what are the metrics in general we use in testing...

Metric
Calculation
Unit
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

Usually Test Strategy consists of Testing Measurements &
Metrics

This explains with what efficiency and speed testing can be
done.
This can be estimated by three metrics
1.Testing Team Measurements/Metrics (TTM): It explains how
much testing is finished & yet to finish
2.Quality Assurance Measurements/Metrics (QAM): It explains
how much Quality is expected.
3.Process/Project Capability Measurements/Metrics(PCM):
This PCM is analyzed ofr Maintenance Projects so, not used
for all projects
