Which system would an engineer implement to manage and automate workflows across multiple sites?

The choice of SCADA (Supervisory Control and Data Acquisition) is correct because SCADA systems are specifically designed to manage and automate workflows across multiple sites in various industrial and infrastructural environments. These systems allow for the control and monitoring of processes remotely, which is crucial for operations that span large distances or involve multiple facilities.

SCADA systems collect real-time data from sensors and devices located at various sites and present it in a centralized interface, enabling operators to analyze information, monitor system performance, and make informed decisions to optimize workflows. This capability fosters efficient management of resources, quick response to alarms or system failures, and better overall coordination across different locations.

The functionalities of SCADA are particularly important in industries such as utilities, manufacturing, and transportation, where centralized control over distributed assets is essential for operational efficiency and effectiveness.
