# Loose Coupling **Loose coupling** in SDVs ensures modularity by **decoupling software from hardware dependencies**, enabling faster updates and scalability. An **API-first approach** allows components to communicate via well-defined interfaces, reducing direct dependencies and enabling parallel development. **Freeze points** define stable integration layers, ensuring that while internal components evolve independently, system-wide compatibility is maintained. This balance between flexibility and stability accelerates innovation while preserving reliability in software-defined architectures. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://www.sdv.guide/pulse/loose-coupling.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
