Creating black boxes in DFDs helps analysts focus on what aspect of the system?

Creating black boxes in Data Flow Diagrams (DFDs) emphasizes the analysis of the functions performed and the outputs produced by those functions within a system. By using black boxes, analysts can concentrate on understanding how data moves through the system without getting bogged down by the internal workings or the implementation details. This approach allows for a clearer representation of the system's behavior, highlighting how inputs are transformed into outputs through various processes.

The use of black boxes is particularly beneficial for identifying how different components interact and how data flows between different stages in a system, facilitating a more effective examination of system requirements. By abstracting away the complexities, analysts can maintain a high-level overview, enabling better communication and understanding among stakeholders, which is crucial in the early stages of systems analysis and design.
