The ADDIE Process The ADDIE instructional design model forms a roadmap for the entire training project. Intulogy uses this popular instructional design model to help our clients analyze their training needs, design and develop training materials, implement training, and evaluate its effectiveness. Sometimes, Intulogy works directly with a client's training specialists, who have studied the ADDIE model in graduate school. However, we're often contacted by directors and executives who know their company has a training need, but they don't know much about the instructional design process.
