Software safety is a crucial aspect during the development of modern safety-critical systems. However, safety is a system level property, and therefore, must be considered at the system-level to ensure the whole system’s safety. In the software development process, formal verification and functional testing are complementary approaches which are used to verify the functional correctness of software; however, even perfectly reliable software could lead to an accident. The correctness of software cannot ensure the safe operation of safety-critical software systems. Therefore, developing safety-critical software requires a more systematic software and safety engineering process that enables the software and safety engineers to recognize the potential software risks. For this purpose, this dissertation introduces a comprehensive safety engineering approach based on STPA for Software-Intensive Systems, called STPA SwISs, which provides seamless STPA safety analysis and software safety verification activities to allow the software and safety engineers to work together during the software development for safety-critical systems and help them to recognize the associated software risks at the system level.

A new approach to safety, based on systems thinking, that is more effective, less costly, and easier to use than current techniques. Engineering has experienced a technological revolution, but the basic engineering techniques applied in safety and reliability engineering, created in a simpler, analog world, have changed very little over the years. In this groundbreaking book, Nancy Leveson proposes a new approach to safety—more suited to today's complex, sociotechnical, software-intensive world—based on modern systems thinking and systems theory. Revisiting and updating ideas pioneered by 1950s aerospace engineers in their System Safety concept, and testing her new model extensively on real-world examples, Leveson has created a new approach to safety that is more effective, less expensive, and easier to use than current techniques. Arguing that traditional models of causality are inadequate, Leveson presents a new, extended model of causation (Systems-Theoretic Accident Model and Processes, or STAMP), then shows how the new model can be used to create techniques for system safety engineering, including accident analysis, hazard analysis, system design, safety in operations, and management of safety-critical systems. She applies the new techniques to real-world events including the friendly-fire loss of a U.S. Blackhawk helicopter in the first Gulf War; the Vioxx recall; the U.S. Navy SUBSAFE program; and the bacterial contamination of a public water supply in a Canadian town. Leveson's approach is relevant even beyond safety engineering, offering techniques for “reengineering” any large sociotechnical system to improve safety and manage risk.

Safety and Reliability of Software Based Systems contains papers, presented at the twelfth annual workshop organised by the Centre for Software Reliability. Contributions come from different industries in many countries, and provide discussion and cross-fertilisation of ideas relevant to systems whose safety and/or reliability are of paramount concern. This book discusses safety cases and their varying roles in different industries; using measurement to improve reliability and safety of software-based systems; latest developments in managing, developing and assessing software intensive systems where reliability and/or safety are important considerations; and practical experiences of others in industry.
