Customer Relationship Management (CRM) involves managing a company's interactions with current and potential customers across various channels. It encompasses sales, marketing, customer service, and other applications used to attract and retain customers. CRM has evolved from a focus on products to prioritizing customers through personalized experiences. Vendors offer various CRM systems that integrate customer data and automate processes to improve customer service and increase sales. While CRM has grown rapidly, some companies still struggle with implementation challenges and high costs. The future of CRM is focused on more individualized, real-time interactions across expanding electronic channels.
