A charter-driven, time-boxed template for exploratory testing: 5 minutes to charter, 35 to test, 10 to debrief — and notes someone can read.
Two days of regression, signed off green, and a regression shipped in the most-used feature. The tests weren't wrong — they were testing a stale picture.
A 30-second readiness check before accepting a ticket into QA — testable criteria, defined edge cases, reachable build, known data — that replaces a day of back-and-forth.
Three different tools on a spectrum from prescribed to open: when to write a scripted case, a coverage scenario, or an exploratory charter.
The working log that isn't a bug report or a test case — coverage, open questions, un-reproducible anomalies, painful setup — that makes a tester faster and more credible.
