Peter FeilerAircraft and other safety-critical systems increasingly rely on software to provide their functionality. The exponential growth of software in safety-critical systems has pushed the cost for building aircraft to the limit of affordability. Given this increase, the current practice of build-then-test is no longer feasible. This blog posting describes recent work at the SEI to improve the quality of software-reliant systems through an approach known as the Reliability Validation and Improvement Framework that will lead to early defect discovery and incremental end-to-end validation.
