What is one primary factor for determining which groups of products belong together?

The primary factor for determining which groups of products belong together is that they deliver a solution to a similar consumer need. This concept is foundational in category management, which focuses on organizing products in a way that makes sense to the shopper. Grouping products that satisfy the same consumer need—such as snacks, cleaning supplies, or electronics—enhances the shopping experience by enabling customers to find related items easily, encourages additional purchases, and improves overall sales efficiency.

When products are aligned based on the solutions they provide, it becomes easier for consumers to make informed decisions, as they can compare and select products that fulfill their requirements. This approach also facilitates effective marketing strategies and promotional efforts, as it allows for targeting specific consumer segments who are looking for particular solutions.

Other factors like promotional pricing, exclusivity in bulk selling, or import status may have some relevance, but they do not fundamentally define the relationship between products in the way that shared consumer needs do.
