Error Severity Metrics

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:

Errors Code Testing Development

 

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
