ADDIE Model
Also known as ADDIE · نموذج ADDIE
Definition
ADDIE is a five-phase instructional design framework: Analysis, Design, Development, Implementation and Evaluation. Analysis establishes the need and audience, Design specifies objectives and assessment, Development produces the materials, Implementation delivers them, and Evaluation measures whether the intended change occurred and feeds the next cycle.
ADDIE is best understood as a checklist of concerns rather than a strict waterfall. Applied rigidly it delays any usable output until late in the project, which is why many teams now run it iteratively — prototyping a single module through all five phases before committing to a full program.
Its enduring value is that it makes omissions visible. Programs that skip Analysis solve the wrong problem; programs that treat Evaluation as an optional final step never learn whether they worked. Alternatives such as SAM prioritize rapid iteration, but they address the same five concerns in a different order.
