A supplier's willingness to deal with rejected materials, fill surges in orders, and provide technical support is most influenced by maintaining good supplier relationships.

Creating teaming agreements with suppliers: This can formalize collaboration but does not inherently foster goodwill and responsiveness.

Negotiating inclusive terms and conditions: Important, but it sets the framework rather than influencing day-to-day willingness and responsiveness.

Maintaining good supplier relationships: This builds trust, encourages cooperation, and ensures that the supplier is willing to go beyond the contractual terms to support the buying organization.

Including such conditions in the statement of work: Ensures these terms are contractually agreed but may not impact the supplier’s willingness as much as a strong relationship would.

Therefore, maintaining good supplier relationships will most affect the supplier's willingness to address these issues.
