Built-in Quality
Built-in quality is the practice of preventing defects by incorporating quality activities throughout software development rather than relying on testing alone.
“A set of practices to ensure that each solution meets quality standards throughout each increment of development, focusing on constructive quality assurance as a shared responsibility.”

Built-in quality emphasizes that every team member is responsible for quality. Practices such as code reviews, automated testing, continuous integration, and early feedback help prevent defects before they occur.
Prevention over detection: Quality is designed into the product from the beginning.
Shared responsibility: Developers, testers, and business representatives all contribute to quality.
Agile principle: Built-in quality is a fundamental concept in Agile and DevOps practices.
Real World Example
A regulated product team is preparing a release where Built-in quality appears in reviews, test design conversations, or defect triage rather than as an isolated glossary word.
The risk is that the team treats Built-in 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 Built-in quality and similar ideas.
The page becomes useful in practice because Built-in quality is connected to a specific testing decision, not memorized as a detached definition.
