I want to create a bow tie diagram without having to start completely from
scratch or purchasing additional software. I am hoping a template exists
somewhere. Bow tie diagrams are risk assessment flow diagrams that are
shaped like a bow tie with the Hazards and associated preventative controls
on the left hand side flowing to a centre "undesirable event" and then
flowing out to a significant consequence. Along the lines feeding into and
out of the centre are boxes that represent controls or barriers that either
prevent the undesirable event (left side) or the consequence right side.
Anyone who has seen or used one will know what I mean.
