Thanks for your replies. I guess discipline can show the sense of importance of SOP steps, following processes, etc. but can it also lead to tunnel vision when it comes to root cause analysis? For example, it seems convenient that corrective actions become blame oriented. Things like "retrain operators", "discipline operators", "revise SOP" and the like may prevent digging deeper. Also, is it possible that this could hurt morale and lead operators to not be as forthcoming with information or "near hits"? Do regulatory agencies view "counsel operators", retrain operators, etc. as viable corrective actions?
