Can you describe what a 'USE' case is and what elements it should include?

As a quality assurance engineer, you need to understand the software development process as well as the programmers and coders do. This will enable you to better identify the root causes of errors and bugs, especially if they recur frequently. This may extend to understanding individual programming languages and the techniques programmers use when developing applications. As with any profession, the better you understand the material you are working with, the more effective you will be at your job.
