Which of the following would be the BEST population to take a sample from when testing program
changes?
A.
Test library listings
B.
Source program listings
C.
Program change requests
D.
Production library listings
Explanation:
The best source from which to draw any sample or test of system information is the automated
system. The production libraries represent executables that are approved and authorized to process
organizational datA . Source program listings would be timeintensive . Program change requests are
the documents used to initiate change; there is no guarantee that the request has been completed
for all changes. Test library listings do not represent the approved and authorized executables.
