In answer to a question of how to avoid the pitfalls of diving beyond training / experience, I was referred to this Four Part series on "Normalization of Deviance". If you work or play in a team, this is a premiere seminar on how standards slide, and how to recognize that and stop it.
Below is part 1. YouTube will display the others on the same page. I hope you enjoy this energetic and enlightening speaker as much as I.
