Internationalization
Internationalization is the process of designing software so it can be adapted to different languages, regions, and cultures without changing the source code.
“The process of making a system suitable for international user groups.”

View the complete ISTQB GlossaryWhat is Internationalization?
Internationalization prepares software for localization by separating language-dependent content and supporting regional formats.
Language independence: Text and resources are externalized from the application.
Regional support: Dates, currencies, and formats adapt to local settings.
Testing focus: Verify software behaves correctly across supported locales.
Real World Example
A regulated product team is preparing a release where Internationalization appears in reviews, test design conversations, or defect triage rather than as an isolated glossary word.
The risk is that the team treats Internationalization 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 Internationalization and similar ideas.
The page becomes useful in practice because Internationalization is connected to a specific testing decision, not memorized as a detached definition.
