I have used the "Quality Alerts" with good results, sometimes a picture is the best way to convey the information. Of course I make it controlled, usually filed with the WI number reference. Lately I have been making "Visual Procedure Manuals", which are essentially WI's with accompanying illustrations. The customers like them also. I make two (controlled) copies generally, one for the shop floor, and one to keep for reference in the QA lab. As changes are made during production, they are modified and revised. The old one is removed from the shop floor and reprinted with the new rev number, the QA copy is kept as is but the new material added to the back. That way I have a record of the changes that were made. When the job is over, they get marked 'obsolete' and filed with any production records. One disadvantage (?) it generally requires that the person putting it together is very familiar with the entire process, so every detail can be documented. As a result, I can now build many items we make by myself ! But that is what a good manual should enable someone to do.
