THE FAMILY TREE MODEL

THE CONTACTS YOU SHOULD MAINTAIN
This model is based on the premise that humans are fundamentally social, interactive beings. Brand Loyalty can be understood as a persons's attachment to a brand or product and that persons desire to tell others about it. Conventional models for determining brand loyalty often serve as a justification of often imprudent expenditure of decision that have already been made rather than as an objective evaluation of strategies.
A simpler and more constructive starting point for determining brand loyalty is to find out what your customers think about your product instead of a complex questionnaire, in this model the customer is asked a single question: 'Who recommended this product to you, and who would you recommend it to? Three groups of respondents can be defined based on the answers: promoters, passive satisfied customers and critics. The ratio of promoters to critics in the barometer of success.
Draw a client or portfolio structure in the shape of a family tree. Now you will see how or whom a client became a client.
HELP INTERPRETATION
The more family trees you have to draw, the more diverse your customer  structure or portfolio. Boughs with more branches require more maintenance. They represent a risk over- concentration and can easily break.

You don't have customers? Then think about your circle of friends and acquaintances is structured. through whom did you meet most of your friends? Are you still friends with this person.
