</TABLE></div> <div> <B>Coverage Status</B></div> <div> Figure 5</div> <bR> <div> In this example, the first column lists the high level requirements.  The second column lists the number of testable requirements associated with the corresponding high level requirement.  The third column lists the number of testable requirements that are validated by test cases.  The fourth column lists the percentage of testable requirements that are "covered" by test cases.  This measure of requirements coverage is a very powerful measure and gives important insight into the adequacy of the testing.</div> </td> </tr><tr> <td valign="top" colspan=2 height=24 BGCOLOR="#FFFFFF" TEXT="#080000"> <div> <A HREF="quant_unders_req.htm" TARGET="_top" TITLE="Quantifying Understanding of
