2.2.3.4  Sustainment design review
The sustainment design review is a technical review of the software sustainment 
process design and implementation plan. The review should specify the infrastruc-
ture items and staffing necessary to enable the customer and software support pro-
cesses. The process specifications and design documentation should be baselined 
and the sustainment process organization authorized to execute the implementation 
plan upon final approval.
2.2.3.5  Critical design review
The critical design review (CDR) is a project-level review with stakeholders and 
project management representatives to review the software physical architecture 
and gather feedback on the functional definitions, performance allocations, behav-
iors, data definitions, functional specifications, and plans for the next development 
stage. The PDSS designs may be reviewed at the product CDR or at a separate 
review with a more limited set of stakeholder representatives. The CDR is deter-
mined to be complete when all of the accepted action items or comments generated 
by the review have been satisfactorily resolved.
