Metrices

1) Schedule variance = (Actual time taken - Planned time) / Planned time * 100

2) Effort variance = (Actual effort - Planned Effort)/Planned effort * 100

3) Defect unearthing efficiency = 100 * STRs found in pass 1/ ( STRs found in pass 1 + STRs found in pass 2 but existing in pass 1) = Defect unearthing efficiency for pass 1.

Thus defect unearthing efficiency can be found for all passes.

Also defect unearthing efficiency in terms of field STRs could be found as follows:

= 100 * Total STRs found in Polaris for a release/ (Total STRs found in Polaris for a release + Field STRs for that release)

4) Test case efficiency = (Total STRs - STRs not mapped)/Total STRs * 100

5) Test case coverage = (Total Test cases - STRs that cannot be mapped to test cases)/ Total Test Cases * 100

PRODUCTIVITY METRICS

1. OUTPUT / INPUT OR

VALUE OF MATERIAL / COST OF PRODUCTION

Eg: Non Commented Software Source (NCSS) Per Engineer Per Month

NCSS per Person Month

NCSS per Function Point

NCSS can also be replaced by KLOC (Kilo Lines of Code)

QUALITY METRICS

1. DEFECTS PER KLOC

2. DEFECTS PER FUNCTION POINT

3. % OF MAINTENANCE / PROJECT EFFORT

4. POST RELEASE STABILITY

5. PREDELIVERY DEFECT REMOVAL EFFICIENCY

6. DELIVERED DEFECTS PER KLOC

7. (COST OF REWORK / TOTAL COST ) X 100

PROCESS IMPROVEMENT METRICS

1. PROCESS IMPROVEMENT OR OVERALL EFFICIENCY = RETURN ON INVESTMENT

2. % OF RECYCYLED CODE

3. % OF CALENDER TIME / PHASE

4. INCREASED RETURNS / INCREASED COST

5. % OF DEFECTS IN PHASE OF THIS YEAR / % OF DEFECTS IN PHASE OF LAST YEAR

6. DIFFICULTY COMPLEXITY = McCABE COMPLEXITY

7. TOTAL RECORDED PRE-DELIVERY DEFECTS / TOTAL FOUND DURING UAT

8. POST RELEASE DISCOVERED DEFECTS DENSITY OVER PERIOD
