System Safety: Seven Foes of Intervention

In this short series, I highlight seven foes and seven friends of system safety, both for explanation and intervention. Each is a concept, meme, or device used in thinking, language, and intervention (reinforced by more fundamental foes that act as barriers to thinking).  They are not the only foes or friends, of course, but they are significant ones that either crop up regularly in discussions and writings about safety, or else – in the case of friends – should do.

In this post, I outline seven foes of intervention.

Never/Zero Thinking

There has been much talk in recent years about ‘never events’ and ‘zero harm’, similar to talk in the safety community about ‘zero accidents’. It sounds obvious: no one would want an accident. And we all wish that serious harm would not result from accidents. But as expressed and implemented top-down, never/zero is problematic for many reasons. In this post, I shall outline just a few, as I see them.
