Which of the following is NOT commonly used as a control unit for territorial boundaries?

Territorial boundaries in sales management are typically defined by various criteria that help sales organizations organize their teams and strategies effectively. Control units are essential for measuring performance, allocating resources, and optimizing sales efforts.

Sales potential is a common factor, as it helps identify areas with the most opportunity for growth. This information plays a significant role in deciding how to structure territories based on where potential revenue can be maximized.

Metro area statistics also serve as a common control unit as they provide insights into demographic trends, market density, and consumer behavior in urban regions, facilitating informed territory planning.

States are often used as control units because they provide clear geographic boundaries that are simple to delineate and manage, aligning with the organizational structure of many businesses.

On the other hand, customer feedback is not typically used to define territorial boundaries. While it is crucial for understanding customer needs and experiences, it does not provide the geographic or demographic metrics that are necessary for setting territories. Instead, customer feedback is more often utilized to refine sales strategies and improve product offerings rather than to establish the structure of sales regions. Thus, it is the one element from the list that stands apart when discussing typical control units for defining sales territories.
