Metric
 Calculation
 Unit
 Frequency of Updates
 Remarks
 
Effort Variation (%)
 = ((Actual Effort) - (Planned Effort)) / (Planned Effort) 
x 100
 %
 Weekly
 Actual and Planned Effort as of the date of the report 
should be used.
 
Schedule Variation (%)
 = ((Actual Duration) - (Planned Duration)) / (Planned 
Duration) x 100
 %
 Upon completion of each milestone or Monthly, whichever is 
crossed first.
 Actual and Planned Duration expended to achieve latest 
milestone should be used if update is upon completion of 
milestone. If update is upon completion of a month since 
the last update, the Actual and Planned Duration expended 
to complete the planned scope of work at that point in time 
should be used. 
 
Resource Utilization
 = (FTE Used) / (FTE Billed) x 100
 %
 Weekly
  
 
Rework Effort
 = (Effort for Reviews and Rework on Test Cases) / Effort 
for Test Case Preparation) x 100
 %
 Weekly
 Effort for Test Case Preparation includes Effort for 
Reviews and Rework.
 
Test Cases Prepared per Person Hour
 = (Number of Test Cases Created)/(Effort for Test Case 
Preparation)
 /FTE/hr
 Weekly
 Effort for Test Case Preparation includes Effort for 
Reviews and Rework.
 
Test Cases Executed per Person Hour
 = (Number of Test Cases Executed)/(Effort for Test Case 
Execution)
 /FTE/hr
 Weekly
 Effort for Test Case Execution includes effort for 
reporting.
 
Defect Detection Effectiveness (%)
 = (Number of Defects Reported by Test Team) / (Total 
Number of Defects Reported) x 100
 %
 Weekly
 Total Number of Defects Reported includes defects reported 
by any party other than the test team, including post-
delivery defects.
 
Defect Acceptance Ratio
 = (Number of Defects Accepted as Valid ) /  (Number of 
Defects Reported by Test Team)
 %
 Weekly

Productivity Metrics: say 20 testcases/day

Defect density : Defects identified /kilo lines of code.
