Informal reviews encourage quick feedback and early defect detection without the overhead of structured review techniques.
Flexible approach: Participants choose their own review method.
Fast feedback: Suitable for early work products and small changes.
Low overhead: Minimal preparation and documentation are required.
Real World Example
A regulated product team is preparing a release where Informal review appears in reviews, test design conversations, or defect triage rather than as an isolated glossary word.
The risk is that the team treats Informal review as interchangeable with nearby ISTQB terms. That makes test scope blurry and can lead to weak evidence for the release decision.
The tester anchors the discussion in the official definition, asks where the concept appears in the product, and designs examples that show the difference between Informal review and similar ideas.
The page becomes useful in practice because Informal review is connected to a specific testing decision, not memorized as a detached definition.
