Appendix A. Example Verification Cross Reference Matrix
The following table is an example of a verification cross reference matrix (VCRM) from a system test plan. The requirements listed in the example are for the video subsystem only and include the system specification requirement statement, the paragraph reference number (with "shall" statement number in parenthesis if more than one requirement is included in the reference paragraph), and the verification method(s) (Inspection, Certification of Compliance, Analysis, Demonstration, and Test). These first three columns of the matrix appear in the system specification and are referred to in that document as the requirements verification matrix. The last three columns: test level (1, 2, 3, 4 or 5), test responsibility (who is responsible for verifying the requirement), and test identification number (i.e., which specific test(s)-in this case at system level 4 or 5-will verify the requirement) are added in the system test plan to complete the VCRM.
