What type of systems do many companies implement to integrate all customer-related events and transactions?

Customer Relationship Management (CRM) systems are designed specifically to manage a company's interactions with current and potential customers. These systems help businesses streamline processes, enhance customer service, and improve customer relationships by integrating all customer-related events and transactions into a unified platform.

CRM systems collect and analyze customer data from various touchpoints such as sales, marketing, customer service, and support. This comprehensive view allows businesses to track customer interactions, preferences, and behaviors, leading to improved communication and personalized marketing efforts. As a result, companies can better manage their customer relationships, respond to customer needs more effectively, and ultimately increase customer loyalty and satisfaction.

While other systems mentioned, such as ERP (Enterprise Resource Planning) or SCM (Supply Chain Management), handle different aspects of business operations, they do not focus specifically on customer interactions and relationships. BI (Business Intelligence) systems are more concerned with data analysis for decision-making rather than directly managing customer-related events. Thus, the specific focus of CRM systems on customer interactions makes it the correct choice for this question.
