Developing relationships with a small number of suppliers can provide several advantages, but the best reason in a supply management context is:

To identify innovation opportunities: While important, this can be achieved with both few and many suppliers.

To obtain pricing improvements: Focusing on fewer suppliers often results in better negotiation leverage and volume discounts, leading to pricing improvements.

To decrease internal cultural barriers: This is less directly related to supplier relationship management.

To improve sourcing opportunities: This can be done with multiple suppliers as well.

Thus, the best reason to develop relationships with a small number of suppliers is to obtain pricing improvements.
