What actually changed things wasn't a new tool or a new SOP. It was realizing IRA isn't something you report on β it's something you either protect every day or you don't. Every goods receipt, every issue, every transfer is a moment where the system and the actual shelf can quietly drift apart. Catch that drift the same day and it's a two-minute fix. Let it sit for three weeks and it turns into a full investigation, and usually nobody remembers what actually happened.
