ADDIE Model in Instructional Design Model

ADDIE Model

Summary: The ADDIE model is a systematic instructional design model consisting of five phases: (1) Analysis, (2) Design, (3) Development, (4) Implementation, and (5) Evaluation. Various flavors and versions of the ADDIE model exist.

ADDIE Model
The generic term for the five-phase instructional design model consisting of Analysis, Design, Development, Implementation, and Evaluation.  Each step has an outcome that feeds into the next step in the sequence.  There are probably over 100+ different variations of the generic ADDIE model.

The five phases of ADDIE are as follows:
Analysis
During analysis, the designer identifies the learning problem, the goals and objectives, the audience’s needs, existing knowledge, and any other relevant characteristics.  Analysis also considers the learning environment, any constraints, the delivery options, and the timeline for the project.
Design
A systematic process of specifying learning objectives.  Detailed storyboards and prototypes are often made, and the look and feel, graphic design, user-interface and content is determined here.
Development
The actual creation (production) of the content and learning materials based on the Design phase.
Implementation
During implementation, the plan is put into action and a procedure for training the learner and teacher is developed.  Materials are delivered or distributed to the student group. After delivery, the effectiveness of the training materials is evaluated.
Evaluation
This phase consists of (1) formative and (2) summative evaluation. Formative evaluation is present in each stage of the ADDIE process. Summative evaluation consists of tests designed for criterion-related referenced items and providing opportunities for feedback from the users.

Revisions are made as necessary.
Rapid prototyping (continual feedback) has sometimes been cited as as a way to improve the generic ADDIE model.
