Standard operating procedures (SOPs) I'm just wondering why someone is "down the road" for making the same mistake continuously? Have you stopped to ask "why is this mistake happening repeatedly?". What insights to the tasks can the people who do the work offer? How do you accommodate deviation from the task procedure, which may well occur? The task hazards are always present, you need to build in capacity to allow this. There's some great advice & presentations online by Todd Conklin on this topic.
