Which is the CORRECT list of metrics to support CSI activities?

Technology, customer, and business is not the defined CSI metric framework - customer and business are outcome perspectives, not distinct metric categories in ITIL CSI guidance.

Business, service, and technology omits process metrics, which are essential for CSI to measure whether ITSM processes are operating effectively.

Customer, business, and process is not a recognized CSI metric set - customer and business perspectives are measured through service and process metrics rather than being standalone metric categories.

ITIL CSI defines three metric types: technology metrics (measuring component and application performance), process metrics (measuring the health and performance of IT service management processes via CSFs and KPIs), and service metrics (measuring end-to-end service performance from the customer perspective). Together these three give a complete picture needed to drive meaningful improvement.
