Final answer:
Customer Relationship Management (CRM) systems store and manage customer contact information to improve business relationships, focusing on customer retention and increasing sales by analyzing customer data.
Step-by-step explanation:
Systems that maintain customer contact information and identify prospective customers for future sales are often referred to as Customer Relationship Management (CRM) systems. These systems are designed to manage a company's interactions with current and potential customers by using data analysis about customers' history with a company to improve business relationships, specifically focusing on customer retention and ultimately driving sales growth. A CRM system helps in collecting information about customers, which can include age, preferences, and past purchase history, and also aids in identifying patterns that could indicate potential future sales opportunities.
For instance, in the case of the marketing manager for an electronics chain store, a CRM could analyze the ages of customers through the questionnaires filled out. Similarly, for the librarian, the CRM could track and analyze the data collected to determine the proportion of the library users that are children. For the political party, utilizing a CRM could help to analyze voter reactions and intentions after the debate, optimizing their future campaign strategies.
