Which of the following is an example of a Key Performance Indicator (KPI)?

Mean Time Between Failures (MTBF) is a crucial Key Performance Indicator in a network context because it provides valuable insights into the reliability and availability of network components. MTBF measures the average time between failures of a system, allowing network administrators and stakeholders to gauge performance, plan maintenance schedules, and assess the efficiency of service delivery.

KPIs are quantifiable metrics that help in evaluating the success of an organization or a particular activity in which it engages. MTBF serves this purpose effectively, as it directly correlates to operational performance, indicating how often equipment is expected to fail over a given time frame. This information is vital for improving system reliability, optimizing maintenance processes, and ensuring that service levels meet organizational standards and customer expectations.

While bandwidth usage, network latency, and device temperature are important metrics for analyzing network performance or health, they do not encompass the broader strategic implications and predictive capacity that MTBF offers in terms of performance measurement and operational efficiency.
