V&V Goals: Why V&V?
1. Quality products
2. Problem prevention, detection, and resolution as early in the lifecycle as possible
Build an effective system efficiently

V&V Overview
V&V Concepts: How to do V&V
• Focus on key work products• Verify and validate against
reliable criteria– Standards– Requirements– Templates– Previously V&Ved work products
• V&V is used as a basis for key decisions
Perform V&V Early and Incrementally

V&V Overview
Doing V&V: What should V&V do
Verification- Ensures that selected work products meet their specified requirements
Validation- Demonstrates whether a product or product component will fulfill its specified purpose when placed in its intended environment
V&V is broader than T&E.The performance of T&E supports the goals of V&V.

V&V Overview
Status of V&V in the FAA
• V&V policy and guidelines in place– Still needs to be put into practice– V&V Guidelines updates and tools needed
• Test standards established and evolving– Updating T&E policy and processes to address NextGen needs– Test Standards Board providing technical, standards, and process
support
• V&V capabilities needed for NextGen– New V&V methods and lab capabilities– Focus on system-of-systems simulation and modeling
