Do the verification, design, and specification
documentation correlate? Results of Review —As a result of a successful
DCR, the end item design is approved for production. All
open issues should be resolved with closure actions and
Functional and Physical Configuration Audits. The
Physical Configuration Audit (also known as a configuration inspection) verifies that the physical configuration of
the product corresponds to the "build-to" (or ''code-to")
documentation previously approved at the CDR. The
Functional Configuration Audit verifies that the
acceptance test results are consistent with the test
requirements previously approved at the PDR and CDR.
It ensures that the test results indicate performance
requirements were met, and test plans and procedures
were executed correctly. It should also document
differences between the test unit and production unit,
including any waivers.
4.9 Status Reporting and Assessment An important part of systems engineering
planning is determining what is needed in time,
resources, and people to realize the system that meets
the desired goals and objectives. Planning functions,
such as WBS preparation, NASA Systems Engineering Handbook
Management Issues in Systems Engineering
scheduling, and fiscal resource requirements planning,
were discussed in Sections 4.3 through 4.5. Project
management, however, does not end with planning;
project managers need visibility into the progress of
those plans in order to exercise proper management
control. This is the purpose of the status reporting and
assessing processes. Status reporting is the process of
determining where the project stands in dimensions of
interest such as cost, schedule, and technical
performance. Assessing is the analytical process that
converts the output of the reporting process into a more
useful form for the project manager -- namel...
