Visualize the flow of information with a data flow diagram

Within any digital process or system, information must move in more than one direction. This may be a simple back-and-forth (like filling out an online quiz), or a more complicated process involving several data entry points, like buying merchandise through a third-party seller.

In any case, those who want to improve or build such systems must keep track of what information is needed, where that information comes from, and where it needs to go. If you need to map out a system in this way, one simple yet effective method is to use a data flow diagram.

Data flow diagrams use simple symbols and notes to map how the data moves in a particular system. System designers can use these diagrams to create new systems or to catch any discrepancies or bottlenecks in existing systems. Maintaining a clear picture of where the data flows can save money, increase efficiency, and improve user experience.

Lucidchart offers a simple, customizable data flow diagram that you can use as a resource for your entire team. It can be updated with existing data in real time and accessed anytime and anywhere, which makes it ideal for remote teams.
