To have open communication while making few errors, have a culture where you can ask questions without judgement before doing stuff.

For example, it should be okay to ask “can I give Ibuprofen to pt. Y with diagnosis Z?” without thinking stuff like “will someone think I don’t know Ibuprofen, diagnosis Z or medicine?”

(from VG, who in turn took it from a lecture about Fehlerkultur in a semi-medical context)
