Customer Chain

The Customer Service ChainEach one of these groups is part of the broader customer chain, some as internal customers, others as external customers. An external customer is someone who directly purchases the products or services of a business enterprise. An internal customer is a group in the distribution channel that receives processes, products and services from others in the organization. For example, your teachers are customers of one another. If you fail to become a proficient reader or writer after taking English classes, you will not be an effective student in a history class. In this case, the history teacher is an internal customer of the English teacher.
