Designing safe products and systems is critical to reduce accident risk and minimize product liability. There are various reliability and quality analysis methodologies used to ensure safety including risk analysis techniques such as fault tree analysis (FTA), failure mode and effects analysis (FMEA), and others. This webinar focuses on providing an introductory look at FTA and its role in promoting safety. We review basics about fault tree analysis, including what it is, its history, its uses and advantages. A thorough review of qualitative and quantitative FTA results, including minimal cut sets (MCS), quantitative metrics such as unavailability, and importance measures, is included. The presentation concludes with guidance on how FTA qualitative and quantitative results can be used to design inherently safer products and systems.
