Architectural flexibility refers to the ability of a system to adapt to changing requirements, such as modifications to the system model or updates to the system's technology or environment. When a system is designed with architectural flexibility in mind, it supports the concept of system separation of concerns by enabling different components to be modified or updated independently without affecting the integrity of the system as a whole.
For instance, a modular architecture might include separate modules for user input, data processing and output. By isolating each of these concerns into separate modules, the system can be easily modified, updated or replaced without affecting other parts of the system. This approach also allows developers to work on individual concerns in isolation, resulting in faster development times and more efficient use of resources.
Overall, architectural flexibility is critical for supporting system separation of concerns because it enables effective management of complexity, reducing the risk of errors or defects and allowing for better scalability of systems.
