CQPA Practice Exam 2 (V, VI, VII) – Study Guide and Practice Questions for
Quality Process Analyst Certification
Parameter - correct answer ✔✔True numeric population value, often unknown, estimated by a
statistic
Population - correct answer ✔✔All possible observations of similar items from which a sample
is drawn
Statistic - correct answer ✔✔A numerical data value taken from a sample that may be used to
make an inference about a population
MIL-STD-721C (1981) - correct answer ✔✔Considered by reliability professionals as the
"dictionary" for reliability and maintainability terms
Accessibility - correct answer ✔✔A measure of the relative ease of admission to the areas of an
item for the purpose of operation or maintenance
Availability - correct answer ✔✔A measure of the degree to which an item is in an operable and
committable state at the start of a mission when the mission is called for at an unknown
(random) time
Burn-in - correct answer ✔✔The operation of an item under stress to stabilize its characteristics
Checkout - correct answer ✔✔Tests of an item to determine its condition or status
Corrective Action - correct answer ✔✔A documented design, process, procedure, or materials
change implemented and validated to correct the cause of failure or design deficiency
, Criticality - correct answer ✔✔A relative measure of the consequences of a failure mode and its
frequency of occurances
De-bugging - correct answer ✔✔a process to detect and remedy inadequacies
Dependability - correct answer ✔✔A measure of the degree to which an item is operable and
capable of performing its required function at any (random) time during a specified mission
profile
Derating - correct answer ✔✔(a) using an item in such a way that applied stresses are below
rated values
(b) The lowering of the rating of an item in one stress field to allow an increase in another stress
field
Durability - correct answer ✔✔A measure of useful life (a special case of reliability)
Environment - correct answer ✔✔The aggregate of all external and internal conditions (such as
temperature, humidity, radiation, magnetic and electric fields, shock vibration, etc.)
Environmental Stress Screening (ESS) - correct answer ✔✔A series of tests conducted under
environmental stresses to disclose weak parts and workmanship defects for correction
Failure - correct answer ✔✔The event, or inoperable state, in which any item or part of an item
does not perform as previously specified
Failure Analysis - correct answer ✔✔Subsequent to a failure, the logical systematic examination
of an item, its construction, application, and documentation to identify the failure and
determine the failure mechanism
