Episode 3: The ADDIE Model

A Systematic Framework for Instructional Design — Analysis, Design, Development, Implementation, Evaluation

3.1 What is ADDIE?

ADDIE Model - Analysis, Design, Development, Implementation, Evaluation
The ADDIE model: five phases of systematic instructional design

The ADDIE model is the most widely used framework for instructional design. Developed by Florida State University for the U.S. military in the 1970s, ADDIE provides a systematic, iterative process for creating effective learning experiences. The acronym stands for Analysis, Design, Development, Implementation, and Evaluation.

While often presented as a linear sequence, effective practitioners recognize that ADDIE is inherently iterative. Evaluation occurs throughout, and insights from later phases often lead back to earlier phases. The model is flexible enough to accommodate different contexts while providing structure that ensures quality and alignment.

"ADDIE is not a rigid prescription but a flexible framework. The best instructional designers use it as a guide, adapting the process to their context while maintaining its core principles." — Dr. Michael Allen, Allen Interactions

3.2 Phase 1: Analysis

Purpose: Understand the Problem and Context

The Analysis phase answers fundamental questions: What problem are we solving? Who are the learners? What do they need to know? What constraints exist? Skipping or rushing analysis is the most common cause of instructional design failure.

Key Activities

📋 Analysis Phase Checklist

  • ☐ Needs assessment completed and documented
  • ☐ Learner profiles created
  • ☐ Task analysis performed
  • ☐ Context and constraints identified
  • ☐ Stakeholders consulted and aligned
  • ☐ Project scope and goals defined

Common Analysis Methods

3.3 Phase 2: Design

Purpose: Create the Blueprint for Instruction

The Design phase translates analysis findings into a detailed plan for instruction. This is where learning objectives are written, content is structured, and instructional strategies are selected.

Key Activities

Design Documentation

The Design phase typically produces a Design Document or Instructional Design Plan that includes:

  • Project overview and goals
  • Learner profiles
  • Learning objectives (by module)
  • Content outline and structure
  • Assessment strategy
  • Instructional strategies and media
  • Timeline and resources needed

Design Tools

3.4 Phase 3: Development

Purpose: Build the Learning Materials

The Development phase transforms the design into tangible learning materials. This is where content is created, media is produced, and the learning experience is built.

Key Activities

📋 Development Phase Checklist

  • ☐ All content created according to design specifications
  • ☐ Media produced and integrated
  • ☐ Assessments developed and tested
  • ☐ Accessibility standards met (WCAG)
  • ☐ Functionality testing completed
  • ☐ SME review and approval obtained
  • ☐ Pilot testing conducted

Common Development Tools

3.5 Phase 4: Implementation

Purpose: Deliver Instruction to Learners

The Implementation phase is where learners experience the instruction. This includes preparing the learning environment, supporting facilitators, and managing the delivery process.

Key Activities

Implementation Considerations

Successful implementation requires attention to:

  • Communication: Clear instructions for learners about how to access and navigate the learning
  • Technical Readiness: Ensuring technology works reliably for all learners
  • Facilitator Preparation: Ensuring instructors understand the design and have necessary resources
  • Contingency Planning: Preparing for technical issues or other disruptions

3.6 Phase 5: Evaluation

Purpose: Assess Effectiveness and Improve

Evaluation occurs throughout ADDIE, not just at the end. Formative evaluation happens during design and development to catch issues early. Summative evaluation occurs after implementation to measure overall effectiveness.

Kirkpatrick's Four Levels of Evaluation

Formative vs. Summative Evaluation

"Evaluation is not the end of the process—it's the beginning of improvement. Every evaluation should lead to refinements that make the next iteration better." — Dr. Robert Brinkerhoff

3.7 ADDIE in Practice: Iteration and Flexibility

While ADDIE is often diagrammed as a linear flow, effective practice is iterative. Insights from Development may lead back to Design. Evaluation findings inform improvements that affect future iterations. The model is flexible enough to accommodate agile approaches while maintaining the discipline of systematic design.

Common ADDIE Variations

Rapid Prototyping: Creating early prototypes to gather feedback before full development

Agile ADDIE: Working in short sprints, delivering functional pieces iteratively

Continuous Improvement: Using evaluation data to refine materials over time

Lean ADDIE: Streamlining the process for smaller projects with limited resources

📌 Episode Summary

The ADDIE model provides a systematic framework for instructional design. Analysis defines the problem and context. Design creates the blueprint. Development builds the materials. Implementation delivers instruction. Evaluation measures effectiveness and guides improvement. Mastery of ADDIE—and knowing when to adapt it—is essential for effective instructional design practice.

In Episode 4, we'll explore alternative instructional design models including SAM (Successive Approximation Model), Agile ID, and the Dick and Carey Model.
