Discover the total lines of codeĮach module within your program or software contains a certain number of lines of code. For example, if you had three bugs in module one and six bugs in module two, you would have a total of nine defects. Add each defect, or bug, found in each module together to find the total number of defects. Once you've determined the number of defects found within each module, you can calculate the total number of defects. Reviewing the number of defects found in each module can also help identify components that might require additional review or corrections. If you or your company possesses only one module, the total number of defects would solely be the defects found within that one module. When calculating defect density, it's first important to identify the number of defects within each module of your code. Here are some steps you can follow to calculate your programs' or software's defect density: 1. Software Engineer: What's the Difference? How do you calculate defect density? A higher defect density, conversely, might suggest that a company may want to refine its software before advertising and selling its software to consumers. While the standard for defect density may differ between companies and industries, a lower defect density can indicate that a product might be ready for customer markets.

Defect density can also help companies identify improvement opportunities within their software development teams and processes. This metric helps companies analyze the performance of their products, software and modules. What is defect density?ĭefect density is the number of defects found within a software's lines of code. In this article, we explain what defect density is, how it benefits companies and how to calculate the defect density of a module or program with an example. These companies often incorporate performance metrics such as defect density to identify areas that could be improved and help your company determine whether a program is ready for consumer markets. Technology and software development companies rely on developing quality programs for customers to generate revenue and profits.
