This episode is about the struggle to explain, measure, and name the work testers and quality advocates actually do — especially when traditional labels and metrics fall short.
Links to stuff we mentioned during the pod:
- 05:05 - Defect Detection Rate (DDR)
- The rate at which bugs are detected per test case (automated or manual)
- No. of defects found by test team / No. of Test Cases executed) *100
- 15:06 - David Evans' LinkedIn
- 24:57 - Janet Gregory
- 26:01 - Defect Prevention Rate
- Perplexity search results here
- 28:28 - Jerry Weinberg
- Jerry's Wikipedia page (his books are highly recommended)
- 49:33 - Shift-Left: The concept of moving testing activities earlier in the software development lifecycyle.
