Data Flow Diagrams: A Visual Representation of Information Flow
Let me tell you why I love Data Flow Diagrams so much!!
Hello fellow BAs, and Welcome Back for another technique in the series Business Analysis Techniques.
What are Data Flow Diagrams (DFDs)?
So Why I love Data Flow Diagrams? Because DFDs are awesome, that’s why!
They allow us to visualize and analyse the data flow within a system. They help us to understand how information moves from one process to another, what inputs and outputs are involved, and where data is stored or exchanged. They also help us to communicate with stakeholders by providing a common visual language that everyone can understand.
DFDs are especially useful for transaction-based systems, where data is constantly being processed and shared between different components.
For example, think of an online shopping system, where customers place orders, products are shipped, payments are processed, and inventory is updated. A DFD can show how all these processes interact with each other and with external entities like customers, suppliers, banks, etc.
