Many other instructional design models, and even ISPI’s Human Performance Technology model, can be aligned with the steps of the ADDIE framework. There is also some debate in the field as to whether ADDIE is its own instructional design model. It would be most appropriate to call it a framework instead of a model because a model will prescribe detailed steps of a process, and ADDIE is rarely defined well enough to be considered a full instructional design model.
