Quality Assurance

Overview

This skill implements the Verification (VER) and Validation (VAL) process areas from the CMMI-based SDLC prescription.

Core principle: Verification ≠ Validation. Tests prove you built it correctly (VER). Users prove you built the right thing (VAL). Both required at Level 3.

Critical distinction:

• Verification: "Did we build the product right?" (tests, reviews, inspections)
• Validation: "Did we build the right product?" (user acceptance, stakeholder approval)
