The three questions every QA engineer should ask themselves

Good QA doesn’t start with tools or frameworks. It starts with three simple questions you should constantly ask yourself as a QA engineer.

1. What can go wrong?

Think like a user who wants to break the system — not a developer who wants to prove it works.

2. How quickly do we find out?

Fast feedback is more valuable than perfect coverage. The sooner you find a problem, the cheaper it is to fix.

3. Who is affected?

Not all bugs are equal. Prioritise by impact on the end user.
