Purpose
Intelligence studies that involve integrated consumer and shopper ethnography work which measures and understands shopper behaviour as different from consumer behaviour.

Process
Consumer purchase hierarchy, attitudes and consumption of a product or category
. to understand the consideration set and how brand decisions are made
. to diagnose with the shopper component, if these consumer attitudes and disposition are    leading to purchases and identify triggers for purchase/non purchase

. Store layouts need to reflect whether customers shop by brand, size, color, price point.Customer willingness to substitute one brand for another, for example, is valuable information for assortment planning

. People will bend to pick up regular purchases but may not make the effort for new/unknown products

. People find it easier to read/notice at eye level and instinctively reach out to the right side to pick up

. Placing newer products at end of aisles may be better than the middle as middle is a more focused shopping area

. Recent work in India shows that there is on an average a 50% propensity to switch brands inside a store
