Which of the following should a CIO review to obtain a holistic view of IT performance when identifying potential gaps in service delivery?

Key Performance Indicators (KPIs) provide a holistic view of IT performance because they are strategic metrics designed to measure the success of an organization or a particular activity against its objectives. A CIO can track various KPIs related to availability, reliability, security, cost-efficiency, and project delivery to identify potential gaps across all aspects of service delivery and IT operations, offering a comprehensive overview.

Return on investment (ROI) analysis focuses specifically on financial gains relative to costs, not a broad measure of operational service delivery performance.

Service Level Agreement (SLA) reporting specifically measures adherence to agreed-upon service levels but does not offer a holistic view of *all* IT performance aspects beyond those defined in the SLAs.

Staff performance evaluations focus on individual employee performance, not the overall performance or service delivery of the IT department as a whole.
