Final answer:
The correct order along the value chain for the four business functions is Design, Production, Marketing, and Customer Service. This process takes a concept through various stages of development, production, and after-purchase support.
Step-by-step explanation:
In the context of the value chain in business, the correct order of the functions as they appear along the value chain is Design, Production, Marketing, and Customer Service. The sequence starts with Design, where a product is conceptualized and engineered.
Next is Production, where the product is actually created and assembled. Following Production is Marketing, which involves promoting and selling the product to the target market. The last step is Customer Service, which involves supporting and addressing the needs of the customers who have purchased the product.
To illustrate this with an example such as the production of an iPhone, the process would involve designing and engineering in the United States, component supply from various countries like Korea, assembling in China, marketing and advertising in the United States, and providing customer support globally.
