I is for Implement
In face-to-face course development, the implement phase of ADDIE is the phase where the course is actually being taught. It is the phase where we take all the materials we have developed and use the strategy we designed to actually teach the course.
Where implement gets confusing is that it is a term that is used within software development as being synonyous for development. With the design and development of eLearning and multimedia projects, there isn't a clear line between develop and implement. I created the following video to describe one way in which ADDIE can be used when creating multimedia projects.
