Final answer:
Value stream costs typically include raw materials, labor costs, and overhead expenses, but not sales revenue.
Step-by-step explanation:
The value stream cost is the cost associated with producing and delivering a product or service to a customer. It includes costs such as raw materials, labor costs, and overhead expenses, as these are all directly related to the production process. Sales revenue, on the other hand, is not considered a value stream cost because it represents the income generated from selling products or services, rather than the cost of producing them.
