This document compares two common models of instructional design: the ADDIE model and the Dick and Carey model. The ADDIE model consists of five sequential phases - Analyze, Design, Develop, Implement, and Evaluate. It is widely used but can limit creativity. The Dick and Carey model is also called the Systems Approach Model. It is a 10-step process used often in education that includes ongoing formative and summative evaluations. Both models are systematic in their approach and focus on inputs, outputs, and the design process, but the Dick and Carey model has more steps and allows for incremental improvements.
