Print the report, audit each location on the report, and if anything's in that location, challenge it out. I've assigned each ETL (plus STL), TL, and Brand TMs an aisle to audit, which they submit to me each week (though when possible, try to do them daily as a follow-up), I keep a copy in my binder and leave a copy in a plastic holder attached to each aisle in the Backroom so that when we have DTL and/or other visits, they can just pick an aisle to see if it's being worked. Both the Flow TL and BR TL are overall responsible for getting these done.
