What aspect does the tab-based capacity model measure?

The tab-based capacity model specifically measures the number of open console tabs in the service console. This model is designed to help organizations understand how many concurrent tabs can be handled within the service environment without degrading performance or user experience. By monitoring this metric, organizations can ensure that their service agents are working efficiently and have the necessary tools readily available while maintaining system stability.

Measuring the number of open console tabs is crucial for optimizing agent productivity and can help in troubleshooting performance issues that arise when too many tabs are open. It aids in capacity planning to ensure that agents have an optimal working environment, ultimately contributing to higher efficiency in handling customer requests.

This focus on the service console tabs distinguishes the correct answer from other choices, which pertain to different aspects of service performance or agent management that are not directly about tab management.
