##  [ADDIE Model](/addie-model-0) 

 Definition

An instructional systems design framework composed of five phases—Analysis, Design, Development, Implementation, Evaluation—used to organize and guide systematic creation, deployment, and assessment of instructional materials and programs.

 

 

 

 

 

 





## Principle

Principle

Decomposing instructional development into analysis, design, development, implementation and evaluation encourages alignment of needs, objectives, materials, delivery, and assessment and supports iterative improvement when evaluation informs earlier phases.

 

 

 

 

 





## Demonstration

Demonstration

Illustrative scenario — Situation: A company needs safety training. Recognition (Analysis): target tasks and learner gaps are identified. Action (Design/Development): learning objectives, media, and materials are created; Implementation: trainers deliver the course; Evaluation: learner performance and program metrics are measured and feedback is used to revise materials. Consequence: the cycle yields materials aligned to needs and subject to improvement based on evidence.

 

 

 

 

## Misapplication

Misapplication

Applying ADDIE as a strictly linear, one‑time waterfall (complete phases sequentially without feedback) and omitting iterative revision. The error is treating evaluation as an endpoint rather than as input for continuous improvement.

 

 

 

 

 





## Consequence

Consequence

When used iteratively, ADDIE promotes alignment, traceability, and evidence‑based refinement of instruction; when applied rigidly it can produce delayed responsiveness, wasted resources, or outmoded materials.

 

 

 

 

## Reversal

Reversal

In contexts requiring rapid, incremental delivery (e.g., short development cycles or emergent needs), lighter-weight or agile instructional design practices may replace or adapt ADDIE’s formalities while preserving its alignment goals.

 

 

 

 

 





## Boundary

Boundary

Clearly within: structured development of courses or training programs that benefits from staged analysis, design, development, implementation and evaluation. Boundary case: a single lesson created by one instructor without formal analysis. Clearly outside: improvised, ad hoc tutoring without systematic design.

 

 

 

 

 





## Semantic Tension

Semantic Tension

Structure/Rigor ↔ Agility/Speed — comprehensive, documented design supports quality and alignment but can conflict with the need for rapid iteration and quick deployment.

 

 

 

 

 





## Synthesis

Synthesis

ADDIE is a functional checklist and organizing logic for instructional development; its educational value depends on using evaluation feedback to iterate rather than treating phases as a rigid linear sequence.
