Product-based Quality
Product-based quality is a quality perspective that defines quality according to measurable product characteristics and attributes.
“A view of quality measured by the degree that well-defined quality characteristics are met.”

View the complete ISTQB GlossaryWhat is Product-based Quality?
From this viewpoint, higher quality is achieved when the product possesses desirable characteristics such as reliability, maintainability, and performance.
Attribute focused: Quality is measured through product characteristics.
Objective evaluation: Relies on measurable criteria.
Comparison: Products can be evaluated using standardized metrics.
Real World Example
A regulated product team is preparing a release where Product-based quality appears in reviews, test design conversations, or defect triage rather than as an isolated glossary word.
The risk is that the team treats Product-based quality 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 Product-based quality and similar ideas.
The page becomes useful in practice because Product-based quality is connected to a specific testing decision, not memorized as a detached definition.
