Final answer:
The number of sellers is not a basic area of consideration in supplier management. The costs of production, prices of related goods, and sellers' expectations are important factors.
Step-by-step explanation:
In supplier management, the basic areas of consideration include the costs of production, the prices of related goods in production, sellers' expectations, and the number of sellers. These factors are important in determining the overall efficiency and effectiveness of the supplier management process.
However, the number of sellers is NOT a basic area of consideration in supplier management. This is because the number of sellers does not directly impact the costs of production, the prices of related goods, or the expectations of sellers.
It's crucial for businesses to focus on the relevant factors that influence supplier management in order to maintain strong relationships with suppliers and maximize operational efficiency.
