Storyboarding as a Tool
A good analogy is to think of a storyboard as the blueprint for a house. Imagine you're a contractor building a new house and you have the best carpenter, bricklayer, roofer, and painters. You've chosen the location and have a general idea of how you want the house to look. You start by building the foundation, then begin putting up walls, adding a roof, and finishing all the details. By then you've realized you have an exterior door on the second floor that leads nowhere, a sink installed in a bedroom, and a fireplace with no chimney. How did this happen? By starting without a blueprint.
Now, apply this analogy to an eLearning project: You have great content, graphic artists, and developers, yet no storyboard. You're off and running building an award winning course only to learn there are dead ends, endless loops, or other poor design features. The storyboard is your blueprint. It has all the details and boundaries to keep things on a planned schedule.
