It can be used to describe something that has a stable and unchanging arrangement or organization, often in contexts like architecture, systems, or frameworks.
Example: "The building was designed with a fixed structure to ensure its stability during earthquakes."
Alternatives: "a stable framework" or "an unchanging arrangement".
