# SPARC Specification Phase (+1)

## SPARC Specification Phase


The Specification phase is the foundation of SPARC methodology:

1. **Define clear, measurable requirements** - Avoid ambiguity
2. **Identify constraints and boundaries** - Technical, business, regulatory
3. **Create acceptance criteria** - Testable pass/fail conditions
4. **Document edge cases and scenarios** - What happens when things go wrong
5. **Establish success metrics** - How to measure completion
