Difference between use case and test case

Defect management process is important in software development teams because developers will be able to determine the importance or the impact of the defect. The process also can prevent defects; implementation of test techniques, methodology and standard processes to reduce the risk of defects. By following the defect management process, the software developers are able to categorize/prioritize the defect if this needs fixing straight away or this can wait until the next releases. This also can improve the development process as this can prevent the defects from occurring again.
