It is most useful when:

Set up properly.

Before you start, be clear on which heuristicsglossary×HeuristicA heuristic is a general rule or principle used to guide decision making.Open glossary term→ you will use, what parts of the product you are reviewing, and how issues will be recorded.

Use a consistent frameworkglossary×FrameworkA framework is a structured set of tools and conventions used to build applications more efficiently.Open glossary term→ to ensure coverage.
