I think for all of the carriers here, our SMS programs have gone through numerous iterations through time—because we have some time under our belts here—and there definitely has been a maturing of the programs. In fact, we can much more often now see a direct link between outcomes—somebody mentioned injury rates, for example—and working back and being able to demonstrate that those happened because of the SMS itself.
That's a key point here, because this is what Transport Canada does in their oversight role. They want to see the link. They want to see how the processes you have in place have actually had a causal effect on some sort of worthwhile outcome.
With Jazz, we have been able to demonstrate that perhaps it was a result of a risk assessment and something we did there, or the result of a communication campaign.
That's a sign of the maturity: when you can start to show that the system is what made the change.
