Which of the following is NOT a function of Service management?

Service management encompasses various functions aimed at ensuring that IT services meet the needs of the business and the users. Among the choices provided, the function of employee payroll management is not part of service management in the context of IT service management (ITSM).

Incident resolution is a core function of ITSM, as it involves managing and resolving incidents to restore normal service operations as quickly as possible. Service performance monitoring is also a critical function, focusing on evaluating and ensuring that services are performing as expected, ultimately supporting continuous improvement. Change management plays a vital role as well, ensuring that changes to services are made systematically and with minimal disruption to the business.

In contrast, employee payroll management pertains to human resources and financial functions, which are outside the realm of IT service management. ITSM is primarily centered around managing and delivering IT services, rather than administrative functions related to employee compensation or financial operations. Therefore, the option related to employee payroll management is not a function of service management, confirming it as the correct choice in this context.
