ADDIE Model

A-D-D-I-E is five phase systematic model used to create sound instructional products for a variety of educational settings. 

Each phase represents a series of tasks that help to ensure development efforts stay on track, on time, and on target.

• Analyze audience needs.
• Design a solution to meet those needs.
• Develop the solution.
• Implement the solution.
• Evaluate the effectiveness of the solution.

Completing each phase satisfactorily increases the chance that the information presented ultimately remains relevant to the needs of the audience.
