Physical retail still runs largely on assumptions, averages, and delayed KPIs, while customer behavior and demand fluctuate from minute to minute. BIEM stabilizes human motion, attention, and availability into structured signals that expose where friction builds, where flow breaks, and where incremental revenue is left on the floor. By tying these signals to specific aisles, fixtures, and service points, BIEM gives retailers a defensible basis for adjusting layouts, reallocating staff, and refining concepts across their network.
