How can partners and suppliers support the 'service desk' practice?

Partners and suppliers in ITIL 4 play a significant role in supporting service management practices, including the service desk. The key is understanding how they can complement and enhance service operations through their expertise and resources.

A. By reducing the need to customize the IT services: This option relates more to service design or service development. It doesn’t specifically align with how partners and suppliers would support the operational and communication-focused aspects of the service desk​.

B. By advising on how to build the team and implement an information system(Correct Answer): Partners and suppliers often provide expertise in areas such as team structuring, system implementation, and best practices. In the context of the service desk, external expertise can be invaluable in setting up effective service desk operations, selecting and implementing tools for managing communication, and ensuring smooth integration with other IT operations​​.

C. By providing problem management tools: While problem management tools are valuable, they are more directly aligned with theproblem managementpractice rather than supporting the service desk. The service desk focuses on communication, incident capture, and request management​.

D. By outsourcing the development of IT services: Outsourcing the development of IT services is more aligned with service delivery and design. While external service providers may offer support for technical services, this does not directly support the service desk’s operational focus​​.

Therefore,Bis the correct answer as it clearly reflects how partners and suppliers can support the service desk practice through advice on team building and systems implementation​​.
