Availability Management is responsible for availability of the:

ITIL defines Availability Management as responsible for ensuring that all IT services meet their agreed availability targets by monitoring and managing both the services themselves and the infrastructure components that support them. Business processes are not within its direct scope - they are owned by the business and fall under separate disciplines such as Business Continuity Management. This distinction keeps Availability Management focused on measurable IT metrics like MTRS, MTBF, and MTBSI.

Business Processes are outside the defined scope of Availability Management in ITIL; business process continuity is the responsibility of the business or Business Continuity Management.

Components alone paired with Business Processes misrepresents the ITIL scope by omitting Services and incorrectly including Business Processes.

Although Services and Components are correctly included, adding Business Processes extends the scope beyond what ITIL formally assigns to Availability Management.
