Overview

In this post, we will calculate the Error Severity metrics. The project information, error distribution numbers and the errors weights can be found at:

Sample Defect Weights

Average Severity of Code Errors(ASCE)

ASCE = $\huge \frac{WCE}{NCE}$

WCE= Weighted errors detected by Code inspection & Testing.

NCE= number of errors detected by Code inspection & Testing.

WCE = $\huge 21*(2) + 12*(5) + 7*(10) = 172$

NCE = $\huge 40$

ASCE = $\huge \frac{172}{40}$ = $\huge 4.3$

Average Severity of Development Errors(ASDE)

ASDE = $\huge \frac{WDE}{NDE}$

WDE= Weighted errors detected by Development & Design.

NDE= number of errors detected by Development & Design.

WDE = $\huge 6*(2) + 7*(5) + 2*(10) = 67$

NDE = $\huge 15$

ASDE = $\huge \frac{67}{15}$ = $\huge 4.47$
