An Instructional Design Document (IDD) allows you to catalog learning design architectural elements. The Instructional Design document is a guidebook for key individuals, such as stakeholders, subject matter experts, and peers who may be collaborating on your learning experience. By capturing these elements, you can provide key individuals with a snapshot or vision of the finished learning product. Knowledge of this information keeps all stakeholders heading toward the same goal. This documentation is also important when reviewing when a course should be retired (sunsetted), discontinued, or even resurrected.
