AvailabilityDegree to which it is operational and accessible when required
for use. Often expressed as a probability
ReliabilityCapability to maintain a specified level of performance when
used under specified conditions, commonly stated as mean time between failures
(MTBF)
Installability and uninstallabilityCapability to be installed in a specific environment and
uninstalled without altering the environment's initial state
MaintainabilityEase of modification to correct faults, improve performance or
other attributes, or adapt to a changed environment
MonitorabilityExtent to which health and operational data are automatically
collected while operating
OperabilityExtent to which a solution is controlled automatically while
operating
PortabilityCapability to be transferred from one environment to
another
RecoverabilityCapability to reestablish a specified level of performance and
recover the data directly affected in the case of a failure
TestabilityDegree to which the solution facilitates the establishment of
test criteria and the performance of tests to determine whether those criteria
have been met
SupportabilityExtent to which operational problems are
corrected
ReusabilityAbility to repurpose solution components with little
rework
ConformanceAdherence to applicable rules, regulations, policies, and
standards
InteroperabilityCapability to interact with other solutions in the
environment
