causes of an accident to find other factors that played a role
,RCA process is a systematic way to determine the root cause
fault tree analysis - ✔✔an analysis that takes a particular system failure and traces the events leading
to the system failure backwards in time
failure mode and effects analysis - ✔✔an analysis that reverses the direction of reasoning in the
fault tree analysis by starting with causes and branching out to consequences
failure mode - ✔✔the manner in which a perceived or actual defect in an item, process, or
design occurs
effects analysis - ✔✔the study of failure's consequences to determine a risk events root cause
indenture level - ✔✔an items relative complexity within an assembly, system, or function
local effect - ✔✔the consequences of a failure mode on the operation, function, or status of the
specific item or system level under analysis
next higher level effect - ✔✔the consequence of a failure mode on the operation, function, or status
of the items in the indenture level immediately above the indenture level under analysis
end effect - ✔✔the consequence of a failure mode on the operation, function, or status of
the highest indenture level
criticality analysis - ✔✔an analysis that identifies the critical components of a system and ranks
the severity of losing each component
criticality - ✔✔a product of consequence and occurrence ranking, taken from the risk priority
number calculation, used to determine the relative risk of a failure mode and effects analysis item
, risk priority number - ✔✔the product of rankings for consequences, occurrence, and detection
used to identify critical failure modes when assessing risk within a design process
adding probabilities to a fault tree - ✔✔multiply the numbers
root cause - ✔✔the event of circumstance that directly leads to an occurence
5 why analysis - ✔✔used primarily for problems involving human factors, such as lack of
managerial oversight
asking why repeatedly can help determine its ultimate cause. this process also prevents investigators
from relyingon potentially erroneous assumptions, instead of tracing the problem through a chain of
causality to its origin.
fishbone diagram - ✔✔a 5 whys analysis is the most prevalent method for generating the specific
causes in a fishbone diagram. these causes are depicted as diagonal lines (the fish's bones) connected to
a horizontal arrow (the fish"s spine) that indicates the problem being addressed.
probability analysis - ✔✔a technique for forecasting events, such as accidental and business
losses, on the assumption that they are governed by an unchanging probability distribution
probability distribution - ✔✔a presentation (table, chart, or graph) of probability estimates of
a particular set of circumstances and of the probability of each possible outcome
theoretical probability - ✔✔probability that is based on theoretical principles rather than on
actual experience
empirical probability - ✔✔a probability measure that is based on actual experience through
historical data or from the observation of facts
