What is meant by the value chain in industry?

• A. A ledger of raw materials inventory.
• B. A production line with maximum speed.
• C. The value chain is the sequence of activities that add value to a product from input to final consumer, including design, production, marketing, distribution, and after-sales service.
• D. The accounting method for depreciation.

Answer: (C)

Value chain denotes the sequence of activities that add value to a product as it moves from inputs to the final consumer, including design, production, marketing, distribution, and after-sales service. This framework helps a company see how each step contributes to the product’s worth and where value is created or costs arise, guiding improvements to boost overall competitiveness and customer value. The other descriptions focus on isolated aspects—inventory management, throughput of a production line, or financial accounting for asset depreciation—none of which capture the full series of value-adding activities from idea to customer.
