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

- Review Effectiveness
This metric will indicate the effectiveness of the review process.It is calculated at the completion of review or completion of testing stage. It is calculated from peer review report, peer review defect list and bugs reported by testing.
Formula:
Review Effectiveness = [(Number of defects found by reviews)/((Total number of defects found y reviews)+Testing)] * 100

- Total number of defects found by reviews
This metric will indicate the total number of defects identified by the review process. the defects are further categorized as high, medium or low. It is calculated at completion of reviews. It is calculated from peer review report and peer review defect list.

Formula: Total number of defects identified in the project.

- Defect vs Review Effort - Review Yield
This metric will indicate the effort expended in each stage for reviews to the defects found. It is calculated at completion of reviews. It is calculated from peer review report and peer review defect list.

Formula : Defects/Review Effort

- Requirements Stability Index (RSI)
This metric gives the stability factor of the requirements over a period of time, after the requirements have been mutually agreed and base lined between company and the client. It is calculated at stage completion and project completion. It is calculated from change request and software requirements specification.

Formula:
RSI = 100 * [(Number of base-lined requirements)-(Number of changes in requirements after the requirements are base-lined)]/(Number of base-lined requirements)

- Change Requests by State
This metric provides the analysis on state of the requirements. It is calculated at stage completion. It is calculated from change request and software requirements specification.
Formula:
Number of accepted requirements, Number of rejected requirements, Number of postponed requirements.

- Requirements to Design Traceability
This metric provides the analysis on the number of requirements designed to the number of requirements that were not designed. It is calculated at stage completion. It is calculated from software requirement specification and detail design.
Formula:
Total number of requirements, Number of requirements designed, Number of requirements not designed.
