Organizations can use application data flow diagrams to understand, perfect, and implement new processes or systems simply and efficiently. Because they are visual representations of your process or system, they are simple to understand and prune. An application data flow diagram allows you to understand better the operation of a procedure or system to identify potential problems, improve efficiency, and develop better processes. They can range from simple overviews to complex, granular representations of a process or system. DFDs can help almost anyone understand a system's logic and functions by visually displaying how it works. Because visualizing how a process or system works can hold people's attention and explain complex concepts better than blocks of text, they can help almost anyone grasp the logic and functions of a system or process.
