ADDIEModell

ADDIEModell, commonly referred to as the ADDIE model, is a foundational framework in instructional design used to plan, develop, deliver, and evaluate educational and training programs. It advocates a systematic sequence of five phases that teams can tailor to their context: Analysis, Design, Development, Implementation, and Evaluation. In Analysis, designers assess learning needs, learner characteristics, context, and performance gaps. In Design, learning objectives, assessment methods, instructional strategies, and sequencing are defined. In Development, instructional materials, media, and activities are created and assembled. In Implementation, the program is delivered to learners and conditions for learning are established. In Evaluation, data on learning outcomes and process effectiveness are gathered to inform revisions and improve future iterations.

The model originated in the 1970s within U.S. military and government-related research at Florida State University and has since become widely adopted in education, corporate training, and e-learning.

ADDIE is valued for its clarity, documentation, and transferability, enabling project management and scalable development. It is commonly presented as linear, but practitioners frequently apply iterative loops between phases to respond to feedback and changing requirements.

Critics note that rigid adherence can slow development and that ADDIE does not prescribe instructional methods; it is mainly a planning and evaluation framework. Variants such as SAM (Successive Approximation Model) or agile adaptations aim to speed up cycles while preserving its core structure.
