Identify a tool commonly used for monitoring system reliability.

The Supervisory Control and Data Acquisition (SCADA) systems are a vital tool for monitoring system reliability. SCADA is primarily used in industrial environments, particularly within energy and utility sectors, to collect real-time data from various sensors and control devices. These systems enable operators to monitor the performance and health of equipment, providing crucial insights into the operational state of the power grid or any other monitoring environment.

Through SCADA, operators can observe parameters such as voltage, current, frequency, and system alerts, allowing for immediate response to potential issues. This real-time monitoring enhances overall reliability since operators can identify and address problems before they escalate into serious failures. Moreover, SCADA systems support decision-making processes by providing historical data and analytics, contributing further to system reliability improvements.

In contrast, other tools such as Human Resource Management Systems, Geographic Information Systems, and Customer Relationship Management tools serve different functions that are not directly aligned with the continuous monitoring and operational reliability of systems like SCADA does.
