Number of defects found in pre-delivery stage agains actual
size of the milestone.
Defect density is a measure of the total known defects
divided by the size of the software .
Number of Known Defects
Defect Density = ---------------------------------
Size
The Number of Known Defects is the count of total
defects identified against a particular software entity,
during a particular time period.
Use for Defect Density is to compare subsequent
releases of a product to track the impact of defect
reduction and quality improvement activities.

Defect density is one of the most important factors that allow one to decide if a piece of software is ready to be released.
One of the easiest ways to judge whether a program is ready to release is to measure its defect density—the number of defects per line of code.
Defect Density is the number of confirmed defects detected in software/component during a defined period of development/operation divided by the size of the software/component.
In theory, one can find all the defects and count them, however it is impossible to find all the defects within any reasonable amount of time.
Estimating defect density can become difficult for high reliability software, since the remaining defects can be extremely hard to test.
Defect seeding will work only if the distribution of seeded defects is similar to the existing.
DEFECT DENSITY FORMULA:
Defect Density = Number of Defects
_______________________
Size
USES:
1. For comparing the relative number of defects in various software components so that high-risk components can be identified and resources focused towards them.
2. For comparing software/products so that ‘quality’ of each software/product can be quantified and resources focused towards those with low quality.
