A manufacturer compares suppliers that can quickly change order quantities. Which strategy is being pursued?

Backward vertical integration involves a company acquiring or merging with suppliers to gain control over its supply chain. While this can improve efficiency and reduce costs, it does not inherently provide the flexibility to change order quantities quickly, as it focuses on control rather than responsiveness to demand fluctuations.

Forward vertical integration refers to a company's extension of its operations into the distribution or retailing of its products. This strategy aims to increase market control and customer access but does not directly address the need for quick adjustments in order quantities, which is the focus of an agile supply chain.

A lean supply chain focuses on minimizing waste and improving efficiency by optimizing processes and reducing inventory levels. While it can lead to cost savings and streamlined operations, it may lack the flexibility required for rapid changes in order quantities, as the emphasis is on efficiency rather than agility.
