Abstract
The traditional development lifecycle using existing methods of system engineering result in
• Assurance-related post-unit test software rework at 50% of total system cost and growing
• Labor-intensive system safety analysis without addressing software as major hazard source
• High percentage of operator work arounds for software fixes due to high recertification cost
