What are different types of general metrics? Continued...

- Design To Requirements Traceability
this metric provides the analysis on the number of design elements matching requirements to the number of design elements not matching requirements. It is calculated at stage completion and calculated from software requirements specification and detail design.

Formula:
Number of design elements.
Number of design elements matching requirements.
Number of design elements not matching requirements.

- Requirements to Test case Traceability
This metric provides the analysis on the number of requirements tested vs the number of requirements not tested. It is calculated at stage completion. It is calculated from software requirements specification, detail design and test case specification.

Formula:
Number of requirements.
Number of requirements tested.
Number of requirements not tested.

- Test cases to Requirements Traceability
This metric provides the analysis on the number of test cases matching requirements vs the number of test cases not matching requirements. It is calculated at stage completion. It is calculated from software requirements specification and test case specification.

Formula:
Number of requirements.
Number of test cases with matching requirements.
Number of test cases not matching requirements.

- Number of defects in coding found during testing by severity
This metric provides the analysis on the number of defects by the severity. It is calculated at stage completion. It is calculated from bug report.

Formula:
Number of defects.
Number of defects of low priority.
Number of defects of medium priority.
Number of defects of high priority.

- Defects - state of origin, detection, removal
This metric provides the analysis on the number of defects by the stage of origin, detection and removal. It is calculated at stage completion. It is calculated from bug report.

Formula:
Number of defects.
Stage of origin.
Stage of detection.
Stage of removal.

- Defect Density
This metric provides the analysis on the number of defects to the size of the work product. It is calculated at stage completion. It is calculated from defects list and bug report.
Formula:
Defect Density = [total number of defects/Size(FP/KLOC)] *100
