What is defect density explain the formula?

Defect Density is the number of defects confirmed in software/module during a specific period of operation or development divided by the size of the software/module. It enables one to decide if a piece of software is ready to be released. Defect density is counted per thousand lines of code also known as KLOC.Click to see full answer. Just so, what is defect density?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. ELABORATION. The ‘defects’ are: confirmed and agreed upon (not just reported). Dropped defects are not counted. how do you calculate defects? The formula for defect rate is the amount of defective products observed divided by the number of units tested. For example, if 10 out of 200 tested units are defective, the defect rate is 10 divided by 200, or 5 percent. Defect rate is often stated in terms of defects per million. Beside above, how do you calculate defect density in agile? Defect Density = Total Defect/Size. Hence, following are the steps for calculating defect density: Collect the raw material, i.e., testers will require the total number of defects detected while developing the software product. Calculate the average number of defects/ Functional area or line of code (LOC).How can defect density be reduced?The defect density can be optimized by effective distribution of size of modules. The larger modules can be broken into smaller modules and smaller modules can be merged to minimize the overall defect density.
