Storyboarding is an essential skill for any Instructional Designer

What purpose does a storyboard serve in the training development paradigm? It is a beginning step in the development by providing a sense of rigor as part of the project planning and a method of conveying to the client what is planned, long before the content creation begins. The storyboard should define the goals and learning objectives, discuss the design and its elements, cover navigation and narration, and consider the assessments planned for the project, and much more.
