My understanding is that they were tracking significantly fewer parts in Excel as many of what they are now tracking as separate parts were previously tracked as a single part (kind of an assembly). I think they were previously tracking somewhere in the 100-200 parts in Excel.

My understanding for why this is coming out now is that there was a talk Vowles has done recently where he mentioned the massive hit getting ready for this season because they changed both Excel into the new ERP systems AND started tracking each individual part, which complicated the transition and why it was such a rush for Williams to be ready for this year.
