How to Create a Concept Map

This concept map example shows concepts and relationship in the geopolitical ontology.
"A geopolitical ontology is a mechanism to describe, manage and exchange data related to geopolitical entities such as countries, territories, regions and other similar areas. ...
An Ontology is a kind of dictionary that describes information in a certain domain using concepts and relationships. It is often implemented using OWL (Web Ontology Language), an XML-based standard language that can be interpreted by computers." [Geopolitical ontology. Wikipedia]

This marketing diagram sample illustrates leaky bucket model.
"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."
