When working with a Cross Functional diagram in Visio 2010 you may find yourself zooming in and out to remember which lane you are in. Another issue is printing out large CFF diagrams across multiple pages.
If you are working near the lane headings it is easy to know which lane you are in.
But zoom in to the other side of the diagram…
now which lane are you in, or which lane does this process shape belong to.
Quick Tip: Use custom fill patterns to make your own watermarks that help you easily identify the lanes at any zoom level and on any printed version of your diagram.
