New Fisher Grid
One of the things we use at Newsplex, and that I use in some of my classes, is a one-page sheet that started out being called by the ungainly "story organization and planning," but was rechristened the "Fisher Grid" by my co-authors of "Principles of Convergent Journalism."
It provides a structured way to think about planning a story across media, including thinking about the best way to tell the story and then backing down to alternatives based on the resources you have.
With new options and the rise of easy-to-do slideshows, etc, it needed an update. So a new version is available over at the PCJ wiki. It's a Word doc so you can fill it in by hand or put it up on a computer and fill it in that way, as my students do.
