Instructional Systems Design (ISD)

The ADDIE model is a systematic instructional design model consisting of five phases: (1) Analysis, (2) Design, (3) Development, (4) Implementation, and (5) Evaluation. Various flavors and versions of the ADDIE model exist using a vertical approach. This provides greater flexibility within the model compared to its original linear form.
