Event Modeling

Collaborative visual design technique created by Adam Dymitruk. The Event Model IS the specification -- it replaces traditional requirements documents with a single, living visual artifact.

Key Properties

• Collaborative: Everyone participates (devs, business, UX)
• Visual: Colored elements on a timeline (physical or digital board)
• Timeline-based: Events arranged chronologically, left to right
• Spec-generating: Model directly produces testable Given/When/Then specifications
• Technology-agnostic: Describes WHAT happens, not HOW it's implemented
