In reference to No. 2, answer No. 1 is correct for the
specfic system under consideration. Pertaining to programs
initially software in development is going to be written
with some purpose and direction and very often now as an
improvement over an earlier version. So with this in mind,
testing and benchmarks for performance should be considered
during development. Initial trials (pre-shakedown) should
test portions for accuracy and stability. Functions and
controls would be checked and fixed if in error. Once a
system is considered operable, shakedown testing could
proceed.
Earlier benchmarks and tests, plus older version
performance on similar work would have been evaluated to
measure current against. Perfect condidtion operations
would be input to check for apparent operations. (That is
it would be checked under somewhat easy conditions to see
if it is working as designed for. Like test driving a car
from a showroom floor, nothing hard yet, just taking it out
for a spin.) Next would be performance testing in
predesigned tests determined ahead to see if it will work
under increasingly difficult conditions, basically, how far
will it go before failure.
Almost any system can fail if overloaded. Shakedown
testing is done to determine if the item is suitable for
the needs of the end user under conditions they would or
might possibly encounter. The more critical the potential
loss from failure, the greater and deeper testing must be
performed. Military,goverment, public safety, flight
systems,marine, medical systems, infrastructure etc. need
to undergo rigorous testing and shakedown as compared to
non-critical systems such as software for a college
classroom. this applies to software and hardware.
