What problem does it solve? Requirements defects discovered late in development cost 10-100x more to fix than those caught during validation. This Skill guides the formal validation step of the Requirements Management cycle, ensuring specifications are both internally correct (verification) and actually solve stakeholder needs (validation) before sign-off. ## Core Features & Use Cases - Verification vs Validation Distinction: Separates quality-standard checks (IEEE 830 checklist) from stakeholder need confirmation, preventing approval of well-written but wrong requirements. - Multiple Validation Techniques: Supports informal walkthroughs, formal Fagan inspections with defect taxonomy (Missing/Wrong/Extra/Ambiguous/Inconsistent), prototype validation, and UAT sessions. - Sign-off Matrix & Flow Decision: Produces a formal approval matrix per stakeholder and a documented decision to advance to requirements management or return to analysis with specific defects. - Use Case: After completing a requirements specification baseline, run this Skill to inspect 40 checklist items per requirement type, log defects by severity, hold a stakeholder review session, and produce a signed validation report. ## Quick Start Ask the AI to validate the requirements specification in your work package and produce a validation report with defect log and stakeholder sign-off matrix.
