Final answer:
The correct statement regarding a supply chain is that it encompasses all participating organizations from raw material sourcing to delivery to consumers, including handling returns and maintaining ethical labor practices.
Step-by-step explanation:
The true statement about a supply chain is number 2, which states that a supply chain includes all organizations that contribute to the development, manufacture, and shipping of products to a consumer.
A supply chain is a network of entities involved in producing and delivering a product or service to consumers. It encompasses a sequence of activities that include sourcing raw materials, production, and distribution of finished products. This process often spans multiple companies and can cross international borders, leading to specialization and a division of labor. For instance, a product like an iPhone is designed in one country, parts are supplied from another, and assembly occurs in a third. Improvements in communication and transportation have facilitated this specialisation, enabling firms to split up the value chain, optimize costs, and expedite delivery.
The concept of a supply chain also extends to labor policies and the handling of returns. To achieve a more efficient and ethical supply chain, companies are encouraged to invest in their labor force and protect labor rights. Advanced technologies and international collaboration help in maintaining supply chains, especially during crises such as national emergencies, thus demonstrating the comprehensive nature of modern supply chains.
