This is a Visio template for a Context Level DFD (Data Flow Diagram). A Context Level DFD is often used in system analysis and IT projects to help determine scope. Typically, the name of the project or the system that is being worked on is put into the middle circle.
The boxes connecting to the middle circle are people, groups, departments, processes and other systems that will interact with your project. The connecting lines describe what input (information, business rules, etc) are being provided to you and what output you are providing to the other entities.
This Context Level DFD provides groupings of the connecting entities to help organize the document. This is useful anytime a group of entities share the same inputs or outputs.
It is important to complete the Context Level DFD early in the project. The connecting entities need to be aware and in agreement with the changes you are making since they will be impacted. The connecting entities are often considered stakeholders of your project.
The colors, green, yellow and red are used to demonstrate what connection points are in scope and out of scope for the given phase or duration of the project.
