A business analyst is tasked with implementing a new feature in an existing software product. The analyst needs to understand how the new feature will integrate with current system functionalities and data flows. To visually represent the interactions between the new feature (as a process) and external entities (users, other systems), which modeling technique would be most appropriate?
- AData flow diagram (DFD)
- BOrganizational chart
- CGantt chart
- DWork breakdown structure (WBS)
Show answer & explanationAnswer & explanation
Correct answer: A. Data flow diagram (DFD)
A Data Flow Diagram (DFD) is specifically designed to visually represent the flow of data through a system or process, showing how data enters, is processed, stored, and exits, as well as interactions with external entities.
Why the other options are wrong
- B. An organizational chart illustrates reporting relationships within an organization.
- C. A Gantt chart is a project management tool for scheduling tasks over time.
- D. A Work Breakdown Structure (WBS) decomposes project deliverables into smaller, manageable components.
Data Flow Diagram (DFD)
A graphical representation of the flow of data through an information system, showing how data is input, processed, stored, and output.
- Uses symbols for processes, data stores, external entities, and data flows.
- Helps understand system boundaries and interactions.
- Can be leveled to show increasing detail (Context, Level 0, Level 1, etc.).
Memory trick: Model the FLOW of data to know how it goes.
