ADDIE Model

The ADDIE model is a generic instructional systems design process, its name an acronym for its five phases, Analysis, Design, Development, Implementation and Evaluation, that emerged from United States military and corporate training design work in the 1970s, notably a systems-approach training model developed at Florida State University's Center for Educational Technology for the U.S. Army in 1975, and became the dominant reference framework for how instructional designers plan a course or training program. In the analysis phase a designer identifies learners' needs and the gap between current and desired performance; in design, learning objectives and assessment strategies are specified; in development, the actual instructional materials are produced; in implementation, the training is delivered to learners; and in evaluation, both the learners' outcomes and the instructional materials themselves are assessed, often feeding revisions back into earlier phases. Although later instructional designers have criticized the model's classic linear presentation as too rigid for iterative, real-world design work and have proposed more cyclical variants, ADDIE remains the most widely taught foundational process model in instructional design and corporate training programs.
