To understand the ADDIE model, we have to go back to the 1970s. The U.S. military needed a consistent and effective way to train its personnel on a massive scale. How do you make sure every soldier, sailor, and airman learns the same material to the same standard, no matter who the instructor is? You need a system.

In response to this challenge, the Center for Educational Technology at Florida State University developed a model that would become the foundation for ADDIE. This work was part of a larger field called Instructional Systems Development, or ISD.

ISD provides a structured process for the entire training lifecycle, from figuring out what needs to be taught all the way to delivering and evaluating the instruction. The model developed at FSU was a specific, repeatable recipe within this broader ISD cookbook.

Initially, the model was strictly linear. It was a one-way street where you had to complete each step before moving to the next. There was no jumping ahead or circling back. The process looked like a straightforward assembly line for creating training.

Each phase had a clear purpose:

• Analysis: Figure out who needs training and what they need to learn.
• Design: Outline the learning objectives, course structure, and content.
• Development: Create the actual course materials, like manuals and lesson plans.
• Implementation: Deliver the training to the learners.
• Evaluation: Check if the training worked as intended.

This rigid, step-by-step approach provided the structure and discipline the military required. It ensured that nothing was missed and that the final product was comprehensive and well-planned.

Time to review the origins of this foundational model.

This systematic foundation, born out of a practical need, is why ADDIE has remained a cornerstone of instructional design for decades.
