The recent incident in the Delhi metro where the train travelled some distance with the doors open has a parallel to process safety. Apparently, problems were observed by the driver with the door closing system and he requested permission to override it and operate it manually. After getting the permission, he apparently did operate the doors manually in a few stations, but forgot to do so at one.
When you authorise trip or override bypasses due to a malfunction, the sense of vulnerability must increase ten fold with close supervision to prevent human error remember WHERE HUMAN, THERE ERROR!
