I’m refreshing our Q1 guard training and want to focus on skills that measurably improve theft detection and inventory control. Has anyone seen solid results from short modules like a 90-second RFID spot-audit per aisle, a simple 3-step EAS alarm decision tree, or structured self-checkout observation targeting concealment tells and barcode switching? If you’ve tracked outcomes (e.g., shrink delta over 8 weeks or exception-based reporting hits), I’d like to know what moved the numbers.
