Maturity
Maturity is the degree to which an organization's processes are defined, managed, measured, and continuously improved.
“(1) The capability of an organization with respect to the effectiveness and efficiency of its processes and work practices. (2) The degree to which a component or system meets needs for reliability under normal operation.”

Process maturity reflects how consistently an organization performs its activities and how effectively it can deliver predictable, high-quality results.
Process definition: Mature organizations use standardized processes.
Continuous improvement: Processes evolve through measurement and feedback.
Testing impact: Mature testing processes improve product quality and predictability.
Real World Example
A regulated product team is preparing a release where Maturity appears in reviews, test design conversations, or defect triage rather than as an isolated glossary word.
The risk is that the team treats Maturity 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 Maturity and similar ideas.
The page becomes useful in practice because Maturity is connected to a specific testing decision, not memorized as a detached definition.
