No, I think it's based.... The science bit comes in developing the plan.
I think there's a culture that exists in the interaction between companies and the CFIA. I've noticed this first hand. I think that some inspectors, as I was mentioning in answer to the previous question, don't really know what role they're playing. That's the only way you could explain the fact that there were such deficiencies in XL and that the inspectors didn't seem to even notice it.
I think the questioner is saying that this is what they've developed and this is how they do their job effectively. But it's clear that they don't do the job effectively, and I believe this is because their duties are ill-defined, personally speaking.
