Mr. Robert Watt:

We all make mistakes. I know the Deputy wants a short answer. It is important to have an environment where it is made clear to people that repeated mistakes will be dealt with. Equally important, and probably more important, is that when people try something and make a mistake that they now learn from why they made that mistake. It is much more important to have a learning culture and a supporting learning culture as opposed to the "gotcha" culture. In my experience as a public servant the vast majority of people do their best, work hard and try. They do not go out to make mistakes.
