Customer relationship management (CRM) involves using technology to manage a company's interactions with current and future customers. The goal of CRM is to create value for both customers and the company over the long term by gaining competitive advantage through sales strategies, promotions, improved customer service, and building long-term relationships. CRM uses technology to store customer data, track purchase histories, and target customers with personalized services to meet their needs. Key challenges for CRM include ensuring rich customer data, an integrated view of information, effective feedback mechanisms, intelligence at customer touchpoints, and consistent communication.
