ADDIE Model

ADDIE is the dominant framework for instructional systems design, providing a structured process for developing training programmes. The acronym stands for Analysis, Design, Development, Implementation, and Evaluation.

Analysis: Identify the performance gap, define the target audience, determine constraints (time, budget, technology), and establish measurable learning objectives. Design: Create the blueprint — learning architecture, content sequencing, assessment strategy, and media selection. Development: Build the actual content — eLearning modules, videos, facilitator guides. Implementation: Deploy and run the programme. Evaluation: Measure effectiveness against the original objectives.

In practice, ADDIE is rarely a strict linear sequence. Modern ID practice often uses an iterative 'SAM' (Successive Approximation Model) approach — rapid prototyping and review cycles — particularly for eLearning development. However, the ADDIE phases remain the conceptual foundation.

Understanding ADDIE is essential for any L&D professional commissioning or managing training development. It defines the conversation about scope, timelines, and responsibilities between a training vendor and an L&D team.
