Many organizations struggle with the level of detail when defining barriers. For example: should barriers be fully independent and therefore be more generically defined? Or does that make the barriers less useful, because fewer details are presented and assessed?

Often organizations need more than just one level of detail. It all depends on your goal. For example: quantification of the bowtie diagram can only be done with independent, high level barriers. Communication of safety critical tasks (SCTs) can only be done when showing specific detailed barriers, including detailed responsibilities, etc.

Example: 'Evacuation plan'

Barrier families allow you to toggle between multiple levels of specificity and grouping. With a single click, you can open the barrier family and show the family members.
