ITIL 4 Specialist Collaborate, Assure and ImproveDemo

ITIL 4 supplier management practice treats operational tasks such as scanning the market for candidate suppliers, onboarding a chosen supplier, and monitoring ongoing supplier performance as activities that can reasonably be delegated to a service integrator or specialist third party acting on the organization's behalf. Documenting how supplier management activities will be performed, however, defines the organization's own policy, controls, and accountability framework for governing supplier relationships. Delegating that documentation effectively hands over ownership of the organization's governance model to an external party, which undermines the oversight supplier management exists to provide, so it is the activity organizations retain internally rather than delegate.
