Final answer:
For successful supply chain management, adversarial relationships are not necessary. Successful management involves collaboration, information sharing, efficient logistics, and the integration of labor rights and technological advancements.
Step-by-step explanation:
The textbook indicates that for successful supply chain management, certain conditions need to be met. Adversarial relationships (A) are NOT required and are typically counterproductive to the collaborative nature of effective supply chain management.
Instead, a successful supply chain relies strongly on collaboration and cooperation (B), information sharing and transparency (C), and efficient logistics and transportation (D), which facilitate better decision-making and efficiency across the entire supply chain.
Enhanced technology and improved transportation methods, along with international and national policy support, can mitigate supply chain issues, while also promoting labor rights and development in the workforce.
