2.2.2.5  Preliminary design review
The preliminary design review (PDR) is a project-level review with stakeholders 
and project management representatives to review the software functional archi-
tecture, and gather feedback on the functional definitions, performance allocations, 
behaviors, data definitions, functional specifications, and plans for the next devel-
opment stage. The PDSS process specification(s) may be reviewed at the product 
PDR or at a separate review with a more limited set of stakeholder representatives. 
The PDR is determined to be complete when all of the accepted action items or 
comments generated by the review have been satisfactorily resolved.
