@kurtseifried @joshbressers you don't know or more precisely, you gather qualitative information from retrospective and incidents that tells you. There is a whole field of practice and research about it, happy to introduce some readings.
And yes. Every action is contextual and need to constantly change! Exactly! Safety and security is something you constantly do. You replan and you look for the context to change.
@kurtseifried @joshbressers i also have practices and research to share about that if you are interested. The same. This is a relatively well explored domain in the safety world, if a bit... Out of view.
