The ADDIE Model is a step by step guide for creating learning experiences. It has five phases: Analyze (understand the learning needs), Design (plan what to teach), Develop (create the materials), Implement (deliver the lesson), and Evaluate (check how well it worked). Each phase can be repeated to improve the learning program. ADDIE helps designers create effective lessons and training, whether in a classroom, online, or in a company setting. (Branch, 2009)
