The number of business processing hours lost due to unplanned service interruptions would be an appropriate metric associated with an enterprise goal of business service continuity and availability. A metric is a quantifiable measure that is used to track and assess the status of a specific process or activity. Business service continuity and availability is one of the 17 generic enterprise goals defined by COBIT that describes the desired outcome of ensuring that critical business services are delivered at agreed levels and are resilient to disruptions. The number of business processing hours lost due to unplanned service interruptions is a metric that reflects how well this outcome is achieved.13 References: COBIT 2019 Framework: Introduction and Methodology, COBIT 2019 Framework: Governance and Management Objectives
