Behavior-Driven Development (BDD)

Core Philosophy

BDD bridges business and technical teams through:

• Concrete examples that describe system behavior
• Ubiquitous language shared by all stakeholders
• Living documentation that serves as executable tests

Discovery → Development → Delivery

1. Discovery: Collaborate to understand requirements (Three Amigos, Example Mapping)
2. Development: Implement guided by examples (outside-in)
3. Delivery: Validate against real behavior

Writing Workflow

1. Clarification First
