identify the work processes to be used to implement the change, and
identify any constraints to the implementation process.
An individual or group other than the one that developed the package must perform the
review of the change control package. A modification or construction package may be
used to further define implementation instructions.
5.5.3 Deviating from or Making Changes to the Change Control Package.
Changes should be implemented consistent with the change control package. The design
authority must identify, review, and approve any deviations from, or changes to, the
change control package prior to implementation. Contractor procedures must define this
process (often called field change requests or FCRs) and the authority levels. FCRs
should receive technical and management reviews commensurate with those of the
original package and the approval authority level should be at the same level as the
original change. Following evaluation and approval by the design authority, field change
notices (FCNs) should be issued that revise the work processes consistent with the
In addition, if the contractor identifies any nonconforming items while implementing a
change, the contractor should document the nonconformance in a nonconformance report
(NCR). The NCR should be reviewed to verify that it:
(1) meets design criteria and assumptions and
(2) is consistent with the analyses.
The review and disposition of NCRs must be documented and retained.
5.5.4 Tracking Changes to Completion
Consideration should be given to assigning an individual the responsibility for tracking
physical change status and ensuring that the change is completed in accordance with the
change control package. Contractors have successfully used Cognizant System
Engineers or dedicated configuration management specialists to perform this function.
5.5.5 Reporting Implementation Progress
The contractor should consider issuing periodic progress reports on the implementation
of major changes. These reports should:
