That's only the first part of the process though, to identify a skillset. Then you scout them. I fully expect that "scouting" is more than just sitting in the stands and watching them play. They'll also look into his character etc.
The stupid process was going out and buying players without doing that due diligence. The first player than springs to mind there is NDombele.
I don't know how the full process works, but that's my limited understanding of it. The key here is data "led." It's not the sum total of the process.
