Software audits should be conducted prior to the CDR to ensure the software 
products and architectural artifacts are complete and have incorporated approved 
change proposals and requests. The following audits should be conducted:
1. 
Structural configuration audit
.
 Tracing structural element requirements to the 
functional units it assimilated. Ensuring integration tests do not repeat testing 
conducted at lower levels of the configuration unless warranted. Ensures that all 
internal software interfaces are adequately addressed throughout the software 
integration strategy.
2. 
Software test audit.
 Tracing each test case and procedure to the software specifi-
cation requirements it is supposed to validate. A software test may affect one or 
more of the software specifications (software product, computing environment, 
and interface), and this should be properly reflected in the requirements trace-
ability matrix.
3. 
Corrective action audit.
 Tracing each authenticated change request or proposal 
to its corrective action disposition. This audit must ensure that the corrective 
action was properly accomplished and is reflected in the affected software prod-
uct and architectural artifacts.
