# 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.
