Critical System Assurance Challenge


Software Engineering Institute


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
