== Best practice approach ==
Based on our experience we’ve found that escalation factors work best when they’re used to identify and highlight a limited number of real problems or weaknesses in the organisation. This approach leads to BowTies which do not exhaustively describe all the potential ways in which barriers can fail, but instead highlight key areas that need extra attention. Sometimes less is more, and this is certainly true for escalation factors. Use escalation factors as exclamation marks instead of exhaustive lists, and the communicative value of the BowTie will be increased tremendously.
