Beyond finding defects.
WHAT ACTUALLY IMPROVES QUALITY
Clearer requirements Better design Review before building Tests written alongside code Faster feedback Fewer defects introduced
WHAT DOES NOT
More testing at the end.
WHY
It detects rather than prevents, at the most expensive point.
WHAT TO ADVOCATE FOR
Testers involved in planning Acceptance criteria agreed before work starts Automated checks on every change Small changes, released frequently
WHY SMALL CHANGES MATTER
They are easier to review, test and reverse, and their failures are easier to locate.
WHAT TO MEASURE TO JUSTIFY CHANGES
Defects escaping Time from introduction to detection Time spent on regression
WHAT TO PROPOSE FIRST
Whatever addresses the most common escape cause.
HOW TO FIND THAT
Categorised defect causes.
WHAT TO AVOID
Process added without evidence it helps Documentation nobody reads Gates that delay without detecting
WHAT TO REVIEW PERIODICALLY
Whether each practice still earns its cost.
WHAT TO REMOVE
Practices that no longer do.
WHY THAT IS NECESSARY
Process accumulates, and nobody removes it without deliberate review.
