The article discusses how predicting software reliability can make safety-critical software, like the NASA Space Shuttle's, more trustworthy. The authors developed a new method that combines safety criteria, risk analysis, reliability prediction, and testing rules to enhance software safety. They focus solely on software safety, not hardware or human errors. By improving software reliability, they help ensure mission and crew safety. Software reliability models are essential tools for software managers to meet safety goals, along with inspections, reviews, testing, and experience.
