Which tool allows Sort Operations managers to view real-time flow performance?

The correct choice, Mercury, is a tool specifically designed to provide Sort Operations managers with insights into real-time flow performance. It offers functionalities that are essential for monitoring the dynamics of operations, enabling managers to make informed decisions based on current data. Mercury's ability to display live flow metrics helps in identifying bottlenecks, optimizing processes, and ensuring operational efficiency. The tool's real-time capabilities are crucial for effective management in fast-paced sorting environments.

Other options, while they may serve important roles in operational management or performance analysis, do not specifically focus on providing real-time flow performance in the same direct way that Mercury does. Understanding the unique strengths and purposes of each tool is vital for selecting the right resource for managing sorting operations effectively.
