A third method for managing a highly complex Ishikawa diagram is to view the entire diagram as a collection of smaller diagrams. Any arrow (along with its sub-arrows) can be isolated into a separate diagram in a new window. This diagram can then be easily saved in a separate file.
To isolate a branch as a separate diagram, do the following:
-
Move the cursor over the head of the arrow.
-
Activate the popup menu using the right mouse button.
-
Select .
