Size is typically counted either in Lines of Code or Function Points. Defect Density is used to compare the relative number of defects in various software components. This helps identify candidates for additional inspection or testing or for possible re-engineering or replacement in specific components. Another use for Defect Density is to compare subsequent releases of a product to track the impact of defect reduction and quality improvement activities.
