Thank you very much.
It's a very good question and I totally agree with you. That's why we can't rely completely on artificial intelligence to draw conclusions. We have to have people who are going to review the data and be able to interpret it, people who know the industry. The people with whom I staff our procurement team, I select primarily from the construction industry. They are engineers, architects, or technologists who have worked in construction, because we need that knowledge to be able to interpret the data.
That's why we can't rely on just one statistical analysis. We have to do several of them so we can establish a trend. We cannot draw a conclusion from the coefficient of variance on its own. We have to do another one, and then another one, and another one, and we need to do further research into the file. It takes a lot of effort really to get down to being able to draw from it that, yes, there's more likely to be collusion than not.
