Open Systems Architecture

Open Systems Architecture (OSA) refers to a design approach for building complex systems with standardized, modular components that can easily connect and communicate. This openness allows different manufacturers’ parts and software to work together seamlessly, fostering flexibility, interoperability, and easier upgrades. Think of it like building with LEGO blocks—each piece can be replaced or added without redesigning the whole system. OSA is common in fields like software, military equipment, and industrial systems, enabling organizations to adapt, innovate, and reduce costs by using widely available components and standards.
