Which of the following systems is responsible for managing relationships between a company and its suppliers?

The answer is correct because Supply Chain Management Systems are specifically designed to manage and optimize the flow of goods, information, and finances related to supplier relationships within the supply chain. These systems ensure that a company can effectively interact with suppliers, manage inventory levels, track orders, and optimize logistics, all of which are critical components in maintaining strong supplier relationships and ensuring efficient operations.

In contrast, Customer Relationship Management systems focus on managing interactions and relationships with customers rather than suppliers. Knowledge Management Systems are designed to capture, distribute, and effectively use knowledge within an organization, which doesn't directly address supplier management. Decision Support Systems assist in making informed business decisions based on data analysis but do not focus specifically on managing supplier relationships. Thus, the role of Supply Chain Management Systems in overseeing supplier interactions makes them the most appropriate choice for this question.
