Which one of the following generates demand for services?

Infrastructure trends describe technological evolution and capability changes, not the business activities that drive demand for services.

In ITIL Service Strategy, Demand Management uses Patterns of Business Activity to understand how and when the business consumes IT services, including daily, weekly, or seasonal fluctuations. These patterns translate business activity directly into demand signals, enabling the service provider to align capacity and resources with actual business needs.

The cost of providing support is a financial input to service management decisions and does not generate demand for services.

Service level agreements define agreed service targets and scope but do not themselves generate demand - they govern services that are already in demand.
