Abstract Effective and efficient programmatic decisions are required throughout the design, development, and operation of the International Space Station (ISS), which involves sixteen countries, over one million pounds of flight hardware, and an on‐orbit assembly process spanning six years. Paramount to the success of the ISS, are the safety and mission assurance (S&MA) aspects of the program. Various S&MA products, such as critical items (CILs), safety nonconformances, and problem reports, all provide an individual assessment of the program's risk throughout the design, development, and operation phases of the ISS life cycle. However, until recently, no method existed for measuring the overall S&MA risk of NASA programs. The NASA International Space Station Program's Safety and Mission Assurance/Program Risk Office (S&MA/PR) has developed such a metric.
