BIG designs tiered hybrid field models: dedicated Territory Managers own priority stores, a wider CSR network protects availability, compliance and POS execution across the rest, and a National Field Sales Manager provides oversight and KPI governance across both layers. Call frequency is tiered by store size, performance and opportunity — weekly for priority and large-format stores, fortnightly for mid-tier, monthly for lower-volume — delivering dedicated commercial ownership exactly where it matters, with scalable, disciplined execution across the whole network.
