Step-by-step explanation:
The tool that allows companies to determine which customers are most valuable so they can react in a timely manner with products that closely match customer needs is Customer Segmentation. Customer segmentation is the process of dividing customers into groups based on similar characteristics such as demographics, behavior, or purchasing patterns. By analyzing these segments, companies can gain insights into their customers' preferences and tailor their products or marketing strategies to meet their specific needs.
For example, a clothing retailer may use customer segmentation to identify groups of customers who are most likely to purchase certain types of clothing, such as athletic wear or formal attire. They can then target these segments with customized promotions or product recommendations.
Other tools that can help companies determine customer value include customer lifetime value (CLV) analysis, which calculates the projected revenue a customer will generate over their entire relationship with the company, and customer satisfaction surveys, which measure customer satisfaction and loyalty.
