Final answer:
The correct answer is A) Supply Chain.
Step-by-step explanation:
The system of companies and activities that takes a product from an idea to final delivery to a Mary Kay customer describes the various stages through which a product must pass before reaching the end user. This system encompasses the identification and procurement of raw materials, product design and development, manufacturing, transportation, and distribution to finally reach the end user. The concept that best illustrates this entire process is Supply Chain.
The supply chain represents the interconnected network of businesses involved in delivering a product from the supplier of raw materials through to the manufacturing processes and, finally, into the hands of the customer. It includes design, production, shipment, and marketing. In this context, the Mary Kay company would have to develop a manufacturing system, locate suppliers, establish facilities, and hire a sales and marketing team, reflecting the interconnected businesses in the Circular Flow Model which produces goods and services in the economy.
Moreover, the concept of the value chain explained in international trade, where different stages of production are split into highly specialized tasks, aligns with the idea behind a supply chain.
It is important to note that the value chain and the supply chain are often closely related, as the value chain describes the internal activities a firm engages in when transforming inputs into outputs, which is a subset of the overall supply chain management. Specialization and splitting up of the value chain across different countries illustrate the complexity and global nature of supply chains today.
