Explain 'Software metrics'?

Measurement is fundamental to any engineering discipline

Why Metrics?

- We cannot control what we cannot measure!

- Metrics helps to measure quality

- Serves as dash-board

 

The main metrices are :size,shedule,defects.In this there are main sub metrices.

 

Test Coverage = Number of units (KLOC/FP) tested / total size of the system

Test cost (in %) = Cost of testing / total cost *100

Cost to locate defect = Cost of testing / the number of defects located

Defects detected in testing (in %) = Defects detected in testing / total system defects*100

Acceptance criteria tested = Acceptance criteria tested / total acceptance criteria
