The correct answer to this question is A. Technology metrics measure components, but they do not measure processes, the end to end service, or customer satisfaction. In addition to technology metrics, the other two primary categories of measurement include process and service. Technology metrics measure specific aspects of the IT infrastructure and equipment, and include component and application measurements like performance and availability. Process metrics are defined and measured using guidelines like critical success factors (CSFs) and key performance indicators (KPIs). Service metrics are a measure of end-to-end service performance. A metric is a scale of measurement defined in terms of a standard.
