Too often "retraining" or "discipline" is selected impulsively to correct a discrepancy between what people do and what we want them to do. As I mentioned last month, workers will take risks for a variety of reasons. Perhaps they don't know what's expected, or they don't have the right tools or enough time. Sometimes people are rewarded for the wrong behavior, or ignored or punished for performing the safe way. Useful feedback may be missing.
In these cases, people know what to do, but they just aren't doing it. They are "consciously incompetent." The problem is not lack of knowledge or skill. Training is not the answer. You need to analyze and change organizational systems, workplace conditions, and interpersonal relations.
