Yes. I wasn't there when the process was implemented, but I am familiar with it. It was implemented as an early response to what we saw as forthcoming legislation or regulation, and we explained that to our contractors. We explained our values, of which safety is paramount. They were able to buy into that. We were able to explain the process to their managers and then later to their employees.
We used, as we always try to do, some sound change management principles to make sure that we had buy-in to the extent we could get it from the front lines and all the way through the system.
