The defect density is calculated by dividing the ‘total defects’ of software by its ‘Size. ‘ Defect Density = Total Defect/Size. According to best practices, one defect per 1000 lines (LOC) is considered good.

What is defect density?

Definition: Defect density can be defined as the number of confirmed bugs in a software application or module during the period of development, divided by the size of the software. Defect density is counted per thousand lines of code, also known as KLOC.

What is defect density in semiconductor?

The defect density (D0) of a process is the number of defects per die that are large enough to become killer defects per unit area.
