How Walmart Is Using Big Data & IoT

at the center of (something): ~의 중심에
That gives us a great opportunity to put the customer right at the center of what we do.

competitive marketplace: 경쟁적인 시장
seamless shopping experience: 원활한 쇼핑 경험
In today’s highly competitive marketplace, grocery retailers strive to create a seamless shopping experience that drives sales and builds loyalty with their customers.

exposure to promotions: 광고 노출
product interaction: 제품 상호 작용
IoT data is used to track the effectiveness of store layouts, exposure to promotions, product interactions, and use of digital kiosks and mobile apps.

upsell: 상향 판매하다 (기존 고객이 사용하는 제품의 상위 버전을 구매하도록 유도하는 마케팅)
cross-sell: 교차 판매하다 (아직 사용하고 있지 않은 제품을 소개하고 추가구매를 유도하는 마케팅)
For marketers, identifying customer desire, delivering curated content to upsell and cross-sell and measuring the success of promotions has never been simpler and more accurate.

eliminate long queues: 긴 줄을 없애다
cognitive intelligence: 인지 지능
IoT provides service level metrics and enables store managers to eliminate long queues, schedule staff efficiently through cognitive intelligence, and make sure customer expectations are being met at every service point in the store.
