Storyboarding a Project
In a large project you may want to consider multiple storyboard documents to keep things organized. Perhaps one just for the audio narration script, one for a video that will be used in the course, or maybe one for asset management of all the images. Here's a list of a few that could be used:
instructional design with a script
instructional design without a script
audio script only
video shot list
assessments
interaction design
Remember, the "art" of storyboarding does not adhere to any steadfast rules. Depending on what your project entails, add or design storyboard documents that fit the need.
Another idea may be to add a Storyboard Workbook to your project plan. The workbook would include all the documents used for the design and development of the course including the visual storyboard, style guides with colors and fonts, and an asset library listing all the images and graphics. With the above potential storyboard documents and these listed here, even a small project would benefit from having these resources.
Your style is yours, and remember there are no rules to storyboarding—only benefits.
