How to calculate Quality of fixes ?

Quality of fixes is the ratio of difference of Total no. of Defects reported as fixed and Total no. of reopened defects to sum of Total no. of Defects reported as fixed and Total no. of new defects due to fix.

Quality of fixes metric is used to determine the quality of fix done by development team. Lower the value indicates the poor quality of defect fixes.

It is measured during each build and end of test execution phase.

How to calculate the Quality of fixes:

Quality of fixes = (Total no. of Defects reported as fixed -Total no. of reopened defects) / (Total no. of Defects reported as fixed + Total no. of new defects due to fix)*100

Example:

Total no. of fixed defects	Total no. of reopened defect	Total no. of new defects due to fix	Quality of fixes
100	5	2	93.13

Quality of fixes = (100-5) / (100+2) * 100

                           = 93.13 %

Risk Identification Efficiency

Risk Identification Efficiency is the ratio of Number of Risk identified to sum of Number of Risk identified and Number of Risk occurred in a project. It determines the efficiency of identifying risk in a project. It helps in planning for the mitigation and contingency to be carried out in a project.

Risk Identification Efficiency is calculated at overall project level.

How to calculated Risk Identification Efficiency:

Risk Identification Efficiency % = (Total no. of Risks Identified) / (Total no. of Risks Identified + Total no. of Risk occurred) * 100

Total no. of Risks Identified	Total no. of Risk occurred	Risk Identification Efficiency %
9	6	60

 

Risk Identification Efficiency % = 9 / (9 + 6) *100

                                                     = 60 %
