I think the example is a very good one.
The emphasis is on being proactive. In the past the systems were reactive: operators would react to a problem, and we would also react to that. When it came to our level, our expectation is they're proactive in managing safety along the lines of what Mr. McDonald just explained by way of example, to look for problems and to identify solutions so that, generally speaking, they're generally ahead of the problems.
The research basically shows that by doing that, you deal with all the little things. Hopefully, they'll never build up to the point where you get a critical situation. In the past, that level of attention was not being paid to details on a regular basis. The industry people who get it really make a huge difference to us in terms of their performance.
