Your question is Prioritize Tests Using Risk-Based Testing. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
You are planning QA for a release and cannot run every possible test before sign-off. Some areas of the product are business-critical, some change frequently, and some have a history of defects, so you need a clear way to focus limited testing effort where failure would matter most.
How do you prioritize test cases using risk-based testing?
