Step-by-step explanation:
The area in a business responsible for analyzing consumer trends and ensuring that product assortments reflect these trends accordingly is typically found within the marketing department or a specialized retail analytics team. These professionals leverage a mixture of market research, consumer behavior analysis, and geographic information systems (GIS) to monitor shifts in consumerism and adjust product offerings to meet the evolved demand.
For example, with the advent of department stores, there was a recognizable shift towards modern buying patterns, emphasizing the importance of tracking consumer trends for effective product assortment. Similarly, geographers use GIS tools to quickly identify where trends align or diverge from predictions, allowing businesses to tailor their strategies regionally.
