All stages of an enterprise are involved, either directly or indirectly, in fulfilling a customer request

The above statement is true.

Customer request refers to the needs of a consumer of a particular good or service. Customer relates to an individual or firm that purchases a good or service from a supplier, intending to use the goods. Any enterprise aims to fulfill the customer needs because without fulfilling their needs, no consumer will consume the firm's products; thus, the firm will not make a profit. Since any enterprise aims to make a profit, all its operations should directly or indirectly contribute to consumers' fulfillment. Consumers will not purchase goods that do not fulfill their needs since they will be non-useful to them. Hence, the above statement is true when it argues that an enterprise involves the consumer needs in all of its stages.
