Customer Relationship Management (CRM) involves developing and maintaining long-term relationships with strategically important customers by creating individualized relationships and carefully targeting customers and customer groups to maximize their lifetime value. CRM aims to enhance customer acquisition and retention by better understanding customer needs and wants, offering appropriate products and services, managing the sales cycle, and identifying cross-selling opportunities. Customer satisfaction results from customers' assessment of how a product or service compares to their prior expectations, and can be increased by exceeding expectations, helping customers, providing good customer service, and addressing recurring problems.
