"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."

"The classical breakdown of all economic sectors follows:
Primary: Involves the retrieval and production of raw materials, such as corn, coal, wood and iron. (A coal miner and a fisherman would be workers in the primary sector.)
Secondary: Involves the transformation of raw or intermediate materials into goods e.g. manufacturing steel into cars, or textiles into clothing. (A builder and a dressmaker would be workers in the secondary sector.)
Tertiary: Involves the supplying of services to consumers and businesses, such as baby-sitting, cinema and banking. (A shopkeeper and an accountant would be workers in the tertiary sector.)
In the 20th century, it began to be argued that traditional tertiary services could be further distinguished from "quaternary" and quinary service sectors." [Economic sector. Wikipedia]
