Agile Business Analysis Practice

Data flow diagrams are used to illustrate how what moves through a system?

1. Users

2. Assets

3. Information

4. Processes

The correct answer is: Information

Data flow diagrams (DFDs) are designed to visually represent the movement of information within a system. They focus on the flow of data between processes, data stores, and external entities, helping stakeholders understand how data gets processed, stored, and transferred through various components. The primary function of DFDs is to map out how information is transformed as it moves from one part of a system to another. This visual representation is crucial in identifying any inefficiencies or potential improvements in how data is handled. By illustrating the flow of information, DFDs provide clarity on interactions and dependencies within a system, which is essential for effective business analysis in an Agile environment. While users, assets, and processes are all important elements of a system, the emphasis of a data flow diagram is specifically on the information and how it flows through different components or processes. This information-centric focus distinguishes DFDs from other types of diagrams that might emphasize broader concepts like user roles or system architecture.
