The ADDIE model is a 5-phase instructional design model used for developing training programs: (1) Analysis, (2) Design, (3) Development, (4) Implementation, (5) Evaluation. The Analysis phase identifies learning needs and goals. The Design phase develops learning objectives and assessments. The Development phase creates instructional materials. The Implementation phase delivers the training. The Evaluation phase provides formative feedback and summative assessment of the training program. The ADDIE model provides a systematic process for designing effective training to meet identified learning needs.
