Measurement, Metrics, and Magic Numbers
- Bugs that could have been found in requirements gathering cost 1000 times more when found in production.
- Testing costs 40% of the total development effort.
- When the fix rate trendline crosses the failure rate trendline, it’s time to release the product.
- The ROI of testing can be calculated by a straightforward formula.
- Risk = Probability x Impact
- Defect Removal Efficiency is a good way to evaluate the quality of testing.
- You can’t manage what you can’t measure.
If you’re a tester or test manager, you’ve probably seen someone pull numbers out of a hat. As part of the trick, skepticism often vanishes into thin air.
Numbers can have magical powers. In the right hands, numbers can reveal remarkable things that might otherwise be invisible. Yet numbers may also have enormous power to dazzle, distract, and deceive. How do you know that what you seem to be seeing is real, and not just an illusion?
Critical Thinking Skills for Testers
Tutorial at the 2023 EuroSTAR Software Testing Conference
13:30-17:00 CEST Tuesday 13th June
Critical thinking isn’t just “good thinking”. It’s the kind of thinking that specifically looks for problems and mistakes. Regular people don’t do a lot of that, but to be a great tester, you need to be a great critical thinker. Critically-thinking testers help to save projects from dangerous assumptions and hidden problems, and ultimately from disasters.
The good news is that critical thinking is not just innate intelligence or a talent—it’s a learnable and improvable skill you can master. Critical thinking begins with five questions—Huh? Ready? Really? And? So?—that kick-start your brain. Those questions prepare you to analyse specifications, risks, causes, effects, project plans, and anything else that could puzzle, confound, or fool you, your colleagues, or your clients.
