A level 1 data flow diagram (DFD) is more detailed than a level 0 DFD but not as detailed as a level 2 DFD. It breaks down the main processes into subprocesses that can then be analyzed and improved on a more intimate level. You can edit this DFD level 1 template with a free Lucidchart account. After signing up, you can change the shape placement, text content, and more.
