Description: Availability metric is a critical measure in the realm of service quality that evaluates the time during which a service or system is operational and accessible to users. It is commonly expressed as a percentage, where 100% indicates that the service is available at all times, while 99% suggests that there has been some downtime. This metric considers not only uptime but also planned and unplanned downtime, making it a comprehensive indicator of service reliability. Availability is essential in environments where service continuity is crucial, such as telecommunications, cloud services, and critical information systems. The availability metric is used to assess the performance of technological infrastructures and to establish service level agreements (SLAs) between providers and clients. High availability is a desired goal, as it directly impacts customer satisfaction and operational efficiency within organizations. In summary, the availability metric is a fundamental component in service quality management, providing a clear view of a system’s ability to meet user expectations in terms of accessibility and reliability.
