7.4 C/SSR data elements will reflect the output of the contractor's C/SSR management
procedures (refer to DFARS 252.242-7005). The definitions of terms contained in the
Cost/Schedule Control Systems Criteria (C/SCSC) (refer to DFARS 252.242-7001) may be used as
guidance in completing Columns (2) through (9) of the C/SSR with the exception of the
definitions for Budgeted Cost for Work Scheduled (BCWS) and Budgeted Cost for Work Performed
Application of the C/SSR does not invoke the unique requirements or disciplines of
the C/SCSC, such as the use of work packages for determining BCWP. The contractor may use
C/SCSC compliant practices if they constitute the contractor's normal way of doing business.
The method of deriving the BCWP will be left to the discretion of the reporting contractor
and will be subject to negotiation, if necessary, and inclusion in the contract. While the
contractor must be in a position to explain the method used for determining the BCWP, the indepth
demonstration review referred to in DFARS 252.242-7001 will not be required.
