Have you ever wondered or do you even care that after much repeated training over a long period of time, people still forget or even deliberately neglect to do the right things?
Yes I care and have wondered (often). If you have a poor culture then training is a waste of time. I think what you mention is more about good leadership and management that develops a positive culture rather than training. This doesn’t mean “soft” it means performance is measured, checked, audited, discussed, reviewed and if things continue to fail even after training then we ask why and put it right. It may not necessarily be the operators fault they may have poor leadership, information, equipment etc. We have to look at any problem or business need from all angles and set about it in a rounded way and training is just one (important) part of the solution.
Personally I look at every problem with a fishbone or cause and effect diagram in my mind and ask what are the causes related to Man, Method, Machine, or Material. There are usually multiple causes.
By the way I’m not calling you a lunatic – as I said using those words in a manufacturing environment would be scorned upon and are not very meaningful or practical to most people.
