Leaky bucket diagram

"The leaky bucket theory The leaky bucket theory is the model that seeks to describe the process of customer gain and loss, otherwise known as customer churn . Customer retention is one of the key concepts in relationship marketing. Most companies concentrate on recruiting new customers to replace customers who move on, rather than seeking to retain customers." [Blythe J. Key Concepts in Marketing. 2009. knowledge.sagepub.com/ view/ key-concepts-in-marketing/ n5.xml]
"Customer attrition, also known as customer churn, customer turnover, or customer defection, is the loss of clients or customers.
Banks, telephone service companies, Internet service providers, pay TV companies, insurance firms, and alarm monitoring services, often use customer attrition analysis and customer attrition rates as one of their key business metrics (along with cash flow, EBITDA, etc.) because the "...cost of retaining an existing customer is far less than acquiring a new one." Companies from these sectors often have customer service branches which attempt to win back defecting clients, because recovered long-term customers can be worth much more to a company than newly recruited clients."

This Venn diagram sample depicts the relationship marketing.
"Relationship marketing was first defined as a form of marketing developed from direct response marketing campaigns which emphasizes customer retention and satisfaction, rather than a dominant focus on sales transactions. As a practice, relationship marketing differs from other forms of marketing in that it recognizes the long term value of customer relationships and extends communication beyond intrusive advertising and sales promotional messages. With the growth of the internet and mobile platforms, relationship marketing has continued to evolve and move forward as technology opens more collaborative and social communication channels. This includes tools for managing relationships with customers that goes beyond simple demographic and customer service data. Relationship marketing extends to include inbound marketing efforts, (a combination of search optimization and strategic content), PR, social media and application development."
