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

- Overall Review Effectiveness
This metric will indicate the effectiveness of the testing process in identifying the defects for a given project during the testing stage. It is calculated at monthly basis and after build completion or project completion. It is calculated from test reports and customer identified defects.

Overall Test Effectiveness OTE = [(Number of defects found during testing)/(Total number of defects found during testing + Number of defects found during post delivery)] *100

- Effort Variance (EV)
This metric gives the variation of actual efforts vs. the estimated effort. This is calculated for each project stage. It is calculated at stage completion as identified in SPP. It is calculated from estimation sheets for estimated values in person hours, for each activity within a given stage and actual worked hours values in person hours.

EV = [(Actual person hours - Estimated person hours)/Estimated person hours] * 100

- Cost Variance (CV)
This metric gives the variation of actual cost vs the estimated cost. This is calculated for each project stage. It is calculated at stage completion. It is calculated from estimation sheets for estimated values in dollars or rupees for each activity within that stage and the actual cost incurred.

CV = [(Actual Cost-Estimated Cost)/Estimated Cost] * 100

- Size Variance
This metric gives the variation of actual size vs the estimated size. This is calculated for each project stage. It is calculated at stage and project completion. It is calculated from estimation sheets for estimated values in function points or KLOC and from actual size.

Size Variance = [(Actual Size-Estimated Size)/Estimated Size] * 100

- Productivity on Review reparation - Technical
This metric will indicate the effort spent on preparation for review. This is to use this to calculate for languages used in the project.It is calculated at monthly or after build completion. It is calculated from peer review report.

For every language used, calculate
(KLOC or FP)/hour(*Language) where Language - C,C++, Java,XML etc...

- Number of defects found per review meeting
This metric will indicate the number of defects found during the review meeting across various stages of the project. It is calculated at monthly or after the completion of review. it is calculated from peer review report and peer review defect list.

Formula : Number of defects/Review Meeting

- Review Team Efficiency(Review Team Size Vs Defects Trend)
This metric will indicate the review team size and the defects trend. This will help to determine the efficiency of the review team. It is calculated at monthly and completion of review. It is calculated from peer review report and peer review defect list.

Formula : Review team size to the defects trend.
