What is the ADDIE Model?

The ADDIE instructional design model is the standard process traditionally used by instructional designers to create learning content and experiences. The ADDIE model is at the very core of instructional design and is the basis of instructional systems design (ISD). The ADDIE Model is also known as the Instructional Systems Design (ISD) model. Most of the current instructional design models are spin-offs or variations of the ADDIE instructional design model. Below is a summary:

ADDIE Model Overview

The ADDIE Model was first created for the U.S. Military during the 1970s by Florida State University. ADDIE is an acronym for a five-phase course development process. The ADDIE model generally consists of five interrelated phases—Analysis, Design, Development, Implementation, and Evaluation. The ADDIE model represents a flexible guideline for building effective training and instructional materials. See each of the phases below:

In the analysis phase of the ADDIE model the instructional problem is identified. The instructional goals, success metrics, and overall objectives are also established. Information regarding the learner such as the learning environment, preferences, demographics, and existing knowledge and skills are also identified during this phase.


The design phase of the ADDIE model nails down learning objectives, instructional methods and activities, storyboards, content, subject matter knowledge, lesson outlines, and media assets.

The development phase of the ADDIE model is where instructional designers develop the content and learning interactions outlined in the design phase. During this phase, content is written and graphics, audio, and photography are also produced and assembled.

During the implementation part of the ADDIE model, the instructional designer delivers the content and materials to Learning Management Systems (LMS) or directly to the trainer for live training events. The instructional designer also provides training needed to trainers, facilitators, SME's or instructors. 

During the evaluation phase of the ADDIE model, the instructional designer  determines what success will look like and how it will be measured. Often times, the evaluation consists of two phases: formative and summative. Formative evaluation is iterative and is done throughout the design and development processes. This occurs all throughout the ADDIE process. Summative evaluation consists of tests that are done after the training materials are delivered. The results from these test help to inform the instructional designer and stake holders on whether or not the training accomplished its original goals outlined in the analysis phase.
