The primary function of a reliability metric is to indicate the system's reliability and availability. Reliability metrics are essential tools in the field of reliability engineering as they provide quantifiable measures of how well a system performs over time without failure. These metrics help organizations gauge the performance of their products, allowing them to understand the likelihood of failure and the expected uptime of the system. By focusing on reliability and availability, these metrics enable engineers and managers to identify weaknesses in designs, improve maintenance schedules, and reduce downtime, ultimately enhancing customer satisfaction and product performance.

While factors like aesthetics, user accessibility, and development costs are important in the broader context of product development and user experience, they do not directly reflect the reliability and operational performance of a system.
