Physical networks accumulate countless small changes in missions, preferences, and operational practice that rarely show up clearly in conventional reporting. BIEM turns spatiotemporal patterns in flow, dwell, service, and availability into a structured landscape of trends that unfold over weeks, months, and seasons. By comparing these trajectories across regions, formats, and cohorts, BIEM distinguishes noise from meaningful shifts in demand and behavior. Retailers gain a defensible basis for adjusting concepts, refining propositions, and reallocating resources in line with how their system is actually evolving.
