Fishbone Diagram - Ishikawa Diagram, Cause-and-Effect Diagram

A fishbone diagram visually represents a network's causal system analysis (sometimes known as a cause-and-effect diagram or an Ishikawa diagram).

As seen below, a NILS site displays a Fishbone menu item, which can be selected to access the fishbone diagram page. 

Note: Depending on your NIC’s NILS instance, phase, and your network role, some items may appear differently in the menu bar.
