The document discusses barrier-based risk management and BowTie analysis. It explains that BowTie analysis can be used to answer three questions: 1) Do we understand what can go wrong? 2) Do we know what our systems are to prevent this from happening? 3) Do we have information to assure that the systems are working effectively? The document provides examples of how organizations like the CAA UK and SIGTTO have used BowTie analysis to identify and manage significant risks in their industries.
