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

Technology, customer, and business is incorrect because 'customer' is not one of the three defined CSI metric categories; process metrics replace it in the correct grouping.

Business, service, and technology omits process metrics entirely and substitutes 'business' which is not a defined metric category within the ITIL CSI measurement framework.

Customer, business, and process does not match the ITIL CSI metric categories; neither 'customer' nor 'business' are the defined metric types - technology and service metrics are missing.

ITIL continual service improvement defines three metric types: technology metrics (component and application performance), service metrics (end-to-end service performance), and process metrics (effectiveness and efficiency of service management processes measured via CSFs and KPIs). All three together provide the complete measurement picture required to identify gaps and prioritize improvements.
