Thank you for the question.
I think, as it relates to our external contracts, it's similar with almost any contracting vehicle. We have a quality assurance process, and we do take a look at the different providers, especially if there's one where we're seeing a consistency and there's a concern with the level of quality we're getting out of them. You would usually start out with a conversation and work your way down to see if this is something that's a bit more permanent, in which case we do have the ability to knock off suppliers if they're not responding to our needs.
Internally it becomes a human resource issue. Is the person not well trained or simply performing poorly? You investigate and then you respond accordingly.
