What concept describes the comprehensive approach to customer interactions over time?

The concept that best describes the comprehensive approach to customer interactions over time is Customer Relationship Management (CRM). CRM encompasses the strategies, practices, and technologies that organizations use to analyze customer interactions and data throughout the customer lifecycle. The main goal is to improve customer service relationships and assist in customer retention and satisfaction. By effectively managing these interactions, businesses can foster loyalty, drive sales growth, and enhance overall customer experiences.

This system not only involves maintaining detailed information about customers but also includes communication strategies and marketing techniques tailored to different stages of the customer journey, ensuring that the business can interact consistently and beneficially over time. Through CRM, companies can better understand customer needs, preferences, and behaviors, enabling them to create personalized experiences that resonate with their audience.
