Which one of the following is it the responsibility of supplier management to negotiate and agree?

Service Level Agreements (SLAs) are negotiated and agreed by the Service Level Management process, which manages agreements with customers, not external suppliers.

Third-party contracts are the primary output of Supplier Management - this process identifies, evaluates, and manages external suppliers, and is specifically accountable for negotiating contractual terms, performance targets, and obligations with those suppliers to protect the organization's interests and service continuity.

The service portfolio is governed by Service Portfolio Management as part of the Service Strategy stage, which is outside the scope of Supplier Management.

Operational Level Agreements (OLAs) are internal agreements between IT departments and are the responsibility of Service Level Management, not Supplier Management.
